Audi cars are equipped with an engine coolant system that helps to keep the engine at a consistent temperature. Your Audi’s coolant circulates through the engine block and radiator, absorbing heat from the engine. The coolant then flows back to the radiator, where it is cooled before being circulated back through the engine block.
Audi designed its engine coolant system to keep the engine coolant at a consistent temperature, even in extreme conditions. Audi recommends that you check the level of your coolant at least once a month. If the level is low, add more to the reservoir so your engine doesn’t overheat and cause major, expensive problems. It is also recommended that you have your engine coolant system flushed and filled every two years. Let’s take a closer look.
Watch for Signs of Trouble with Leaks
Audi is committed to engine safety and performance, and that’s why they recommend that you keep your engine running with coolant. Audi coolant has been specifically designed to protect your engine from overheating and corrosion. Audi coolant contains an antifreeze agent that prevents the coolant from freezing in cold weather, and a rust inhibitor that helps to protect your engine from corrosion.
This coolant also contains a built-in dye that makes it easy to check for leaks. The most common Audi leak is the coolant expansion tank. The Audi coolant expansion tank is located on the passenger side of the engine, near the front of the vehicle. The tank is made of plastic, and over time, it can crack and leak coolant.
Audi has actually issued a service bulletin to replace the coolant expansion tanks on affected vehicles. It’s important to check the coolant level regularly and look for signs of leaking and if you suspect your Audi model has a leak, bring your car to our qualified mechanics to have it checked out.
Coolant leaks can be hard to detect, so it’s important to know what to look for. One telltale sign of a coolant leak is a sweet, syrupy smell coming from under the hood. Another sign is low coolant levels in the radiator or expansion tank. If you see either of these signs, it’s important to have it repaired as soon as possible. Coolant leaks can cause serious damage to your engine if they’re not fixed, so don’t ignore them!
Wrong Coolant, Radiator Damage, and Cracked Hoses
There are several reasons why your coolant may leak or cause problems as it circulates throughout the engine. Audi has a complex cooling system with multiple hoses and connectors. Over time, these components can wear out or become loose, causing coolant to leak.
Your Audi’s radiator is located at the front of the car, making it vulnerable to damage from road debris. If a rock or piece of debris hits the radiator, it can cause a coolant leak.
Finally, Audi’s use a type of coolant that is not compatible with all types of antifreeze. If the wrong type of antifreeze is used, it can eat away at seals and gaskets, causing leaks.
If you notice your Audi is leaking coolant, it’s important to take it to a trained mechanic right away so the problem can be fixed before it causes serious damage.
Turning Wrenches
There are several coolant leak remedies that 
our mechanics can choose to fix your car. The Audi coolant system is designed to keep the engine at a consistent temperature, and when it leaks, the engine can overheat. That said, the solution will depend on where the Audi coolant leak is coming from.
If the coolant level is low, our mechanics will simply need to top it off. However, if there is a hole in your Audi’s coolant system, our mechanics will need to locate the source of the leak and patch it up. In either case, our mechanics have the experience and expertise to quickly and efficiently fix your Audi’s coolant leak.
No matter what kind of Audi you drive, you want the best from your car each time you get behind the wheel. At Turning Wrenches, we offer complete Audi services and repairs for drivers in the Louisville, KY area. Give us a call today to set up a convenient appointment!

Mini Coopers are fun, high-performing vehicles that are quite fuel efficient. Their unique design stands out to many drivers thinking of purchasing a cute, compact car. Minis require regular maintenance to keep them running properly. One common problem in the Mini Cooper is a bad PCV valve. It’s important to stay current on your maintenance schedule to extend the lifespan of your Mini’s PCV system.
The PCV system
The Positive Crankcase Ventilation (PCV) system is an emissions device with the purpose of moving excess gas out of the crankcase. The crankcase is an open space below your Mini Cooper’s cylinders. The PCV system removes gases and guides them to the intake manifold, where gas is burned.
Designed to get rid of unburned fuel being a problem, the PCV system’s function is essential to preventing damage inside of your car. Until the PCV system was developed, unburned fuel inside a car’s engine could leak, not only causing damage to the car’s inside but also creating pollution. The development of the PCV system created a way for unburned fuel to be directed back to the engine to reignite.
Symptoms of a Bad PCV Valve
If your PCV valve is failing, the excess gas won’t move to the intake manifold. Toxic gas is then left in the engine, where it can damage your car and possibly cause total engine failure. Your PCV system can fail due to two different causes: filter failure and valve failure.
When the Valve Gets Stuck or Fails
A stuck PCV valve can sometimes resemble symptoms of MAF failure. Some common symptoms that can occur if the PCV valve is stuck include the following:
- Rough idling
- Excess oil in the valve
- Engine not turning over or starting
- Low performance
- illuminated check engine light
- Black smoke from the tailpipe of your car
- Engine surging
- Excess oil consumption
Common symptoms of PCV valve failure are more serious and require immediate inspection and testing. These symptoms include:
- Leaking oil
- Gasket or seal failure
- An increase in internal engine pressure
- Engine misfiring
- Moisture beneath the hood of your car
- Oil in the MAF sensor
- Sludge buildup
- A contaminated filter
Replacement of the PCV Valve
The good news is that the PCV valve in your Mini Cooper likely will not fail if you stay regular on your car’s maintenance. The valve itself is a common item to repair and is usually replaced every 30,000 to 60,000, differing with models.
The main reason that PCV valves fail is a lack of maintenance. One thing you can do is stay current on changing the oil of your Mini. If you don’t, sludge could build up on the valve, which will clog it and then require a complete replacement. However, the PCV valve can also fail due to seemingly unrelated engine issues. This is another reason why it’s important to bring your car in for maintenance regularly, so mechanics can check your engine for any problems.
We recommend that you avoid driving your Mini Cooper when you know it has a faulty or failed PCV valve. This can result in severe damage as well as issues with performance that can make it difficult to drive in the first place. The best thing to do is take your car in to get inspected regularly to avoid frustrating and costly problems.

The front radiator support in a MINI is a key component of the vehicle’s cooling system. It helps to protect the radiator from damage and provides a mounting point for the fan assembly.
The front radiator support is made from sturdy materials that can withstand high temperatures and severe impacts. In addition, it is designed to channel airflow around the radiator and improve cooling efficiency. Without the front radiator support, the MINI would not be able to properly cool the engine and would be at risk of overheating.
Damage to the Front Radiator Support
The MINI is a popular vehicle for many drivers, but it’s important to be aware of the potential risks associated with this type of car. One potential issue is damage to the front radiator support. This can happen for a number of reasons, including:
- Poorly maintained roads: If the roads are in poor condition, they can cause the front suspension to bottom out, which can put stress on the radiator support and eventually lead to damage.
- Accidents: Unfortunately, accidents are always a risk when driving, and a collision can easily damage the front radiator support.
- Curb strikes: MINIs are notorious for having low ground clearance, which can make it easy to strike a curb and damage the front radiator support.
- Potholes: Another hazard of poorly maintained roads is potholes, which can also cause damage to the front radiator support.
- General wear and tear: Over time, even with proper care and maintenance, the front radiator support can weaken and become damaged.
If you drive a MINI, it’s important to be aware of these potential risks so that you can take steps to protect your car. For example, you may want to avoid driving on poorly maintained roads or be extra careful when parallel parking near curbs. If you do experience front radiator support damage, it’s important to get it repaired as soon as possible to avoid further issues.
Look for These Signs of Damage to the Front Radiator Support
Here are four signs that the front radiator support may be damaged:
- There is a visible dent or crumple in the metal.
- The paint is chipped or scratched in the area.
- The radiator itself is damaged or leaking.
- Your MINI refuses to start or stalls frequently.
- There is a visible gap between the engine and the frame.
- Your MINI’s engine seems to sit lower than usual.
- The front end of the vehicle appears to sag.
- There are cracks or holes in the radiator support.
If you notice any of these signs, it’s important to take your MINI to a qualified mechanic as soon as possible. They will be able to assess the damage and make any necessary repairs.
How We Will Fix It
If your MINI has suffered front radiator support damage, our mechanic will assess the extent of the damage and devise a repair plan. In some cases, the radiator can be simply unbolted and replaced.

Mercedes-Benz vehicles are known for their quality engineering and attention to detail, but one potential issue that can affect Mercedes-Benz vehicles is engine rattle. This problem is typically caused by loosened or damaged engine parts, and it can be quite unsettling for drivers.
If you notice any engine rattle in your Mercedes-Benz vehicle, it’s important to have the problem diagnosed and repaired as soon as possible. With prompt attention, you can help prevent further damage to your engine and keep your Mercedes-Benz running smoothly for years to come.
The Usual Suspects
There are several Mercedes parts that can cause this noise, and it’s important to identify the source of the problem so it can be fixed.
Exhaust Problems
One potential cause of engine rattle is a loose exhaust system. If the exhaust system is not properly secured, it can begin to vibrate and cause a rattling noise. The exhaust system is responsible for carrying waste gases away from the engine, and it consists of several metal parts that are held together with brackets and clamps. Over time, these parts can loosen and vibrate, causing a rattling sound. In some cases, the problem can be resolved by simply tightening the bolts or replacing the clamps. However, if the exhaust system is significantly damaged, it may need to be replaced altogether. Mercedes owners who are concerned about engine rattling should have their vehicle inspected by a qualified technician.
Motor Mounts
Another possible cause is worn out motor mounts. Over time, the rubber in the motor mounts can deteriorate, leading to excessive vibration and engine rattling. The noise is typically caused by the engine moving around too much in the engine bay. This can be caused by a number of things, including worn out motor mounts or an imbalanced engine. In some cases, Mercedes will replace the motor mounts under warranty. However, if the problem is not addressed, it can eventually lead to more serious damage, such as engine misalignment.
Ignition and Fuel Problems
Other problems include a bad ignition system or fuel system problems. When the ignition system is not working properly, it can cause the engine to misfire, resulting in a characteristic rattle. In addition to being annoying, this rattle can also indicate that the engine is not getting enough air, which can lead to further problems down the road.
Mercedes engines are designed to run smoothly and quietly. However, if the fuel system is not working properly, it can cause the engine to rattle. The fuel system is responsible for delivering fuel to the engine. If the fuel delivery is interrupted, it can cause the engine to misfire, which will cause a rattling noise. In addition, if the fuel pressure is too low, it can also cause the engine to rattle.
Heat Shield
In some cases, the rattling may be caused by something as simple as a loose heat shield. The heat shield is located between the engine and the firewall, and its purpose is to protect the engine from excessive heat. However, over time the heat shield can become damaged or detached, causing it to rattle every time the engine is running. This can be quite noisy and annoying, but more importantly it can cause damage to the engine over time.
If you’re hearing an engine rattle in your Mercedes, it’s important to have the problem diagnosed by a certified Mercedes technician. They will be able to identify the source of the problem and make the necessary repairs. Ignoring engine rattles can lead to further damage to your vehicle, so don’t delay in getting the problem fixed.

The BMW fuel pressure regulator is a vital component of the fuel system. It is responsible for regulating the pressure of the fuel that is delivered to the engine. The BMW fuel pressure regulator is located at the back of the engine, near the fuel tank. It is a metal cylinder with a black rubber hose attached to it.
The BMW fuel pressure regulator has two valves: one for the high-pressure side and one for the low-pressure side. The high-pressure valve regulates the pressure of the fuel that is delivered to the injectors. The low-pressure valve regulates the pressure of the fuel that is returned to the tank.
The fuel pressure regulator is controlled by a spring-loaded mechanism. When the engine is running, the fuel pressure regulator opens and closes the valves to maintain a constant pressure. If the fuel pressure regulator malfunctions, it can cause problems with starting the engine, idling, and acceleration.
Here are four signs that your BMW’s fuel pressure regulator (FPR) might be failing:
- The engine is running rough: If the fuel pressure is too low, the engine will run rough and misfire. Your BMW was designed to run with precision timing of its engine parts, so bring it in if you notice your engine isn’t running in top condition.
- The engine is hesitating: If the FPR is failing, the engine may hesitate or stall when you try to accelerate. This can cause a dangerous situation for you and your passengers. If you are merging with traffic or pull out in front of another car to cross the intersection, but your engine hesitates, this can cause a collision.
- The check engine light is on: A faulty FPR can trigger the check engine light on your dashboard since the engine will suffer if this part is not working as designed.
- You’re getting poor gas mileage: If the FPR is not working properly, fuel can leak into the engine, causing a loss of power and efficiency.
If you notice any of these symptoms, it’s important to have your BMW checked by a qualified mechanic as soon as possible. Ignoring a problem with the FPR can lead to more serious damage to your engine.
Cause for Concern
Fuel pressure regulators can fail for a variety of reasons. One common cause of failure is a build-up of deposits on the regulator itself. These deposits can come from a variety of sources, including dirt, debris, and even rust.
Another common cause of regulator failure is a sudden change in fuel pressure. This can happen if the vehicle’s fuel system is not properly maintained, or if there is a sudden drop in fuel pressure from the tank. In either case, it is important to have the BMW fuel pressure regulator serviced by a qualified technician as soon as possible.
How to Resolve It
If your BMW is experiencing fuel pressure regulator failure, our mechanic will hook up a fuel pressure gauge to the fuel valve. With the key in the ON position and the engine not running, they will observe the reading on the gauge. If it falls below or fluctuates above the specified range, then the regulator needs to be replaced. Our mechanic will then remove the old regulator and install a new one. Finally, they will recheck the pressure with the gauge to ensure that it is within the specified range. With our experienced mechanics, you can rest assured that your BMW will be running smoothly again in no time!

When shopping for a new car, many people put luxury brands like Audi at the top of their list. It’s easy to see why; Audi is known for its sleek design, powerful performance, and advanced features. But what are some of the other benefits of owning an Audi? For starters, Audi vehicles are built to last. They’re constructed with high-quality materials and undergo rigorous testing to ensure they can stand up to real-world conditions.
Despite all that testing, it is still possible that your Audi will experience problems in the future, especially common problems caused by wear and tear like an oil leak.
The Importance of Engine Oil to Your Audi
Engine oil is one of the most important fluids in your vehicle. It helps to lubricate engine parts, prevent corrosion, and remove heat. Without engine oil, your engine would quickly overheat and fail. That’s why it’s important to check your engine oil level regularly and top it off if necessary. It’s also important to choose the right engine oil for your vehicle. The type of oil you need depends on the make and model of your vehicle, as well as the climate you live in. It can even be affected by the type of driving you do, which is why it is important to have a good relationship with a mechanic you trust.
What causes oil leaks?
One of the most common causes of engine oil leaks is a faulty valve cover gasket. The valve cover gasket seals the space between the valve cover and the cylinder head, preventing oil from leaking out. Over time, the gasket can become cracked or brittle, allowing oil to seep through. In some cases, the gasket may even come loose, resulting in a more serious leak.
Another common cause of engine oil leaks is a worn or damaged oil pan gasket. The oil pan gasket seals the space between the oil pan and the engine block, preventing oil from leaking out. However, over time, the gasket can become dry and cracked, allowing oil to seep through. In some cases, the gasket may even come loose, resulting in a more serious leak. Lastly, a common cause of engine oil leaks is a bad seal on the crankshaft. The crankshaft seal seals the space between the crankshaft and the engine block, preventing oil from leaking out. However, over time, the seal can become dry and cracked, allowing oil to seep through. In some cases, the seal may even come loose, resulting in a more serious leak.
If you suspect that your engine has an oil leak, it is important to have it checked by a qualified mechanic as soon as possible. Oil leaks can lead to serious engine damage if left unrepaired.
Oil Leak Dangers
Car engine oil leaks are one of the most common types of mechanical issues that drivers face. An oil leak can cause serious engine damage, and it can also lead to a loss of power and efficiency. In some cases, oil leaks can even cause fires. Failure to fix an oil leak in a timely manner can thus be extremely dangerous. For this reason, it is important to be vigilant about checking for leaks and to take your car to a mechanic as soon as you notice any signs of a problem. By taking care of your car, you can help to avoid the dangers associated with an engine oil leak.
Routine Maintenance
Like many car issues, oil leaks can often be caught early or even prevented altogether by following a routine maintenance schedule. You should check your oil levels regularly between oil changes, and make sure to follow your mechanic’s recommended schedule for routine oil changes. You can also make sure you stay on top of all your other routine maintenance, as that can help prevent your engine from overheating which can cause oil leaks.

Driving your BMW with a shaky wheel is not only inconvenient but also hazardous. Such vibrations are signs of an underlying issue with your vehicle, and these issues must be addressed as soon as possible. Ignoring these signs would compromise both your comfort and the safety of all road users.
Unbalanced wheels, tire damage, broken rim, worn engine mounts, faulty wheel bearing, and loose lug nuts are the most prevalent reasons for a shaking wheel in a BMW.
Unbalanced wheels
Unbalanced wheels are the major reason why the wheel shakes or vibrates in BMW, especially while driving at high speeds. A driver feels the most vibration whenever the front wheel is out of balance. However, when the back wheel is out of balance, the vibration is felt throughout the entire vehicle.
- What causes out-of-balance BMW wheels?: An imbalance in your BMW’s wheels is frequently caused by uneven tire wear or impact by potholes or objects. This causes the rim and tire’s center of gravity to move unevenly around the axis. The wheel would begin to vibrate and the steering wheel would wobble as a result of the centrifugal force that happens at high speeds. This increases the wear and tear not just on the wheels, but also in other components.
- How are the wheels of BMW balanced? BMW wheels may be balanced using a specialized wheel balancer. The wheels are gripped and turned in the machine. Various sensors detect if the wheels are working smoothly or unevenly during rotation. If an imbalance is identified, tiny weights are attached to the rim to fix it. These compensate for the tire’s unequal weight distribution and guarantee that the wheel would run smoothly.
- How often should the tires of a BMW be balanced? There are no set intervals for balancing BMW tires; however, it is advised that you balance it with tire rotation every six months. Regular balancing not only lowers tire wear and eliminates costly vehicle damage, but it also improves driving comfort and safety.
Tire wear
One of the most prevalent reasons for a wobbly wheel is tire wear. You need to examine all of the tires in your BMW for cracks, bulges, cuts, and uneven wear. However, occasionally the damage to the tire is not immediately obvious, such as when the belt breaks within the tire, which can happen even with brand new tires. A crack or bulge in your tire’s sidewall indicates damage to the tire’s carcass or casing, which occurs when you drive over specific obstacles, such as deep potholes.
Damage to the rim
A bent rim might also lead to a shaky wheel in your BMW. This type of damage commonly happens when an impediment, such as a deep pothole or speed bump, is driven over too rapidly. Balancing the wheels is unlikely to solve the problem. A bent rim should be replaced.
Inspect the wheels carefully to check that the rims and spokes are not deformed or broken.
Even if no obvious damage is present, the entire rim may be bent, giving an uneven diameter. By installing the rim on the wheel balancing machine, a skilled technician can determine if it is bent.
Wheel bearing failure
A faulty wheel bearing in a BMW can cause wheel vibrations. The most typical symptoms of a faulty wheel bearing are a grinding sound in the cabin when going straight and a loud noise when cornering. It gets dangerous if you ignore the indications of a faulty wheel bearing and keep driving. In the worst-case situation, the damaged wheel locks up or tears off while driving.
Engine mounts that have deteriorated
The engine mounts of BMW are designed to keep the engine in place while minimizing vibration transmission to the car body. Engine mounts are constantly stressed because they are subjected to high pressures, intense vibrations, and environmental impacts. As a result, regardless of quality, they all wear down during use and eventually require replacement, usually after 5-10 years.
The most common technique to identify a faulty engine mount is by its symptoms. Visible vibrations on the body, steering wheel, or gear shift lever, even while the engine is idling, signal a major problem. Unusual sounds are also apparent indications of a faulty engine mount.
Loosen wheel nuts
Another apparent reason for wheel vibrations in your BMW is that the wheel lug nuts may have fallen loose or were not correctly tightened when changing tires. A lug wrench can be used to verify and rule out this problem.

Whether you notice a bulge in your tire when approaching your Mercedes in a parking lot or feel an odd vibration while driving, any time your tire is misshapen, there is a level of danger to not only you, but to your passengers and those driving around you. When you notice a bulging tire on your Mercedes in Louisville, it is important to have them checked by a professional as soon as possible. They will be able to determine the cause of the problem and make any necessary repairs. Trying to drive on bulging tires is extremely dangerous and should be avoided at all costs.
What Causes Bulging Tires?
There are several factors that can cause bulging tires, including overinflation, underinflation, excessive speed, hitting a curb or pothole, and even temperature changes. When a tire is overinflated, the air pressure inside the tire is greater than the pressure outside the tire. This can cause the tire to bulge outward. If a tire is underinflated, the opposite happens – the pressure inside the tire is lower than the pressure outside the tire. This can also cause the tire to bulge outward.
Excessive speed is another factor that can cause bulging tires. When a tire is spinning at a high rate of speed, centrifugal force causes the air inside the tire to expand. This can cause the tire to bulge outward. Hitting a curb or pothole can also cause bulging tires. When the tire hits something hard, it can be damaged internally. This damage can cause the tire to bulge outward.
Finally, temperature changes can also cause bulging tires. As the temperature outside decreases, the air pressure inside the tire decreases as well. This can cause the tire to bulge outward. Similarly, as the temperature outside increases, the air pressure inside the tire increases as well. This can also cause the tire to bulge outward.
The Dangers of Bulging Tires
Bulging tires are dangerous because they can lead to a blowout. When a tire blows out, the driver can lose control of the vehicle, which can lead to an accident. If you notice that your tires are starting to bulge, it’s important to have them checked by a professional as soon as possible.
Trying to drive on bulging tires is extremely dangerous and should be avoided at all costs, as a blowout could be dangerous to you, your passengers, and those on the road around you. Depending on the speed you’re driving at, the road conditions, and the traffic around you, a blown tire could easily turn into a major wreck. Driving on bulging tires is a risk not worth taking. So if you notice that your tires are starting to bulge, make sure to get them checked out by a professional ASAP.
How to Prevent Bulging Tires in a Mercedes
Bulging tires can be caused by a number of different things, but the most common cause is overinflation. When your Mercedes tire is overinflated, the air pressure inside the tire is greater than the pressure outside the tire. This can cause the tire to bulge outwards, either in one uniform shape or in bubble-like protrusions.
To prevent bulging tires, it’s important to check your tire pressure regularly and keep your tires inflated to the proper level. You should also avoid driving on rough roads or over potholes, as this can damage your tires and cause them to bulge. If you do hit a pothole or bumpy road, inspect your tires afterwards for any signs of damage.

The wheels in your Audi may have alignment problems if the car begins to pull to one side or make odd noises. If you hit a pothole or a curb at a relatively high impact, you may misalign that wheel, and your tire may squeal. If it is not such a violent misalignment, the tires can make an unusual humming sound as they are not gliding down the road properly and instead, gripping the road at an uneven angle. You know your Audi better than anyone. If you notice unusual sounds, bring it into our shop right away for an inspection. Let’s look closer into this issue.
Signs of a Poor Wheel Alignment
- Vehicle Pulling to a Particular Side: A vehicle having alignment issues will pull to one side, and it may squeal when cornering, even at low speeds. It is the most common and easiest sign to notice. When your Audi’s steering wheel is straight but you notice that your Audi pulls to one side, then it is certainly because of poor alignment.
- Off-Center Steering: Another common sign of improper alignment is when the steering wheel of your Audi is not aligned with the direction your car is moving. Your steering wheel may be tilted slightly to the left but your car is moving down the middle of the lane.
- Excessive tire wear in certain spots: If the tire of your Audi has worn excessively around the edge, then that is certainly a sign of poor alignment. The tires may have an odd humming sound as well. This occurs when the positive camber exerts pressure on the edge of the tower. It is commonly called camber or toe wear.
- The steering does not feel tight: Loose steering is caused by several problems such as a damaged or worn-out pitman’s arm, tie rod or ball joint, and bad wheel alignment. It is very unsafe to use your Audi with loose steering because it affects your ability to handle the car and maneuver it safely.
You may be tempted to ignore any of the signs above, and they may seem minimal; however, it is important you fix your Audi’s alignment issue immediately to avoid more damage to the tires and your Audi.
Misalignment in your Audi has a negative effect on your fuel economy, as your car needs to work harder, and thereby use up more fuel. Whenever you notice any of the signs of a poor alignment in your Audi, it is important to bring your car to our professional mechanics for proper alignment.
Types of Alignment
There are three types of alignment that can be done on your Audi car, and they include:
- Camber: This checks the wheel’s angle when looking at the car from the front. A positive camber occurs when the wheel tilts away from your Audi and vice versa.
- Toe: It occurs when the front wheel is aligned to the back wheel. When the front wheel points to the center it is a positive toe and vice versa.
- Caster: This is done by measuring the wheel’s pivot angle when looking straight from the car’s side. When the upper point of the wheel is tilted to the back, then it is a positive caster and vice versa. When there is a misaligned caster, your Audi’s steering would feel light and heavy.

Audi is popular among car lovers because it combines comfort, beauty, reliability, and good service with the latest car technology. Every component in the Audi brand is designed to endure. However, some external factors may cause some of these parts to become worse over time. If you desire your Audi to last for years, you need to pay attention to your vehicle and make routine maintenance a priority.
The catalytic converters help to reduce air pollution caused by the emission of harmful gases from the vehicle. It is usually found in the exhaust system. You will find it between the muffler and the engine.
The catalytic converter contains ceramic-coated beads and catalysts made from different precious metals. It works to convert harmful pollutants, such as nitrogen oxide and unburned gas, into harmless gases which can be released through the exhaust pipe into the environment.
Although the catalytic converter was designed to last for the full life cycle of a vehicle, it may become damaged and eventually fail.
Causes of Catalytic Converters Failure
- Bad spark plugs or spark plug wires: Bad spark plugs cause unburned fuel to enter into the exhaust system. The unburned fuel ignites in the hot catalytic converter and melts the catalysts inside the converter.
- Improper maintenance: When the engine of your Audi needs servicing but it is delayed, the by-product produced may spoil the catalytic converter. The wear and tear of the catalytic converter and the engine, as a result of the engine working outside its capacity, may cause the catalytic converter to fail.
- Malfunctioning Oxygen Sensor: Sometimes the oxygen sensor of your Audi may send inaccurate readings of the exhaust gases. This could cause the fuel mixture in your car to become either too lean or too rich. When it is too rich, the catalyst may melt because fuel is burning inside the converter. If it is too lean, the converter may be unable to convert hydrocarbons into harmless gases.
- Road / Structural Damage: Bad roads, road debris, and driving over speed bumps may have bad impacts underneath your car. This can affect the catalytic converter, causing the unit to crack. This would lead to restricted flow in the exhaust, causing an increase in backpressure in the exhaust system. Subsequently, heat is built up in the exhaust system which can also harm its parts.
- Driving short distances: When driving only short distances, the catalytic converter of your Audi might not get hot enough to burn the entire hydrocarbons inside it. This may lead to build-up, which eventually would clog the catalytic converter.
Catalytic Converter Failure Symptoms
There are several symptoms in a bad catalytic converter, and some of them are:
- Reduced performance of the engine
- Poor acceleration of the vehicle
- Emission of dark smoke from the exhaust, which smells like sulfur or bad eggs
- Excessive heating of the engine
- Engine’s warning illuminates
- Bad fuel efficiency
It is important that you don’t wait until you notice these problems before taking your Audi for routine maintenance. Regular maintenance can make the catalytic converter of your Audi last as long as it should, usually more than 10 years. It is also important that the exhaust and combustion systems of your Audi are working properly so that the catalytic converter would not fail before the normal time.
