Of course, once you notice any of these common issues if you own an Audi, get in touch with our team, specializing in German auto repair for your elite vehicle.
Burning Oil Smell and Oil Leaks
Audi engines typically leak from the tensioner gasket seals or the valve covers. Leaking oil can be a potential fire hazard and if you can smell the oil burning, it is best to get the issue fixed quickly. The smell is created by oil hitting the exhaust and burning while you drive.
Leaking oil can also be a danger to the electronics in your Audi.
The electronics can also be affected by an Audi leaking oil. It can permeate the wiring and cause damage to the control modules and electrical connections. The longer your oil leaks, the higher the likelihood that your repair is going to become more expensive. Additionally, the longer it continues, the less oil you have running through your engine, so it is important to address this issue quickly.
Clicking or Clunking during a Sharp Turn
Usually, this is one of the known problems with Audis that is the result of overlooking a needed repair on your axle CV boot. When the CV boot tears, the grease is expelled and the joint begins to wear out as a result of the lack of lubrication. Eventually, the entire axle assembly may need to be replaced. If you have a torn CV boot, get it replaced quickly to avoid a more extensive problem and repair.
If your Audi sounds throaty when you accelerate, you may have an exhaust leak. A number of Audi models have a flexible joint between the catalytic converters and the downpipe in the exhaust. This joint is prone to leaking. While a deeper exhaust may sound cool, an extended leaking exhaust can become quite expensive.
If you suspect you have an exhaust leak, call us at Shaus Motorsport. We can determine the best next steps for fixing one of the known problems with Audis.
Check Engine Light with a Rough Running Engine
If your engine is running rough and your check engine light has come on, you may have a cylinder that is misfiring. It is possible that your ignition coil is the source of this problem. In fact, your Audi may have been part of a recall for ignition coils. Your local repair shop can help you determine if your ignition coil needs to be replaced.
Check Engine Light is on, but Your Audi Sounds Great
If your check engine light stays on for multiple cycles and your Audi seems to be running fine, the trouble could be an emissions related issue. To figure out what’s causing your check engine light to come on, you need to bring your Audi in so we can provide a deeper analysis and locate the source of the problem. There are a number potential areas to look into, all related to known problems with Audis.
Low Coolant Light is on or Coolant Leaks
Your make frequently have trouble with the low coolant light coming on as Audis commonly have visible coolant leaks. The culprit could be a crack in the coolant reservoir. Sometimes, the leak can be difficult to find because the coolant will evaporate upon reaching the exhaust component. Thankfully, replacing the coolant reservoir is generally inexpensive when the repair is taken care of before the problem progresses.
Turn Signals Don’t Work or Stay On Continually
In older models, this is one of the known problems with Audis. Frequently, the source of this problem is the hazard switch. Additionally, it could be related to a faulty switch in the steering column. This cause is not nearly as likely though.
During a cold start of your vehicle, you may hear a rattle or knocking noise. This can be caused by an Audi’s camshaft adjuster or the camshaft chain tensioner. If this is the case, the noise will last for a second or two after the car starts. This noise can be normal on a particularly cold day. If it lasts for more than a couple seconds, the problem will need a more detailed diagnosis to determine the nature of the issue.
Unpleasant Odors from Ventilation and Heating System
If a musty odor is coming from your heating system, you may have an issue with mold in the ducts. The mold and the odor can be removed, however, repeated, regular treatments will be necessary to keep the mold from returning.
Turbo Car Blowing Smoke
If your turbo vehicle is blowing smoke, you need to have an Audi-trained mechanic look at it right away. There are a number of simple reasons for the smoke, but getting it taken care of is a must to avoid a much more expensive repair. The worst-case scenario could be a failing or worn out turbo. Oil may be passing by the turbo and heading down the exhaust creating the smoke. If it is not taken care of quickly, the oil can destroy your catalytic converter and this will cause your repair to be much more costly.
You can remove the intercooler hose and if more than just a small amount of oil runs out of the hose, you have an issue that needs prompt attention.
Trunk Won’t Automatically Close
A voltage distribution module failure is another of the known problems with Audis, and it’s one of those odd electrical issues like a truck that won’t close automatically or an MMI that opens or closes randomly. When the voltage distribution model is not working properly, various devices in your Audi will either exhibit strange behavior or fail to work. It is also possible that your vehicle’s battery needs to be replaced.
