Audi A6 Common Problems and Solutions
Gearbox problems
Problem:
If you notice that gear changes are very hesitant or clunky when driving around town in an automatic, CVT, or multitronic gearbox, it is known that these gearboxes can have software problems.
Solution:
You will need to take the car to an Audi dealer to have the software reprogrammed, which should resolve this issue. If the car is under warranty, it will be repaired free of charge; otherwise, it is your responsibility to arrange the repair.

Turbo problems
Problem:
Sometimes, turbos on these vehicles can fail. If you notice blue smoke coming from the exhaust, or if you hear a whistling noise from the top of the engine, this indicates that the turbo is failing.
Solution:
You will need to fit a replacement turbo to resolve the issue.

Excessive oil use
Problem:
The A6 is known for consuming a lot of oil. If the oil level drops too low, it can have damaging effects on the engine.
Solution:
You should regularly check the engine's oil levels by ensuring the dipstick reads at least halfway between the Min and Max marks. You may need to top up the oil if the levels are too low.
Difficulty level
Water leaking into passenger foot well
Problem:
If water is leaking into the passenger footwell, it is usually caused by a blockage in the drainage holes below the windscreen or in the plenum chamber. Leaves and debris can block these drainage holes, leading to water entering the passenger footwell. The plenum chamber is where the air conditioning system takes its air from. When the drains in that chamber become blocked with water, it will leak into the footwell.
Solution:
You need to inspect these areas and unblock the drainage holes to prevent water leaking into the passenger footwell. You should also dry out the carpets and mats to avoid odours or dampness. Check out the video below.
Difficulty level
Excessive vibration from 2.0L engine
Problem:
If you can hear a loud vibration from the engine when you rev it in neutral, this is typically caused by an issue with the dual mass flywheel.
Solution:
This is a very costly repair, and your best option is to have a professional examine it for you. You can save money by buying a quality second-hand flywheel with us.
