Audi A6 2.0 TDI 2012 Problems
Are Audi A6 reliable?
They are, but there are a few common issues that owners have reported, such as airbag problems, high oil consumption, defective electrical system, excess vibration, injector failure, or diesel particulate filter.
Here are some of the most common faults that have been reported.
Airbag Issues
Airbag issues can pose a significant threat to vehicle safety, and unfortunately, this is a fault status Audi A6 2.0 TDI 2012 owners may face.
The airbag system is designed to protect the occupants in the event of a collision, but when there is a problem with the system, it may not function properly.
Some owners have reported issues with the airbag warning light staying on, which may indicate something’s wrong with the system.
A faulty oxygen sensor, poor wiring, or severe damage to the airbag module are just a few possible causes for this problem.
Faulty Electrical System
The electrical system is responsible for powering various components, such as lights, radios, and other electrical devices.
Still, as complaints from Audi A6 owners, the instrument panel’s fault code warning of “Electrical System Malfunction” and the yellow or red battery symbol is frequently brought up.
An Audi A6 electrical system malfunction will trigger issues with these gears and may even cause the vehicle to fail to start.
Some of the symptoms of a defective electrical system are flickering/dim lights, difficult start-ups with the faulty engine block, or a dead battery.

High Oil Consumption
The 2.0-liter diesel engine in this vehicle is known for consuming oil at a higher rate than usual, which equals more frequent oil changes and increased costs for the owner.
In some cases, this issue may also lead to mechanical damage if the oil level is not maintained properly.
The cause of the high oil consumption is not entirely clear, but it may be related to the design of the piston rings and cylinder walls in the rotary engine.
To prevent this issue, it is important to maintain the oil level and have the vehicle inspected by a qualified mechanic regularly.
Vibrating Problems
Vibrating Audi A6 problems are another issue that some owners have reported.
These vibrations can occur at highway speeds or while driving normally, and may be felt through the steering wheel or the entire vehicle.
The cause of these vibrations can vary, but it may be related to the suspension system or wheel alignment.
The suspension system is responsible for keeping the vehicle stable and absorbing shocks from the road, and when there is a problem with the system, vibrations are inevitable.
Additionally, if the wheels are not aligned properly, it can cause uneven wear on the tires and lead to excessive shaking.
Injector Failure
The fuel line injectors are responsible for delivering fuel to the compact diesel engine; when they fail, it entails a range of problems.
Some symptoms of injector premature failure include a rough idle, engine power loss, and poor fuel economy.
This issue can be caused by various factors, including clogging the injector nozzles or wear and tear of the injector components.
Plus, the injectors can also prematurely fail, which is a very often reported problem. It goes without saying that this causes the DCi engine to operate poorly or not start at all.
Diesel Particulate Filter Issues
Diesel particulate filter issues are also among the problems some Audi A6 2.0 TDI 2012 owners have reported.
The DPF (diesel particulate filter is responsible for filtering out particulate matter from exhaust gas, which helps to reduce emissions.
But, over time, the oil filter can get clogged with soot and other debris, which can cause a range of problems.
Some signs of a blocked DPF include unexpected engine failure, excessive fuel consumption, and a warning light on the dashboard.
