What is the most common issue for faulty ignition in Audi 80 models?

I noticed my car's ignition is not functioning properly, and I suspect it may be a common issue with Audi 80 models. What could be causing this problem and what steps should I take to resolve it?

It is a known issue with Audi 80 models that the ignition switch may fail due to wear and tear over time. It is recommended to have the ignition switch replaced by a certified mechanic to ensure proper functioning.

Another potential cause could be a worn out ignition cylinder, which can be replaced rather than the entire ignition switch. It is important to address this issue promptly to avoid any potential safety hazards.

In addition to the ignition switch and cylinder, it is also important to check the ignition coil, spark plugs, and battery. These components are critical for proper ignition functioning and should be periodically inspected and replaced if necessary.
