How to troubleshoot a faulty ignition in an Audi 80?

I've noticed that my Audi 80's ignition seems to be failing. It takes a few attempts to start the car and sometimes it stalls while running. What could be causing this issue and how can I fix it?

The most common cause of a faulty ignition in an Audi 80 is a worn out ignition switch. It's recommended to have it replaced by a professional mechanic to ensure proper functionality and safety.

Another possible cause could be a malfunctioning starter solenoid. This component is responsible for sending power from the battery to the starter motor. Have it checked and replaced if necessary.
