How do I troubleshoot a faulty ignition switch in an Audi 80?

I've been having trouble starting my Audi 80 and suspect it may be due to a faulty ignition switch. What are the steps I can take to troubleshoot and fix this issue?

First, try cleaning the ignition switch with contact cleaner and see if that improves the functionality. If not, you may need to replace the switch entirely. In both cases, make sure to disconnect the car battery before working on the switch to avoid any safety hazards.

Check the connections between the ignition switch and the starter. Loose or corroded connections can lead to issues with starting the car. If you find any issues, fix and reconnect them to see if that solves the problem.

If the above steps don't work, it may be a good idea to take your Audi 80 to a certified mechanic. They will have the necessary tools and expertise to accurately diagnose and fix any issues with the ignition switch.
