How to diagnose and fix a faulty starter in an Audi 80?

I have a 1997 Audi 80 and lately, it has been having trouble starting. The engine cranks but does not start. I suspect it could be a faulty starter, but I am not sure how to confirm and fix it. What could be causing this issue and how can I diagnose and fix it?

Firstly, make sure to check the battery and the connections to ensure proper voltage is being supplied to the starter. If that is not the problem, it could be a faulty starter solenoid or a wiring issue. It may be best to consult a professional mechanic for further diagnosis and repair.

One possible cause for a faulty starter could be a worn out or damaged starter motor. It may be worth getting it tested at an auto parts store or replacing it altogether if needed. Also, check for any damage or loose connections in the wiring leading to the starter.
