What is the best way to troubleshoot starter issues on an Audi 80?

My Audi 80 is having trouble starting and I suspect it may be an issue with the starter. I'm looking for any tips or advice on how to troubleshoot and fix this problem.

First, check the battery and ensure it has enough charge to turn over the engine. If the battery is fine, then the issue may be with the starter motor. Check for any visible damage or corrosion, and try tapping it gently to see if that helps. It could also be a problem with the ignition switch or wiring. If all else fails, it's always best to take it to a certified mechanic for further diagnosis and repair.

Before assuming it's a starter issue, make sure to rule out any other potential causes such as fuel delivery problems or a faulty spark plug. If those seem fine, then it's worth checking the connections and wires going to the starter to ensure everything is securely in place. If the starter still seems to be the problem, try jumping it with another vehicle to see if that helps.
