How to troubleshoot a failing starter motor in an Audi 80?

My Audi 80 is having issues starting and I suspect it may be due to a failing starter motor. What are some steps I can take to diagnose and fix this problem?

First, make sure the battery is fully charged and the connections are clean. If that doesn't fix the issue, check the connections between the starter motor and the battery. You may also want to try giving the starter motor a tap with a hammer to see if that helps it engage.

If the above steps don’t work, it’s possible that the starter motor itself is faulty and needs to be replaced. In this case, I would recommend taking your Audi to a trusted mechanic for further diagnosis and repair.

Another potential cause of starting issues in Audi 80s is a faulty ignition switch. This can cause the starter motor to not receive power and thus fail to start the engine. To check for this, try turning the key in the ignition to multiple positions and see if the starter engages.
