How to troubleshoot a faulty starter motor in an Audi A2?

I've noticed that my Audi A2 is having trouble starting up. Sometimes, it takes multiple attempts to get the engine running. I suspect it might be an issue with the starter motor. Can anyone provide some guidance on how to troubleshoot and fix this issue?

If you think it could be the starter motor, the first thing to check is the connections. Make sure they are clean and tight to ensure a good connection and proper function.

If the connections are fine, the next step would be to test the starter motor itself. You can do this by using a voltmeter to check the voltage at the starter motor when attempting to start the car.
