How can I troubleshoot a faulty starter in an Audi 80?

I recently noticed that my Audi 80 was having trouble starting up, and after some research, I think it might be an issue with the starter. However, I'm not sure how to approach fixing it. Has anyone experienced this issue before and have any insight on troubleshooting and fixing a faulty starter?

First, try checking the electrical connections to the starter for any loose or corroded connections. If everything looks good there, you may need to replace the starter itself.
