How do I fix the ignition system in my Audi 80?

I've been having trouble starting my Audi 80 and I suspect it's due to a faulty ignition system. Can anyone offer some advice on how to fix this issue?

First, check the battery and make sure it is fully charged. If that's not the issue, try cleaning the spark plugs or replacing them if necessary. It's also a good idea to check the ignition coil and ignition switch. If all else fails, take your car to a certified mechanic for a diagnostic test and potential repairs.
