How to Troubleshoot Engine Problems on an Audi 80?

I'm having trouble starting my Audi 80 and there is a strange noise coming from the engine area. What should I do to diagnose and fix this issue?

Check your battery and make sure it's fully charged. Sometimes a dead battery can cause the engine not to start and produce strange noises. If the battery is fine, then it's best to consult a professional mechanic for a proper diagnosis and repair.

Inspect the spark plugs and wires for any damage or wear. These components are crucial for the engine to run smoothly and if they are faulty, it can cause starting and performance issues. Replace any damaged parts as necessary.
