How can I troubleshoot a problem with the timing belt on my Audi 80?

I've noticed some strange sounds coming from my car and upon further inspection, I suspect it may be an issue with the timing belt. How can I diagnose and fix this problem on my Audi 80?

First, check the condition of the timing belt for any signs of wear or damage. If it looks worn or frayed, it's likely time for a replacement. For more accurate diagnosis, use a timing light to check the alignment of the cam and crankshaft. If the timing marks don't line up correctly, it's a sign of a faulty timing belt. As for fixing the issue, it's best to take your car to a professional mechanic to ensure it's done properly and prevent any further damage.
