What are the common issues to look out for in an Audi 80 engine?

I recently purchased a used Audi 80, and I want to know what potential engine problems to keep an eye on. The car has over 100,000 miles on it, and I want to ensure its longevity.

One common issue with Audi 80 engines is the timing belt. It is important to check the belt regularly and replace it when necessary to avoid engine damage.

Another potential issue to keep an eye on is the cooling system. Leaks or malfunctions in this system could lead to engine overheating and potential damage. Regular maintenance and checks can prevent this.
