How do I diagnose and fix engine oil leaks in an Audi 80?

I've noticed that my Audi 80 is leaking engine oil and I want to fix the issue myself. What steps should I take to identify where the leak is coming from and how can I fix it?

The first step is to identify where the oil is leaking from. Check the oil pan, valve cover gasket, and oil filter for any cracks or damage. Also, make sure all connections and fittings are secure and not leaking. Once you have identified the source of the leak, you can then proceed to fix it.
