What are the common causes of oil leaks in Audi 80 models?

I am experiencing oil leaks in my Audi 80 and it is causing concern. I have recently had my oil changed and it seems to be leaking much more than before. Any ideas on what the issue could be and how to fix it?

The most common cause of oil leaks in Audi 80 models is a faulty oil filter. Make sure to check if it is installed correctly and replace if necessary. Also, inspect the oil pan gasket for any damage or wear.

Another potential cause of oil leaks in Audi 80 models is a worn out valve cover gasket. It is recommended to replace the gasket every 50,000 miles to avoid leaks. Also, check the valve cover bolts and replace if necessary.

If the oil leak is coming from the oil drain plug, it may be loose or damaged. Make sure to tighten the plug properly or replace it if it is damaged. Also, check the oil drain plug gasket for any wear.
