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

I have noticed some oil spots underneath my Audi 80, and I want to know what could be causing them. I also want to know if I can fix the issue myself or if I need to take it to a mechanic.

The most common cause of oil leaks in an Audi 80 is a faulty gasket or seal in the engine. Other possible causes include worn out piston rings or a damaged oil filter. It is important to address the issue as soon as possible to avoid further damage to your engine.

In some cases, an oil leak can be caused by a loose or damaged oil drain plug. Check this first before assuming a bigger issue with your engine. If the plug is loose or damaged, it can easily be replaced.

If you notice a burning smell along with the oil leak, it could be a sign of a leak in the valve cover gasket or a leak in the exhaust system. These issues should be addressed by a mechanic as they require specialized tools and knowledge to fix.
