What is causing the oil leak in my Audi 80?

I've noticed a small puddle of oil under my Audi 80 whenever I park it. What could be the possible cause of this leak and how can I fix it?

It could be a faulty oil filter or drain plug. Check these components first and replace them if necessary. You can also inspect the oil pan and gasket for any cracks or damage.

It is possible that the oil leak is coming from a worn out seal or gasket in the engine. Have a mechanic check the seals and replace them if needed.

Make sure to also check the oil pan for any dents or damage that may be causing the leak. If there are any issues, consider replacing the oil pan.
