What is the most common cause of oil leaks in Audi A4?

I have been experiencing frequent oil leaks in my Audi A4. I have noticed puddles of oil under my car when parked and a drop in oil levels. What could be causing this issue and how can I fix it?

The most common cause of oil leaks in Audi A4 is a faulty valve cover gasket. Over time, the gasket can deteriorate and cause oil to leak out. It is recommended to have it replaced by a certified mechanic.

Another potential cause of oil leaks is a damaged oil pan or oil drain plug. If the pan or plug is cracked or worn, oil can leak out. It is important to have it inspected and replaced if necessary.
