Alright guys im new to this forum and this is my first porst. i recently purchased a 2002 a6 2.7l Biturbo Quattro and i discovered now that i have a leak.
I know that im on the a4 part of the forum but im desperate.

There wasnt any oil on the ground and my oil was normal on the dipstick but the plastic tray underneath was dreanched in oil. The oil is in front of the oil pan and plug and so I guess that its not the problem and i can cancel out the oil pan gasket. IDK am I right on that?
I am 17 and have somewhat knowledge on cars and how to work on them. I plan on removing the covers tommorow but have any of you had this problem and if so where was the leak? any info would be much appreciated thanks
