Hi everyone... Iíve been working on a 2007 Audi a8 4.2. I had to replace the tailshaft and transfer cover case. After refilling the transmission with fluid, Im getting a leak out of a tiny hole in the bottom of the transmission (see pics). The hole is located right in front of the tailshaft and in the transfer case. The hole is about a 1/2 of an inch and goes up into the transmission about 4-5 inches. At the top of the hole is a pin hole where the leak is coming from. It is part of the transmission but I have no idea why it is leaking. It will leak about 2 tablespoons of fluid a night out of the hole onto the ground. Any idea? Do you think I overfilled the transmission? I called the service department and they have never heard of this hole and really did not understand what i was talking about.

Edit:

Sorry, had a blond moment... didn't read the part about the hole being at the bottom of the tranny.

Did you ever figure out what this was? Was it a seal or an overfill that caused the issue?
