Tip: If there are drips after the test drive as shown (Figure 3) you should be able to determine if the leak is from the ATF sump gasket or if the leak is from elsewhere. Make sure to check for leaks above the sump gasket. Check the seam of the transmission case split and the weep hole of the double seal (Figure 4). Both of these leaks can be confused for an ATF sump gasket leak.

Tip: If the ATF sump gasket has been diagnosed to be leaking after all the above checks, replace the ATF sump gasket according to the Repair Manual and recheck for leaks. Use Warranty Table 2 if the ATF sump gasket is replaced. If the repair manual is followed using the special tools, the required wheel alignment should not be necessary.
Note:
If the oil leak is not from the ATF sump gasket please open an Audi Technical Assistance contact with the pictures of the leak attached to the ticket and contact Audi Technical Assistance for repair authorization.
