Production Solution
Improved assembly procedure.

Service
If the reported oil leak appears to be from the ATF sump area proceed with diagnosis and repair as follows:
1. Take photos of the actual condition and attach to the Repair Order.
2. Retighten the ATF sump
bolts with a torque of 5
Nm. Make sure to follow
the correct tightening
sequence (Figure 1).

Figure 1. Tightening sequence.
3. Clean the sump and transmission thoroughly with brake clean and make sure the transmission and sump are
dry before proceeding.

4. Apply oil leak detection
spray (Part # G 001 900
A1 or a locally available
talcum-based oil leak
detection spray
equivalent) to the sealing
area of the sump, ATF
cooler, drain plug, and
the case half seam
(Figure 2).

Figure 2: Transmission with oil leak detection spray applied.
5. Test drive the vehicle and reassess the oil leak after the test drive.
6. If there is no further leaking the condition is repaired. Use Claim Warranty Table 1 for this repair.

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.
