Transmission Symptom - Oil Leaks on Automatic Transmission: Observe Specified
Procedure (SY 205/20)
Model Line:
Cayenne (9YA/9YB)
Model Year:
As of 2018
Concerns:
Automatic transmission
Symptom:
Oil leaks are found on the vehicle in the area of the automatic transmission. The location and cause of the
problem cannot always be clearly determined.
Background:
We have discovered that the location and cause could not always be clearly determined in the dealer
organization when attempting to resolve the complaint “Oil leak”. As a result, some of the repair
measures that were carried out were not always effective.
An oil-contaminated oil pan, for example, may also be caused by oil migrating from the threaded
connection on the oil line.
Information
Oil leaks on the transfer box are described in the document  Technical Information 'Transmission
symptom - Oil leaks on transfer box: Observe specified procedure (SY 206/20)'.
Remedial
Action:
Find oil leaks and carry out the relevant repair measure.
Preparatory work
Work
Procedure:
Information
•
Oil leaks must be clearly identifiable and reproducible.
•
Engine oil and coolant must have reached operating temperature during a test drive.
1
Document the original complaint condition with meaningful photos.
2
Attach documentation to PQIS line.
3
Clean automatic transmission and transfer box thoroughly.

Information
If the oil leak has spread so that the oil pan is also
contaminated  Oil migration, proceed as follows in
the event of a complaint:
• Check that the screws on the ATF pan are
accessible and are seated correctly with the
specified tightening torque and secure properly if
necessary.
• Clean the area of the ATF pan extremely thoroughly
as oil penetration of the ATF pan seal can result in
incorrect interpretation.
4
Spray large areas of the automatic transmission and
transfer box with SpotCheck around the suspected
leakage points.
5
Perform a test drive.
6
Locate the oil leak:
•
•
•
Oil migration
The oil leak is located on the transfer box, continue with  Technical Information 'Transmission
symptom - Oil leaks on transfer box: Observe specified procedure (SY 206/20)'
The oil leak is located on the automatic transmission, continue with  Technical Information 'Oil
leaks on automatic transmission'.
The oil leak cannot be clearly identified, continue with  Technical Information 'Oil leaks on
automatic transmission'.
7
Produce photo documentation of the leakage point located using SpotCheck.
8
Attach documentation to PQIS line.
Oil leaks on automatic transmission
Information
Traces of oil on the ATF pan can occur as a result of oil migration.
Only in rare cases is the ATF pan seal defective.
1
Check for oil leaks on the underside of the ATF pan  Crack in ATF pan.
If a crack is discovered, replace the ATF pan, see  Technical Information 'Replacing ATF pan'.
