TECHNICAL BACKGROUND 1
Due to the different speeds between the front axle differential and the rear final drive, varying degrees of humming, droning, vibrations, or rubbing can occur when taking very tight corners, driving in a straight line (especially on wet roads), and when the all-wheel drive coupling 1 is closed.
PRODUCTION SOLUTION
Not applicable.
SERVICE
Try to reproduce the customer concern (based on the description/workshop findings/event memory entries), so that it can be clearly assigned to this Technical Service Bulletin. The following repair must only be carried out if all the criteria (model/type, chassis number, engine/gearbox code, PR number(s), part number, software version, code etc.) apply exactly. Otherwise, this measure will not eliminate the problem, and repeat repairs may be necessary. In such a case, we may reject warranty claim and charge back the cost of parts.
Complete the repair in the following order:
- Check that the S-tronic transmission/manual transmission is at operating temperature.
- Completely drain off ATF from the all-wheel drive coupling 1 and dispose of the ATF properly.
- Add new ATF according to the repair manual (part number G 055 515 A2) and then set the ATF level according to the repair manual.
- Reach or confirm operating temperature in the S-tronic transmission/manual transmission.
- Let the vehicle cool down.
- Reach or confirm operating temperature in the S-tronic transmission/manual transmission again.
- Completely drain off ATF from all-wheel drive coupling 1 again and dispose of the ATF properly.
- Add new ATF according to the repair manual (part number G 055 515 A2) and then set the ATF level according to the repair manual.
- Reach or confirm operating temperature in the S-tronic transmission/manual transmission again.
- Let the vehicle cool down.
- Perform the basic setting "Reset learnt values for oil ageing" using ODIS Guided Functions or Self Diagnosis, All-Wheel Drive Electronics (address 0022) >> Control Module Functions >> Basic Settings >> Reset learnt values for oil ageing.
- Drive the vehicle (maximum 60 miles) until the customer complaint is no longer present.
