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 and collect ATF from the all-wheel drive coupling 1.
• 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.
• Check that the S-tronic transmission/manual transmission is at operating temperature.
• Let the vehicle cool down.
• Check that the S-tronic transmission/manual transmission is at operating temperature.
• 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.
• Check that the S-tronic transmission/manual transmission is at operating temperature.
• 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  .
