Topic number
LI27.00-P-056643
Version
1
Design group
27.00 General
Date
07-12-2013
Validity
Vehicles with OM651 and TRANSMISSION 722.9
Reason for change
Cause and remedy revised.
Reason for block
Complaint:
During disengagement from D to N and/or from R to N some slight jolting could be experienced.
Cause:
Due to the idle speed (up to 845 rpm depending on model), the drivetrain can become slightly stressed with mode D
or R engaged. When disengaging to N, the stress in the drivetrain is released, which can be felt as a slight jolt under
certain circumstances.
Remedy:
An adaptation of the disengagement process is not possible because disengagement is purely mechanically controlled and there is no electrical involvement.
Please do not replace any components because this is a comfort-related complaint only. It is impossible for any components to be damaged by this.
You will be notified of any updates via a subsequent LI.
