FILE:
SERVICE: GROUP 00 OF SERVICE INFORMATION BINDER
PARTS: GROUP I OF INFORMATION _ PARTS & ACCESSORIES BINDER

TO: ALL MERCEDES-BENZ CENTERS

SUBJECT:
MODELS 164, 209, 211, 219, 221, 230, 251, X164

MODEL YEAR 2007

CHECK TRANSMISSION CONTROL MODULE SOFTWARE AND UPDATE IF NECESSARY (722.9 TRANSMISSION); UPDATE ENGINE CONTROL MODULE SOFTWARE AS REQUIRED (M273 ENGINE)

This Service Campaign has been initiated because DCAG has determined that on affected vehicles (see VIN range on the following page) the software for the transmission control module may need to be updated to adjust the lock up force of the torque converter. The engine control module software will also be updated. Dealers will update the transmission control module software and the engine control module software as required.

Please review the Effective Serial Number chart located on the following page, and if necessary, repair the subject vehicles during the vehicle's next service.

Prior to performing this Service Campaign:
- Please check VMI to insure the vehicle is involved and to determine if the vehicle has been previously repaired.
- Please review the entire Service Campaign bulletin.

Approximately 27,691 vehicles are affected.

Effective Serial Number Range

NOTE:
Every vehicle in the VIN range may not be included in the campaign. VMI must always be checked before performing campaigns to verify that the campaign is required on a specific vehicle. VMI always overrides the bulletin in reference to a specific vehicle's inclusion in a particular campaign. Please also note that Recall and Service Campaigns do not expire and may also be performed on a vehicle with a vehicle status indicator.
