Campaign - Rear SAM Module Replacement

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

Campaign No. 2005100009, November 2005

TO: ALL MERCEDES-BENZ CENTERS

SUBJECT:
MODEL 211, MODEL YEAR 2003
INSPECT REAR SAM CONTROL MODULE, REPLACE IF NECESSARY

This Service Campaign has been initiated because DCAG has determined that on the affected vehicles (see VIN range) a fault in the rear signal acquisition and actuation module (rear SAM) may under some circumstances cause the fuel gauge to no longer register the proper fuel level if the battery is disconnected. The dealer will check the rear SAM for the affected part number with Star Diagnosis, and when identified, replace it with an updated unit.

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 19,046 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.
