Campaign No. 2011030004, April 2011
TO: ALL MERCEDES-BENZ CENTERS
SUBJECT: Model 212, Model Year 2011
Check Vibration Damper, Replace if Necessary
This Recall Campaign has been initiated because Daimler AG, the manufacturer of Mercedes-Benz vehicles, has determined a possible inconsistency
during the vulcanization process at the supplier for the vibration damper located on the engine. This can lead to insufficient adhesion between the
vibration damper and its inner mass damper ring, which may cause a sudden separation of the inner ring from the vibration damper without prior
warning. As a result, the kinetic energy of a separated mass damper ring can create a potential for personal injury when working in the engine
compartment while the engine is running. Dealers will check for a production date and replace the vibration damper if necessary.
Attached is a sample copy of a letter which owners of the affected vehicles will receive.
Prior to performing this Recall Campaign:
^ Please check VMI to determine if the vehicle is involved in the Campaign and if it has been previously repaired.
^ Please review the entire Recall Campaign bulletin and follow the repair procedure exactly as described.
Please note that Recall and Service Campaigns do not expire and may also be performed on a vehicle with a vehicle status indicator.
Approximately 41 vehicles are involved.
Procedure
1. Check production date (first 3 digits) on bar code affixed to vibration damper:
Turn the engine in normal rotation until the bar code sticker (arrow, Figure 1) affixed to the vibration damper is visible:
^
If the first 3 digits are not 167 (circled, Figure 1): procedure is complete.
^
If the first 3 digits are 167 (circled, Figure 1): proceed to next step.
2. Replace vibration damper, refer to WIS: AR03.30-P-1600EWS.
