Campaign No. 2008120011, January 2009
TO: ALL MERCEDES-BENZ CENTERS
SUBJECT:
Models 164/164.8/251 Model Year 2008
Replace Power Steering Rack
This Recall Campaign has been initiated because Daimler AG has determined that a defect may exist in the driving pin used to control the oil pressure of the power steering. This defect resulted from a manufacturing process flaw at the supplier. If a defective driving pin exists in a vehicle and the pin breaks during normal vehicle turning, the normally available hydraulic support function will no longer function and steering wheel operation will be limited. The dealer will check VIN lists and date codes and replace the power steering rack, if necessary, at the next workshop visit.
Shown in this bulletin is 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 577 vehicles are involved.
