^ Repair Code 10 deleted
^ Reimbursement Procedure added

Enclosed is a sample copy of a letter which will be mailed in the near future to all owners of vehicles within the Effective Serial Number Range listed below.

This campaign has been initiated because MBAG has determined that if the headlamp washer system is activated with the headlamp wiper arm misaligned (i.e. headlamp wiper arm does not return to a horizontal park position) or lodged in the groove below the headlamp unit, the headlamp washer pump will run continuously expelling all available headlamp washer fluid and possibly leading to a vehicle fire.

WARNING!
Headlamp washer pump operation without the presence of washer fluid can cause the headlamp washer pump to overheat and cause a vehicle fire.
A modified headlamp washer pump has been designed.

Therefore, on vehicles within the chassis end number range given in the Effective Serial Number Range table on page 2, the headlamp washer pump must be replaced with the modified headlamp washer pump.

Additionally, any customers whose vehicle falls within the chassis end number range given who have had the headlamp washer pump replaced at their expense on a prior repair, can request reimbursement. These vehicles must be checked regardless. to verify installation of the modified headlamp washer pump, part number 129 869 00 21 (embossed on the headlamp washer pump housing).
Please see W.I. 360A, page 5 for details.
