Recall - ECM Update for E85 Fuel Usage
Campaign No. 2007040005
May 2007
TO: ALL MERCEDES-BENZ CENTERS
SUBJECT:
MODEL 203.052
MODEL YEAR:
2007
CHECK ENGINE CONTROL MODULE SOFTWARE AND UPDATE AS REQUIRED
This Recall Campaign has been initiated because DCAG has determined that on affected vehicles the software for the engine control module may need to
be updated regarding fuel type for Flex Fuel Vehicles. Vehicles without the engine control module software update that are filled only with E85 fuel may
experience starting problems, rough vehicle operation and "Check Engine" lamp illumination. Dealers will update the engine control module software as
required.
Prior to performing this Recall Campaign:
-
Please check VMI to insure the vehicle is involved in the Campaign and if it has been previously repaired.
Note:
Do not perform Recall Campaign P-RC-2007040006 in addition to or in place of this Recall Campaign.
