SUBJECT:

Model 906, Model Years 2010 -2011
Update Engine Control Module Software

This Service Campaign has been initiated because Daimler AG (DAG), the manufacturer of MercedesBenz and Freightliner Sprinter vehicles, has determined that humidity can enter the exhaust gas
recirculation (EGR) valve which may cause an electrical short circuit. As a result, the feedback signal from
the valve to the engine control module (ECM) may fail. As a consequence, the EGR valve may be
switched-off and the vehicles will experience a loss of power and enter a limp home mode. In addition,
certain software parameters in the ECM may not respond properly to brief control deviations of the EGR
valve position. Under certain circumstances, this ECM programming can cause an unfavorable response
which can deactivate the periodic cleaning function of the EGR valve. If the control deviation occurs twice
within two consecutive driving cycles the MIL will be illuminated. To correct these conditions, Dealers will
update the Engine Control Module software at the next workshop visit.

Prior to performing this Service Campaign:
•

Please check VMI to determine if the vehicle is involved in the Campaign and if it has been previously

•

Please review the entire Service 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 23, 122 vehicles are affected.

adaptations I Control module programming

3.

Perform programming of CDI control module: Control units I Drive I CDI 6 common rail injection I Control
unit adaptations I Control module programming.

4.

Follow on-screen instructions.

5.

Check fault memory: If fault memory16CEOO and/or 16CFOO is present, delete it by pressing the F9
button.

Note:
•
