Topic number

Version

Design group
07.08 Control modules
Date
06-16-2014
Validity
Model 222 and 166 with engine 278
Reason for change
The ME - engine control unit software update for model
GL450 MY 2014 is not presently available
Reason for block
Complaint:
Engine diagnosis warning lamp (check engine light - CEL) lights up in instrument cluster.
Fault codes relating to combustion misfiring are logged in the fault memory of the engine control unit.
In rare cases the engine may be in a limp-home mode. Otherwise there are no other engine performance issues.
Cause:
Combustion misfire detection with unfavorable combination of combustion data assignments and component tolerances.
Remedy:
1.
If other faults concerning the ignition, fuel supply or wiring harness contacts are present in addition to the faults
relating to combustion misfiring, then these must be processed first and general misfiring causes must be considered as well.
2.
Check the fault freeze frame data of the combustion misfires in relation to time of occurrence after engine start
and coolant temperature (injector performance data might be also used as a reference).
3.
If the time of occurrence is less than 120 seconds after engine start and at the same time the coolant temperature is below 45°C, please proceed as follows:
- S550 (model series W222): Update the software of the engine control unit. It is no longer necessary to replace
injector(s) on this model and this complaint.
- GL550 (model series X166 - 166.873): Update the software of the engine control unit. It is no longer necessary
to replace injector(s) on this model and this complaint.
- GL450 (model series X166 - 166.872): Replace injector(s) of the cylinder(s) logging the fault (the engine control unit software update is not available at this time for this model).
Note: All available add-on must be installed on the Xentry Diagnostics unit.
