Engine varies by trim; verify the engine code on the listing.
Listed from most frequently reported, each with its source.
Some vehicles with the OM654 engine control unit report non-start conditions due to electrical issues related to fuses (e.g., blown F152 fuse) or faults requiring intervention in the control unit.
Electrical
The complex exhaust after-treatment system (SCR + AdBlue dosing + NOx sensors) can develop issues such as out-of-tolerance NOx sensors, AdBlue dosing problems, or selective catalytic component failures.
Exhaust Emissions
In the OM654 2.0 diesel, the DPF can clog, especially with city or short-distance driving. Automatic regenerations may not complete, causing warning lights, power loss, and the need for forced regeneration.
Exhaust Emissions
The EGR system in the OM654 engine can accumulate carbon deposits that clog the actuator or passage channels, especially with city driving and short trips. A clogged or faulty EGR valve manifests as a check engine light, rough running, and performance loss.
Exhaust Emissions
The modern common-rail system and injectors, particularly the piezoelectric versions used in the OM654 engine, can be sensitive to fuel quality and may cause rough running, power loss, or faults requiring intervention.
