Known issues and risks
Listed from most frequently reported, each with its source.
SCR / AdBlue / NOx sensor failures
Often reported
The exhaust after-treatment system (AdBlue injection, SCR module, NOx sensors) can cause issues: out-of-tolerance sensors, clogged AdBlue injectors or fluid crystallization, uncounted counters, and dashboard messages requiring diagnosis.
Exhaust Emissions
DPF clogging
Often reported
The 2.0 diesel engine (OM654 family) has a DPF with automatic regeneration. In predominantly city driving or short trips, regeneration may not complete, leading to particulate filter clogging; this results in dashboard warnings, power loss, and regeneration issues.
Exhaust Emissions
Injection system sensitivity and operating anomalies
Often reported
The modern common rail system (and in some variants, piezo injectors) is sensitive to fuel quality and maintenance. Irregular operation, power loss, or faults requiring injector or circuit intervention are reported.
Fuel System
Turbocharger failures or damage
Often reported
In four-cylinder OM654 versions, turbocharger-related performance loss or abnormal noises are reported.
