2 known faults with sources

OM654/OM656 AdBlue, DPF and EGRAdBlue / DPF / EGR

Engine / equipment: OM654 2.0 and OM656 3.0 diesel (C, E, S, GLC, GLE, GLS, G-Class from 2016)
Period mentioned: 2016–2026
Symptoms: AdBlue or emissions warnings with a start countdown; particulate filter warning; power loss or rough idle from a dirty EGR.
Possible cause described: These are robust engines; faults concentrate in the emissions system. The AdBlue system (injector, NOx sensors and SCR catalyst) sometimes fails, especially in the cold, and the particulate filter and EGR foul if the car mostly does short trips.
Check for the garage: Read AdBlue and NOx sensor codes with Xentry, check the particulate filter regeneration history and how the car is used (short trips).
Cost cited in the source: AdBlue system: approx. €500–1,200; particulate filter: €1,000–2,000A rough figure from the original database, not an up-to-date quote.

Mileage cited in the database: from 100,000 km. This is not a maintenance interval and does not predict a failure.

Period mentioned: 2014 onwards
Symptoms: A knock from the rear axle of unclear origin, cabin rattles, air conditioning and auxiliary heater that do not always work and phone-connection problems.

Check for the garage: Check every campaign by VIN; test the air conditioning and the auxiliary heater.
