When buying a used Mercedes-Benz GLE 350d 4MATIC G-TRONIC 2022, the most frequently mentioned issue is: SCR/AdBlue system and NOx sensor faults. Additionally, DPF clogging and incomplete regenerations are also commonly reported.
Be cautious
Most reported issue: SCR/AdBlue system and NOx sensor faults. Service history and a test drive matter.
Listed from most frequently reported, each with its source.
The complex SCR (AdBlue dosing) system and related NOx sensors can cause errors or faults in the 2.0 diesel version: dosing errors, out-of-tolerance sensors, or urea injector nozzle failures can trigger dashboard warning lights, power restrictions, or require intervention.
Exhaust Emissions
In the 2.0 diesel OM654 engine of the 300 d (269 HP) version, DPF clogging can occur, especially with city driving and short distances. Passive regenerations often fail, and forced regeneration or professional cleaning may be required.
Exhaust Emissions
In the 2.0 OM654 engine, the EGR valve and actuators can accumulate soot and carbon; this can lead to faults, the engine warning light coming on, and performance loss. In some cases, mechanical actuators fail or stick, requiring deep cleaning or replacement.
Exhaust Emissions
In the 2.0 OM654 engine, issues with the injection system, including piezo injectors and the high-pressure network, have been reported. Symptoms include rough running and power loss; intervention may be required on the pump or injectors. These components are sensitive to fuel quality.
