Turbocharger for Mercedes Benz GL320,GL350,ML320,ML350 (2007-2013) 3.0L

Direct-Fit Replacement Turbocharger for 2007-2013 Mercedes Benz GL-Class,M-Class (W164 / X164)

What it Does: The direct-replacement turbocharger replaces degraded factory units on 2007-2013 GL-Class and M-Class diesel vehicles to restore factory boost levels, eliminate electronic actuator limp-mode faults, and recover low-end torque.

The Stock Mercedes Benz GL-Class,M-Class OM642 Turbocharger Failure Points

The factory Garrett variable-nozzle turbine (VNT) setup on the OM642 3.0L diesel frequently suffers from severe soot and carbon buildup. Exhaust particulate accumulates inside the turbine housing, binding the variable vane mechanism and overworking the electronic stepper actuator. This mechanical drag causes internal actuator gear stripping and solder trace fracture from extreme engine valley heat soak, triggering P0299 underboost codes and limp-home mode. Concurrently, thermal coking in the oil passages accelerates journal bearing wear, leading to oil blow-by past the dynamic seals into the intercooler tract.

The Engineering Solution

Engineered to exact OEM tolerances, this complete turbocharger assembly features high-temperature alloy turbine housing and a cast aluminum compressor wheel balanced dynamically at high speeds to prevent shaft deflection. It comes pre-fitted with a calibrated electronic rotary actuator that syncs with factory ECU vane positioning protocols without recalibration. High-grade journal bearings and heavy-duty thrust collars resist axial loading and endure sustained exhaust gas temperatures (EGTs) during diesel particulate filter (DPF) regeneration cycles, preventing oil bypass and restoring crisp throttle response.

Frequently Asked Questions & Fitment Warnings

Does this fit the W164 / X164 GL-Class,M-Class?

Yes, this is a direct fit for the 2007-2013 Mercedes Benz GL-Class,M-Class equipped with the OM642 3.0L Turbo Diesel engine. It does not fit gasoline-powered M272 or M276 V6 applications.

What mechanical procedure is required before installing this turbocharger?

You must flush or replace the oil feed and return lines, clean the intake charge piping, and perform an engine oil and filter change to avoid particulate contamination of the new bearings.
