Frequently Asked Questions

Is the GL450 known for balance shaft gear problems in the M273 V8?

Yes. The M273 4.7L V8 fitted to the X164 GL450 has a documented balance shaft gear wear issue, particularly on pre-facelift 2006-2009 models. Early gears used a plastic/composite construction that could deteriorate, leading to timing noise and potential engine damage. This software includes full timing chain and balance shaft inspection and replacement procedures with factory torque specs.

Does this cover both the pre-facelift (2006-2009) and facelift (2010-2012) GL450?

Yes. All seven model years of the X164 GL450 are included – pre-facelift and post-facelift variants alike. Region-specific specifications for North American market vehicles are incorporated throughout, and the software allows searching by model year, sales market, engine code, and gearbox code.

Are interactive wiring diagrams included for the COMAND and Airmatic systems?

Absolutely. The dealer software provides dynamic, interactive wiring diagrams covering the full CAN-bus network, COMAND infotainment, Airmatic air suspension controls, parking assist, lighting circuits, and all body control modules. Diagrams include connector pinouts, wire colors, and component location data – far beyond what a static schematic provides.

What format is the manual?
