Frequently Asked Questions
Is the OM651 timing chain covered, and how serious is this issue?
Yes. The OM651 2.1L diesel used in the C250d has a documented history of balance shaft module and timing chain tensioner wear, particularly on higher-mileage units. This software includes the complete factory repair sequence for timing component inspection, tensioner replacement, and balance shaft module service, along with torque specifications and special tool requirements.

Are interactive wiring diagrams included for the COMAND and body control modules?
Yes. The software provides complete circuit diagrams for every electrical system, including the COMAND infotainment unit, instrument cluster, all body control modules, lighting, and engine management. Component locators identify exact sensor, relay, and ground point positions, and connector pin assignments are fully documented.
