Frequently Asked Questions
Is the OM651 timing chain issue documented in this manual?
Yes. The OM651 balance shaft and timing chain tensioner failures are well-documented problems across the Mercedes diesel lineup. This software includes the complete replacement procedure, torque values, and special tool requirements needed to address this repair correctly on the CLS250 CDI.
Does the C218 platform share components with other Mercedes models?
Yes — the C218 CLS-Class shares its platform architecture with the W212 E-Class. Many suspension, driveline, and electrical components are shared across both model lines, which is reflected in the overlapping service procedures within this software.
Are wiring diagrams and COMAND system diagnostics included?
Full electrical documentation is included, covering the CAN-bus network, engine management circuits, BlueEfficiency system wiring, COMAND infotainment schematics, climate control circuits, and all body electronics. Connector pinouts and component locations are clearly identified throughout.
What format is the manual?
This product is dealer workshop software — not a PDF. It runs on Windows (XP through 11), Mac, and Linux, and features menu-driven navigation, search by engine code or gearbox code, zoom-in diagrams, and thousands of photographs. An active internet connection is not required after installation.
