Frequently Asked Questions

Is the OM651 timing chain issue covered in this manual?

Yes. The OM651 2.1L diesel used in the SLC 250d has a documented history of balance shaft sprocket and timing chain tensioner wear. The software includes full engine disassembly procedures, timing chain replacement torque specifications, and special tooling requirements to properly address this repair.

Is the SLC 250d the same platform as the SLK?

Correct. The SLC Class replaced the SLK Class in 2016, both riding the R172 platform. The SLC 250d is mechanically related to the SLK 250 CDI, sharing the OM651 diesel engine family and the same two-seat roadster body structure with retractable hardtop.

Are wiring diagrams and CAN-bus diagnostics included?

Yes. The software provides complete electrical schematics including engine management, fuel injection, lighting, climate control, and body electronics. CAN-bus network topology, connector pinouts, wire color codes, and sensor testing specs are all included to support thorough electrical fault diagnosis.

What format is the manual?

This is dealer workshop software, not a PDF. After downloading, you install the interactive program on a Windows PC (or Mac/Linux via compatibility layer). It features searchable procedures, zoomable diagrams, and fault-finding flowcharts – the same toolset Mercedes-Benz technicians use at franchised dealerships.
