Frequently Asked Questions
What is the known swirl flap issue on the OM642, and does this manual cover the fix?
Yes. The OM642 3.0L V6 diesel used in the R280 CDI is known for swirl flap actuator failure — broken plastic arms can drop into the intake, causing serious engine damage. This manual covers full intake manifold removal, swirl flap assembly inspection, and replacement procedures with torque specs.
Which chassis code does this manual apply to?
This manual covers the W251 chassis, which underpins the R-Class in both standard and extended long-wheelbase body configurations sold in the US and globally between 2007 and 2009.
Are CAN-bus and 4Matic electrical diagnostics included?

What format is the manual?
This is a dealer-level software manual, not a PDF. It runs on Windows, Mac, and Linux and features menu-driven navigation, zoom-in diagrams, and integrated wiring schematics — the same tool used by Mercedes-Benz approved workshops.
