Frequently Asked Questions

Is my W251 R280 CDI covered regardless of wheelbase?

Yes. The manual covers the W251 chassis in both standard and extended long-wheelbase configurations produced during the 2007–2009 model years, including left- and right-hand-drive variants.

Does coverage include the OM642 swirl flap issue — one of the most common R280 CDI failures?

Absolutely. The intake manifold section provides factory-correct procedures for diagnosing and replacing the OM642 swirl flap actuator assembly, which is a well-documented failure point on this engine family.

Are wiring diagrams and electrical diagnostics included?

Yes. Full circuit diagrams are provided covering engine management (CDI), 7G-TRONIC controls, ABS/ESP, AIRMATIC suspension, climate control, and central locking — with connector pinouts, wire color codes, and component locations.
