Frequently Asked Questions
Why does my R-Class AIRMATIC suspension sag overnight, and does the manual cover the fix?
Sagging air suspension on the W251 R-Class is typically caused by a leaking AIRMATIC strut or a failing compressor. The manual includes complete strut removal and installation procedures, compressor output testing, ride-height sensor adjustment values, and the torque specs required to complete the repair correctly.
Which chassis code does this manual cover, and are both wheelbase lengths included?
Yes — this manual covers the W251 platform in its entirety, encompassing both the standard and extended (long-wheelbase) body configurations sold in the US from the 2007 through 2017 model years, including the R280, R300, R350, R500, and R63 AMG variants.
Are the OM642 diesel engine’s EGR and swirl flap procedures documented?
Full coverage is provided for the OM642 3.0L V6 CDI, including EGR valve cleaning, swirl flap actuator replacement, DPF regeneration cycles, and injection system specifications — all common service items on US-market R320 CDI and R350 BlueTEC models.
