Platform recipes (3)
- BlueTEC DEF/SCR derate (2010+): the countdown is a diagnosis chain, not a parts verdict - DEF quality and level sensing first, then the supply pump, tank hardware last (the big bill)
- Diagnosis-driven EGR/intake service: clean before you replace
- The signature OM642 repair: the oil-to-coolant stack sits deep in the V of the banks, so the intake and ancillaries come off for access
