2015 Mercedes-Benz Sprinter 3500

Reliability tier: verified - see /disclosure/

Engine: OM642 3.0L V6 BlueTEC (Mercedes-Benz OM642, 3.0L)

72-degree V6 turbodiesel, 188 hp / 325 lb-ft in this era, 7-speed automatic. NCV3 facelift: the 2.1L OM651 twin-turbo became the BASE diesel - the 3.0 V6 is the optional/upgraded engine on this config (engine code disambiguates the two diesels). 188 hp / 325 lb-ft, 7-speed automatic from the facelift.

• Glow plug module and cold-start roughness
• Intake port shutoff (swirl) flap motor and stuck flaps
• Oil cooler stack seal leak (the signature OM642 repair)

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
