2015 Mercedes-Benz Sprinter 2500

Reliability tier: verified - see /disclosure/

Engine: OM651 2.1L Twin-Turbo BlueTEC (Mercedes-Benz OM651, 2.1L)

2,143 cc I4, two-stage (bi-turbo) charging, Bosch common-rail piezo injectors. 161 hp @ 3,800 / 265 lb-ft @ 1,400 (Edmunds 2014 specs; MotorWeek/J.D. Power corroborate; one parts retailer lists 258 lb-ft and some period sources a 163 hp high-output tune on 3500 chassis-cabs - window 161-163 hp / 258-265 lb-ft across sources). 7-speed automatic. The BASE diesel of the facelift - the 3.0 V6 OM642 (mercedes-sprinter-om642) is the optional upgrade. No gasoline engine existed on US NCV3 facelift vans.

Applicable failure modes (7)

• Injector seal blow-by ('black death')

• EGR system: coking and cooler coolant leak

• Glow plug module and cold starts
• Intake port shutoff (swirl) flaps and motor
• Timing chain stretch (long-oil-interval related)

• OM651 Coolant Pump, parallel variant (651-200-17-02)

Platform recipes (3)

• Catch-it-early injector reseal: the copper seal blows by, combustion gas cokes around the injector ('black death')
• BlueTEC DEF/SCR derate on the 2.1 (2014-2018): diagnosis chain first - DEF quality and level sensing, then the supply pump, tank last
• EGR coking and swirl-flap service on the 2.1: EGR soot jams the port shutoff flaps (P2017-family codes) and cokes the valve/cooler
