Chassis Context
The 2002 Sprinter T1N (Freightliner/Dodge) uses the original T1N Sprinter chassis — sold in North America as a Freightliner or Dodge Sprinter rather than a Mercedes-Benz. The powertrain is an OM612 (2002–2003) or OM647 (2004–2006) 2.7L inline-5 turbodiesel paired with a NAG1 5-speed automatic. Critically, the T1N has no DEF/AdBlue system, no DPF, and no SCR catalyst, so emissions-related faults common on later Sprinters simply don't apply here. What does apply: the bulkhead harness chafing recall, turbo resonator plastic cracking, swirl flap carbon buildup, brake-booster vacuum pump leaks, and the "black death" injector seal failures unique to this era.
