Known weak points
- Timing chain sprocket wear on the camshaft adjuster (OM646), causing rattling noise and a check engine light
- Wiring harness insulation near the engine/transmission degrading and becoming sticky, causing electrical faults
- Turbocharger wear leading to smoke and loss of power if oil changes are neglected
- Glow plug and glow plug relay failure causing hard cold starts
- EGR valve clogging with soot on later OM646 engines, causing rough idle
- Injector seal leaks causing hard starting and a diesel smell at idle
