🚨 What to check before buying
Overall risk score: 9/10
Serious risks
- Injector seal bolt rounding: Injector seal bolts can round off during removal. Requires specialist extraction. Budget for this at service.
- Timing chain stretch (early units): Early OM651 can develop chain stretch and rattling at higher mileage.
- Alternator decoupler pulley: Alternator clutch pulley wears out, causing squealing noise and eventual alternator bearing failure.
- EGR cooler leak: EGR cooler can crack internally, causing coolant loss and white smoke.
- Diesel injector seal leak: Black residue around injectors indicates seal leak. Can cause rough running.
- Car is 11 years old — some age-related maintenance expected (seals, suspension components)
Additional notes
- Any car with 200k+ km requires extra scrutiny. At this mileage: suspension components are worn (bushings, ball joints, shocks), seals and gaskets are hardened, electrical connectors corrode, and major components approach end-of-life. For luxury cars (BMW, Mercedes, Audi) the cost of 200k+ km maintenance can exceed the car's value. Always get a pre-purchase inspection (PPI) and budget 15-25% of purchase price for immediate maintenance.
- Diesel car from before 2018 with very low mileage suggests city-only use — DPF is likely clogged or has been removed (illegal). Check DPF status and EGR condition.
