- CVT / clutch actuator wearSerious
Automatic W169s can suffer worn clutch actuators or CVT issues.
- Timing chain stretch and tensioner wearSerious
Petrol M266 engines can suffer from timing chain stretch and tensioner failure, leading to a rattling noise on cold start. If left unchecked, the chain can jump and cause catastrophic engine damage.
- Injector seal and fuel system faultsModerate
Diesel CDI models can develop leaking injector seals, leading to the "black death" — a build-up of carbon and fuel residue around the injectors that can damage wiring and the cylinder head.
