- OM651 Diesel Chain Tensioner Oil LeakModerate
The gasket on the timing chain tensioner can fail, leaking oil and potentially leading to timing chain issues due to inconsistent tension.
- Rear Subframe CorrosionSerious
The rear subframe rots from the inside out, leading to MOT failure. Mercedes often replaces these under goodwill.
- Electronic Steering Lock (ESL) failureSerious
The electronic steering lock module can fail, preventing the car from starting. The key is recognised but the steering remains locked. A common and expensive fault on W204s built before the facelift.
