Known Issues

M272 Engine Timing Chain Sprockets:

Early M272 engines (prior to ~2007 but can sometimes affect early W212 derivatives) had issues with timing chain sprocket wear leading to timing deviations. The 2011 model year largely uses the improved M276 engine, mitigating this.

Om651 Diesel Injectors:

Some reports of injector issues, particularly in earlier OM651 variants, requiring specialized diagnostic and replacement procedures.

Suspension Components:

Wear on control arm bushings and ball joints can occur with mileage, impacting ride quality and alignment.

7G Tronic Mechatronics:

Occasional electronic module (mechatronic unit) issues can arise, affecting shifting performance.
