Historical MOT pass rates and DVLA records for 2018 model year cars.
- OM651 Diesel Chain Tensioner Oil LeakModerate
On 1.8-litre and 2.1-litre OM651 diesel engines, the timing chain tensioner seal is a well-documented weak point. Over time the rubber O-ring gasket degrades, leading to persistent engine oil weeping down the right flank of the engine block. Left unaddressed, loss of oil pressure at the tensioner can cause timing chain rattle on startup and premature stretch.
- DCT gearbox judder and clutch wearModerate
The 7G-DCT dual-clutch transmission (Getrag/Mercedes 724.0) suffers from low-speed lurching, clutch shudder, and software calibration drift, particularly on cars driven primarily in stop-start urban traffic. Neglecting the mandatory 4-year/40,000-mile transmission fluid and dual-filter service accelerates clutch pack wear and mechatronic solenoid sticking.
- M270 Petrol Timing Chain StretchSerious
The 1.6-litre and 2.0-litre M270 turbocharged four-cylinder petrol engines can experience timing chain elongation and tensioner fatigue, especially when subject to extended variable service intervals. An elongated chain causes camshaft timing deviation, triggering check engine warnings and in severe cases skipping teeth.
