Historical MOT pass rates and DVLA records for 2014 model year cars.
- OM651 Diesel Chain Tensioner Oil LeakModerate
The gasket on the timing chain tensioner is a frequent source of oil leaks. This can lead to decreased oil pressure for the tensioner, causing chain rattle.
- Rear Subframe CorrosionSerious
Like the W204, the rear subframe can corrode badly enough to fail an MOT and require full replacement.
- NOx Sensor and AdBlue FaultsModerate
BlueTEC diesels regularly trigger engine lights, limp mode or restart countdowns when sensors or heaters fail.
