Historical MOT pass rates and DVLA records for 2018 model year cars.
- Water Pump / Thermostat LeaksModerate
Later petrol and diesel engines still suffer coolant leaks from pumps or plastic thermostat housings.
- AdBlue SCR System NOx Sensor & Tank Heater FailureSerious
On 2.0 TDI and 3.0 TDI diesel models, failing downstream NOx sensors or crystallized AdBlue dosing injectors trigger a persistent dashboard no-restart countdown.
