Historical MOT pass rates and DVLA records for 2015 model year cars.
- Steering Rack RattleModerate
The EPS rack can develop internal play, often cured with the BMW thrust-piece kit but sometimes needing a complete rack.
- N20 Timing Chain Guide FailureSerious
Early four-cylinder petrol cars use plastic timing-chain guides that can fail, often signalled by a supercharger-like whine before the chain jumps.
- EGR Cooler Leak (Diesel)Serious
Leaking coolant in the diesel EGR system can mix with soot and create a fire risk (Recall 18V755). UK recall completion matters more than a seller saying it has been checked.
