Reliability snapshot
The first X1 (E84) is a compact crossover built on the rear-drive-based E90 platform. Common items are the timing chain on the N47 diesel and early N20 petrol, plus plastic cooling components and the electric water pump on six-cylinder cars. It is generally durable for a compact BMW; the main attention points are the timing-chain concern on the affected engines and routine cooling maintenance.
