Reliability, common problems and owner reviews for the Bmw X2 sDrive18d / 20d / xDrive20d (B47). Check this before you buy used.
The 2.0 diesel (B47 — the engine that replaced the chain-troubled N47, shared across the 1/2-Series and X1) is the high-mileage X2 choice: torquey, very economical and built on a more robust timing-chain arrangement than the N47 it superseded. Standard modern-diesel cautions remain: DPF and EGR on short trips (the EGR cooler is a known weak point), injector and timing-chain attention at high miles, and AdBlue. A motorway-driven, serviced car is a dependable long-hauler — the engine for the miles. Buy on EGR, DPF and AdBlue history.
