All about the BMW X4 (F26)All about the 1.6d / 2.0d (BMW N47) engine
The 1.6d / 2.0d (BMW N47) engine was fitted to the BMW X4 (F26) (2014–2018). In the EU that is 32.2 % of all new cars of this generation.
The most expensive known risk is timing chain stretch at the gearbox end (worst on 2007-2011 builds): it usually appears at 80,000–220,000 km and costs €2,000–4,500 to fix.
✓ The faults of this engine were checked against sources (10/2026). Each item has at least two independent sources or an official recall or parts-maker technical note.
Signs: Rattle or whirring from the back of the engine, mostly after a cold start or around 1,500-2,000 rpm; later cam/crank correlation faults (P0016/P0017) and possible chain breakage
Fix: Do not keep driving at the first rattle; replace chains, guides, tensioner and sprockets with the latest revised parts (engine or gearbox must come out); short oil change intervals help
Signs: Swirl flap fault codes, uneven running or power loss; a broken flap or screw can enter a cylinder and damage the valves, piston or turbo
Fix: Inspect the intake manifold from about 150,000 km; clean it or fit a new manifold with flaps
Signs: Often none; coolant loss without a visible leak, white smoke or a burning smell; in rare cases the plastic intake melts
Fix: Have a BMW dealer check by VIN whether the recall was done; the EGR cooler is replaced free of charge
Signs: Power loss, jerky part-load running, EGR fault codes (e.g. P0401), soot in the intake
Fix: Check EGR valve and bypass flap with vacuum hoses; clean or replace the valve, replace cracked hoses
Signs: DPF warning, frequent or failed regenerations, limp mode (e.g. P2002); worse with short trips
Fix: First check the differential pressure sensor, its hoses and the thermostat; then forced regeneration, cleaning (if ash is high but the core is intact) or replacement; use LL-04 oil
Signs: Rough idle, knocking, smoke, hard cold starts; injector correction values out of range
Fix: Read injector quantity corrections and do a leak-off test to find the faulty one; recondition or replace only the faulty injectors
Signs: Shimmy under braking
Fix: Replace bushes / arms
Signs: Harsh ride; expensive to replace
Fix: Budget accordingly
Signs: 4x4 / DSC warning lights, grinding
Fix: Replace actuator motor / gear
Signs: Slipping, high bite point
Fix: Replace clutch kit
Signs: Rattle at idle, vibration pulling away
Fix: Replace with clutch
Typical routine maintenance cost for 100,000 km: €2,650–6,350. Sum of the services and wear parts in the plan above (about 15,000 km a year, independent workshop), without faults.
