All about the BMW X4 (F26)All about the 3.0d (BMW N57) engine
The 3.0d (BMW N57) engine was fitted to the BMW X4 (F26) (2014–2018). In the EU that is 26.3 % of all new cars of this generation.
Versions: 3.0 258 hp, 3.0 313 hp, 3.0.
The most expensive known risk is main and big-end bearing damage (low oil pressure at idle): it usually appears at 150,000–250,000 km and costs €3,000–7,000 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: Knocking from the bottom of the engine, metal particles in the oil, oil pressure warning only when damage is already done
Fix: Keep oil changes short (about 10,000-15,000 km) with LL-04 oil; at the first knock stop driving and have the bearings and oil pump checked
Signs: Metallic rattle or scraping from the back of the engine, mostly at cold start or low revs
Fix: Check chain stretch with diagnostics at the first noise; replace chain, guides and tensioner (usually engine out); keep oil intervals short
Signs: Swirl flap fault codes, rough running or power loss; a broken flap can enter a cylinder and damage the engine
Fix: Inspect and clean the intake manifold at high mileage; replace the manifold or flaps if they are sticking or loose
Signs: Often none; coolant loss without a visible leak, white smoke when accelerating or a burning smell
Fix: Have a BMW dealer check by VIN whether the recall was done; the EGR cooler is checked and replaced free of charge
Signs: Power loss, rough idle, smoke, EGR fault codes; worse with short trips
Fix: Clean or replace the EGR valve and clean the intake manifold
Signs: DPF warning, frequent or failed regenerations, limp mode
Fix: Check the differential pressure sensor first, then forced regeneration, cleaning or replacement
Signs: Oil smell, oil sweating on the engine
Fix: Replace the leaking gasket
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.
