-
✔ X4 xDrive28i-Specific Timing Chain Solutions
We replace the N20B20A timing chain tensioner (OEM 11318608935) with upgraded guides that address the specific stretch pattern unique to the xDrive28i's elevated mounting angle and oil starvation during F26 chassis cornering loads.
-
✔ B48B20A Cooling System Upgrades
Our reconditioned engines include the revised auxiliary water pump (OEM 11517632425) that prevents the specific F26 engine-bay heat soak failures affecting 2018-2020 xDrive28i models, a fault not seen in saloon applications of the same engine.
-
✔ N20B20A High-Pressure Fuel Pump Fix
We fit the updated HPFP (OEM 13517616156) with revised sealing rings that cure the xDrive28i's unique cold-start misfire caused by the F26's inclined fuel-tank pick-up and differing evaporative-emission calibration versus the 3 Series.
-
✔ Twin-Scroll Turbocharger Rebuild
Every xDrive28i engine gets a turbocharger reconditioned with upgraded wastegate bushings (OEM 11657613824) to stop the specific 1.2-bar over-boost condition that triggers 30FF fault codes on 2014-2017 F26 models during motorway inclines.
-
✔ F26 Engine-Mount Reinforcement
We reinforce the aluminium front sub-frame mount points (OEM 31126852371) that crack on xDrive28i units due to the higher centre of gravity and increased torsional stress unique to the X4's coupe-SUV body versus the F25 X3.
-
✔ BMW Service Bulletin Compliance
Our rebuild follows BMW SI B11 09 15 that addresses valvetronic servo-motor failure in N20/B48 engines; for the xDrive28i we also install the F26-specific heat shield (OEM 51757419033) missing in the original recall.
-
✔ 24-Month F26 UK Warranty
Coverage includes the xDrive28i's unique all-wheel-drive transfer-case oil cooler (OEM 27107572255) and front driveshaft seals - components excluded by standard warranties because the X4's torque-vectoring calibration increases fluid temperatures.
Rated 4.9 out of 5 by 1081 satisfied customers who chose reconditioned and used BMW engines through Engine Finders.
Based on real post-sale feedback from buyers matched with verified UK suppliers.

BMW X4 xDrive28i Replacement Engines
Launched in 2014 on the F26 platform, the X4 xDrive28i brought BMW’s 2.0-litre TwinPower turbo to a coupe-SUV package. Early cars (2014-2016) used the N20B20A, notorious for timing-chain guide wear (BMW bulletin B11 01 15) exacerbated by the X4’s steeper oil-pan angle during spirited cornering. The 2017 facelift introduced the B48B20A, gaining a redesigned chain drive yet still prone to heat-soak-related valvetronic faults in the taller F26 engine bay. Both generations suffer from turbo wastegate bush wear that triggers 30FF over-boost codes on UK motorways. Production ended in 2020 when the G02 X4 30i replaced it.
BMW X4 xDrive28i Models & Engines Codes
Every xDrive28i engine variant built on the F26 chassis and the specific issues each unit faces.
- N20B20A: 2.0-litre twin-scroll turbo (245 PS) used 2014-2016; timing-chain tensioner 11318608935 prone to stretch after 60k miles due to X4’s inclined oil pick-up.
- B48B20A: 2.0-litre twin-scroll turbo (252 PS) used 2017-2020; revised chain but valvetronic servo motor 11377504713 vulnerable to F26 engine-bay heat soak.
- Both codes share the 8-speed ZF 8HP45 and xDrive transfer case unique to F26, calibrated for rear-biased torque split.
- Chassis codes: F26 xDrive28i only - no RWD option - produced 2014-2020.
No other four-cylinder petrol was offered in the F26 X4; the xDrive28i sits between the diesel xDrive20d and six-cylinder xDrive35i.
Buy Used and Second-Hand BMW X4 xDrive28i Engines
Choose used for low-cost replacement, reconditioned for chains and guides already upgraded, rebuilt for full strip-down with new pistons & rings, or remanufactured to BMW factory standards with updated B48 chain drive. For the F26 xDrive28i we recommend reconditioned units because they already incorporate the revised tensioner and turbo wastegate bushing fixes.
- Used: 30-60k mile donors, compression & leak-down tested.
- Reconditioned: N20/B48 chains, guides, HPFP seals replaced.
- Rebuilt: Cracked pistons, scored crankshafts machined or swapped.
- Remanufactured: Zero-hour standard, updated BMW fasteners & gaskets.
Every grade is pressure-tested and comes with a verified F26 ECU remap to restore original 245/252 PS output.
