Why Choose Engine Finders for Your BMW X4 M Engine?
Engine Finders connects UK drivers with vetted specialists for reliable, reconditioned BMW X4 M replacement engines.

Whether you’re dealing with VANOS calibration concerns or turbocharger reliability, Engine Finders ensures you get the right X4 M engine fast and hassle-free.
-
✔ X4 M-Specific Timing Chain Solutions
The S58B30T0 in the X4 M (F98, 2019-2023) suffers from timing chain tensioner failures, particularly OEM 11318685179. We install reinforced aftermarket kits to eliminate the premature chain stretch documented in BMW Service Bulletin SWE-20-03.
-
✔ Direct Injection Injector Fixes
Unlike the X3 M, the X4 M’s S58 injectors (OEM 13538625379) frequently cause uneven combustion patterns. Our replacement engines include updated injectors with recalibrated spray patterns to restore factory performance and fuel efficiency.
-
✔ VANOS Calibration Updates
The X4 M’s S58 VANOS solenoids are prone to sluggish response under high loads. Our reconditioned engines incorporate the revised solenoids from BMW’s 2021 update, improving oil flow and variable cam timing precision.
-
✔ Turbocharger Durability Solutions
The twin-turbo system (OEM 11657851141/42) in the X4 M is notorious for wastegate rattle after 40k miles. Our rebuilt units are fitted with uprated bushings and ceramic-coated housings to extend turbo life well beyond OEM expectations.
-
✔ Cooling System Reinforcements
For the F98 chassis, BMW’s S58 auxiliary radiator (OEM 17118631745) often struggles during track use. Our replacement engines include upgraded radiators with higher flow rates to prevent overheating under extreme conditions.
-
✔ Crank Hub Fixes
The S58 crank hub (OEM 11238648793) in the X4 M can slip under aggressive tuning, leading to catastrophic timing misalignment. We install pinned hub solutions to permanently resolve this issue - a fix not offered by standard suppliers.
-
✔ Oil Consumption Control
The X4 M suffers from oil blow-by through valve stem seals (OEM 11347585427). Our remanufactured engines use upgraded seals with reinforced Viton material, reducing oil consumption issues noted on owner forums and extending engine longevity.
-
✔ MoT-Compliant UK Builds
All X4 M engines are rebuilt to meet UK MoT compliance, with emissions-critical parts like the catalytic converters (OEM 18308631713) upgraded to the latest EU6 standards for seamless registration and legal road use.
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 M Replacement Engines
The X4 M, first introduced in 2019 under the G02 chassis, exclusively features the high-performance S58 engine. Across production from 2019 to present, the model has seen continuous refinement, with Competition variants tuned for higher output. Common failures include crank hub slippage, turbocharger wastegate rattle, and high-pressure fuel pump issues, especially noted in early production years. BMW Service Bulletin SI B11 06 20 highlights crank hub concerns on the S58, particularly for the 2020-2021 models. Owners of the X4 M (G02) benefit from reinforced cooling and transmission systems, yet unique issues such as intercooler leaks and VANOS solenoid failures have been reported, requiring precise diagnosis. These issues are distinct to the X4 M due to its higher boost calibration compared with standard X4 petrol variants, making engine replacement or rebuilds model-specific.
BMW X4 M Models & Engines Codes
The X4 M is powered exclusively by the S58 series engines, tuned specifically for this high-performance SUV coupe. Each variant carries unique calibrations and potential weak points.
- S58B30T0 (2019-2021, G02 X4 M): 3.0L twin-turbocharged inline-6, known for crank hub vulnerability (OEM part 11317846384) and turbo heat stress.
- S58B30T0 Competition (2019-2021, G02 X4 M Competition): Increased boost pressure led to intercooler leaks and fuel injector failures under high load.
- S58B30T0 (2022-present, LCI X4 M): Revised software and cooling improvements reduced crank hub slips but issues with VANOS solenoids remain.
- S58B30T0 Competition (2022-present, LCI X4 M Competition): Tuned for 510hp with reinforced pistons; however, high-pressure fuel pump wear is common.
While the S58 is shared with the M3/M4, in the X4 M it operates under heavier drivetrain stress due to xDrive and SUV weight, creating unique wear patterns not observed in sedan applications.
Buy Used and Second-Hand BMW X4 M Engines
For X4 M owners, engine replacement options vary from used to fully remanufactured units. Each type offers distinct benefits depending on driving needs and budget.
- Used Engines: Budget-friendly but may still carry crank hub or turbo wear.
- Reconditioned Engines: Components like VANOS solenoids and fuel injectors replaced for reliability.
- Rebuilt Engines: OEM upgrades fitted, ideal for Competition variants with higher boost.
- Remanufactured Engines: Comprehensive rebuilds addressing S58-specific weak points like crank hub and HPFP.
For the X4 M, remanufactured S58 units are often recommended to ensure long-term performance under demanding xDrive loads.
