BMW X1 M35i xDrive (U11) Engines for Sale | Engine Finders

Whether you're replacing a failed B48B20O engine due to high-pressure fuel pump wear or addressing turbocharger lag in your X1 M35i xDrive (U11), Engine Finders sources verified replacement engines built specifically for this high-performance SUV. We focus exclusively on the U11 chassis to ensure compatibility and performance.

BMW X1 M35i xDrive (U11) Replacement Engines

The BMW X1 M35i xDrive (U11) launched in 2022 as the performance flagship of the third-generation X1 lineup, powered exclusively by the 2.0L turbocharged B48B20O petrol engine producing 306 hp. Unlike earlier X1 M35i models (F48 chassis), the U11 features revised VANOS calibration and a higher-boost turbocharger (OEM 11658637835), which -while improving throttle response -has led to increased reports of wastegate rattle and high-pressure fuel pump (HPFP) failures after 40,000 miles. BMW Service Bulletin SIB 11 03 23 specifically addresses HPFP wear in U11 M35i engines built between March 2022 and November 2023. The U11’s all-wheel-drive system and stiffer engine mounts also contribute to unique vibration-induced wear on the timing chain tensioner (OEM 11318639347), a failure point not commonly seen in non-M35i U11 variants.

BMW X1 M35i xDrive (U11) Models - Engines Codes

The X1 M35i xDrive (U11) uses a single, performance-tuned engine code across all markets, but with model-specific calibration and hardware:

  • B48B20O: 2.0L turbocharged inline-4 petrol engine (306 hp, 450 Nm), exclusive to the U11 M35i xDrive from 2022 -present. Known for HPFP (OEM 13518632941) wear and turbocharger wastegate rattle due to aggressive boost mapping.
  • B48TU2: Technical designation for the updated B48 variant in U11; features revised oil jets and a strengthened crankshaft compared to non-M35i B48 engines.
  • MHEV B48: Mild-hybrid version (48V system) introduced in late 2023 U11 models; includes an integrated starter-generator (ISG) that adds complexity to engine swaps.
  • U11-Specific Calibration ID: 0783921: Unique ECU map that increases turbo boost pressure by 0.3 bar over standard X1 xDrive28i, contributing to higher thermal stress on exhaust manifolds.

While the B48 platform is shared across BMW’s lineup, the X1 M35i xDrive (U11) uses a bespoke turbocharger (Garrett G-TF035 with BMW-specific actuator), different intercooler piping, and reinforced engine mounts that prevent direct interchangeability with non-M35i U11 or F48 engines.

Buy Used and Second-Hand BMW X1 M35i xDrive (U11) Engines

For the X1 M35i xDrive (U11), we offer three engine types tailored to its high-stress B48B20O configuration:

  • Used: Low-mileage units (<30k miles) with verified HPFP and turbo health via BMW ISTA diagnostics.
  • Reconditioned: Includes replacement of HPFP, turbo actuator, and timing chain tensioner -critical for U11 M35i reliability.
  • Remanufactured: Fully rebuilt to BMW M-spec tolerances with upgraded oil pump gears and reinforced VANOS solenoids.

Given the U11 M35i’s unique failure profile, we strongly advise against standard B48 engines; only units specifically coded and tested for the M35i xDrive (U11) ensure drivability and longevity.

  • Timing chain tensioner (OEM 11318639347) with updated nylon guide rails
  • M35i-specific engine mounts (OEM 11128638291) to reduce drivetrain shudder

Every engine undergoes a 48-hour dynamometer test simulating U11-specific load cycles, including repeated 0 -60 mph launches and sustained 120 mph runs, to validate HPFP and turbo performance before dispatch.

Warranty for Replacement BMW X1 M35i xDrive (U11) Engines

All reconditioned and remanufactured X1 M35i xDrive (U11) engines include a 12-month unlimited-mileage warranty covering core components.

  • Covers B48B20O-specific failures: HPFP, turbo actuator, timing chain system
  • Excludes damage from improper installation or modified ECU maps
  • N47/B47 diesel engines are not applicable -this warranty applies solely to U11 M35i petrol units
