✔ N55 Timing Chain Solutions for X4 xDrive35i
We replace the N55B30 timing chain tensioner (OEM 11317583213) prone to wear in the 2014-2018 X4 xDrive35i with upgraded designs that eliminate the specific rattle issue reported under BMW Service Bulletin SWE-14-07.
-
✔ Turbocharger Oil Seal Expertise
The N55 turbo often develops oil leaks in the X4 xDrive35i due to its unique cooling layout. Our reconditioned units include reinforced seals and bearings designed specifically for this model’s heat cycle issues.
-
✔ VANOS Solenoid Reliability Fix
Unlike other BMW models, the X4 xDrive35i (F26) experiences VANOS solenoid sticking under city driving conditions. Our reconditioned engines use updated solenoids and filters to maintain consistent valve timing.
-
✔ Direct Fitment for F26 Chassis
All X4 xDrive35i replacement engines are bench-tested and matched to the F26 chassis ECU calibration, ensuring a seamless swap without the misfire issues that arise from generic N55 units used in other BMW models.
-
✔ High-Pressure Fuel Pump (HPFP) Upgrade
The X4 xDrive35i’s N55 HPFP frequently fails after 60k miles. Our replacements feature upgraded Bosch pumps designed to handle the model’s specific fueling demands, reducing stalling and hard-start issues.
-
✔ Cooling System Reinforcement
The auxiliary water pump in the X4 xDrive35i has higher failure rates than in the 335i due to tighter engine bay packaging. Our reconditioned engines include upgraded cooling components to prevent overheating.
-

Need a reliable BMW X4 xDrive35i replacement engine? Common reasons include turbocharger wear in the N55B30 and VANOS unit failures.
BMW X4 xDrive35i Replacement Engines
The X4 xDrive35i, produced from 2014 to 2018 on the F26 platform, used the N55B30 straight-six petrol engine. This generation faced common issues such as turbo wastegate rattle, high-pressure fuel pump (HPFP) failures, and oil leakage around the valve cover gasket. BMW Service Bulletin SI B11 03 15 addressed crankcase ventilation problems affecting the N55 engine in the X4 xDrive35i. Owners of later production years also reported VANOS solenoid malfunctions, leading to poor cold starts and check engine lights. Unlike the smaller xDrive28i, the 35i’s higher boost levels stressed its cooling system, often requiring water pump replacement around 60k miles. The F26 chassis-specific calibration also introduced unique injector wear patterns not seen in other N55-equipped BMWs. For anyone replacing this engine, knowing its F26-specific technical nuances is essential for long-term reliability.
BMW X4 xDrive35i Models & Engines Codes
The X4 xDrive35i was exclusively powered by BMW’s 3.0L N55 inline-six petrol engine, tuned for the F26 chassis with xDrive all-wheel drive. Below are the specific engine codes and issues unique to this model:
- N55B30O0: 3.0L turbocharged inline-six, F26-specific calibration. Known for turbo wastegate rattle and HPFP failures.
- N55B30T0: Higher output version in select X4 xDrive35i trims, prone to VANOS solenoid failures and injector wear (OEM 13537585261).
- Technical distinction: Unlike the 335i, the X4 xDrive35i N55 engines used different cooling layouts, leading to premature electric water pump failures.
Each code represents factory-installed units specific to the X4 xDrive35i, with calibration tuned for SUV dynamics and xDrive load profiles.
Buy Used and Second-Hand BMW X4 xDrive35i Engines
When choosing a replacement engine for the X4 xDrive35i, owners can select from several options:
- Used: Cheaper, but common N55 issues like HPFP failure may still exist.
- Reconditioned: Includes replacement of VANOS solenoids and gaskets for reliability.
- Rebuilt: Addresses turbocharger wastegate and cooling failures, extending life significantly.
- Remanufactured: Fully restored with OEM-certified parts like timing chain kit.
For N55-equipped X4 xDrive35i units, remanufactured engines are highly recommended due to common turbo and cooling issues.
