BMW X5 sDrive 35i Replacement Engines
Produced from 2013 to 2018 on the F15 chassis, the X5 sDrive 35i was fitted with the N55B30A 3.0L turbocharged petrol engine. Owners often reported timing chain wear, high-pressure fuel pump issues, and VANOS solenoid malfunctions, highlighted in BMW Service Bulletin SI B11 03 13. Unlike xDrive variants, the sDrive 35i featured different drivetrain calibration that led to unique oil consumption patterns under heavy load. Later service updates improved valve cover gasket reliability, but turbo wastegate rattle remains a recurring issue for 2013-2016 units.
BMW X5 sDrive 35i Models & Engines Codes
The X5 sDrive 35i primarily uses one key engine code across its production years. Below is the breakdown:
- N55B30A: 3.0L inline-6 turbocharged petrol, fitted exclusively in the F15 X5 sDrive 35i (2013-2018). Known for timing chain tensioner wear (OEM 11317583220), turbocharger wastegate issues, and occasional injector failures.
- Performance: 302 hp with smooth torque delivery, paired with an 8-speed automatic. In the sDrive variant, shorter gear ratios created distinct wear on timing chain guides compared to the xDrive version.
While the N55 engine was shared across other BMWs, in the X5 sDrive 35i it ran a unique cooling setup that increased water pump stress and shortened its service life.
Buy Used and Second-Hand BMW X5 sDrive 35i Engines
Replacement choices for the X5 sDrive 35i include used, reconditioned, rebuilt, and remanufactured N55B30A units. Each option offers different value points.
- Used: Taken directly from donor vehicles, with no internal rework.
- Reconditioned: Fitted with new gaskets, seals, and common failure part replacements like VANOS solenoids.
- Rebuilt: Complete disassembly, machining, and replacement of key components including timing chain kits.
- Remanufactured: Factory-level rebuild with OEM parts, ideal for high-mileage N55 engines prone to turbo and fuel system faults.
For N55-equipped sDrive 35i units, remanufactured engines are often recommended due to their reinforcement of known weak points.
