BMW 7 Series 735iL Engines for Sale | Engine Finders
Engine Finders connects UK drivers with vetted specialists for reliable BMW 7 Series 735iL replacement engines. Whether you're facing B58B30 HPFP collapse in your G11 or N55B30 VANOS failure in your F01, we deliver model-specific solutions with 12-month warranty and nationwide delivery.
BMW 7 Series 735iL Replacement Engines
The 735iL was offered across two distinct generations: F01/F02 (2012-2015) with the N55B30 3.0L turbo petrol, and G11/G12 (2016-2022) with the B58B30 3.0L turbo petrol. The F01 chassis suffers from VANOS solenoid degradation due to extended oil galleries, while the G11 experiences premature HPFP failure from UK stop-start driving. BMW Service Bulletin 12-05-18 specifically addresses B58 reliability in long-wheelbase models like the 735iL, confirming higher thermal stress on fuel systems compared to 3/5 Series variants.
BMW 7 Series 735iL Models - Engines Codes
Engine codes for the 735iL are generation-specific and tuned for long-wheelbase refinement:
- N55B30: 3.0L turbo petrol (306hp) in 735iL F01/F02 (2012-2015) - prone to VANOS solenoid failure and turbo oil seal leaks due to F01 heat soak.
- B58B30: 3.0L turbo petrol (340hp) in 735iL G11/G12 (2016-2022) - susceptible to HPFP cam follower wear by 90k miles under urban driving conditions.
- N55B30TU: Updated N55 variant (late 2014-2015 F01) with revised oil pump - still requires VANOS upgrades per BMW TSB 11-04-12.
- B58B30O0: Early B58 (2016-2018 G11) with single-scroll turbo - higher oil consumption vs later B58B30M0 variants.
Unlike the 335i or 535i, the 735iL uses unique ECU maps prioritizing smoothness over peak power, resulting in different wear patterns on fuel and valvetrain components.
