Need a reliable BMW 7 Series 745Le xDrive iPerformance replacement engine? Whether you're facing hybrid system integration faults, high-voltage coolant leaks, or B48/B58 engine wear in your G11/G12 iPerformance model, we supply verified, bench-tested units with full compatibility.
The 745Le xDrive iPerformance (G11/G12, 2017-2022) was BMW’s flagship plug-in hybrid sedan, pairing a turbocharged 2.0L or 3.0L inline engine with an electric motor. Early models (2017-2019) used the B48A20O/B58B30M with known high-voltage coolant pump failures and hybrid starter generator (HSG) wear. BMW Service Bulletin SIB 12 03 19 addressed premature HSG bearing wear in G11/G12 iPerformance variants. Unlike non-hybrid 7 Series, the 745Le’s engine bay integration demands precise alignment of the electric A/C compressor and coolant lines - common failure points during improper replacements.
Engine codes for the 745Le xDrive iPerformance are specific to its G11/G12 chassis and hybrid architecture:
These engines are exclusive to the G11/G12 745Le xDrive iPerformance and differ from standard 740i/750i units due to hybrid mounting points, coolant routing, and ECU calibration.
We offer four engine types tailored to the 745Le xDrive iPerformance’s hybrid complexity:
For the 745Le xDrive iPerformance, remanufactured or rebuilt engines are strongly recommended due to the precision required for hybrid component integration.
Our reconditioned 745Le xDrive iPerformance engines include critical updates to address known G11/G12 failure points:
Every unit undergoes 48-hour bench testing simulating EV-mode transitions, coolant pressure cycles, and CAN-bus communication with the hybrid control module.
All rebuilt and reconditioned 745Le xDrive iPerformance engines include a 12-month parts-and-labour warranty.
Engine Finders is a price comparison service. Warranty terms are set by our certified UK suppliers and verified before listing.
When your engine fails, BMW 7 Series 745Le xDrive iPerformance engine works can restore performance at a fraction of the cost of a brand-new engine. From diagnostics to rebuild, here's how experts ensure optimal results.
Experts disassemble the 745Le xDrive iPerformance engine completely, inspecting for hybrid-specific component wear. Critical measurements check bore geometry, crankshaft journals, and hybrid motor integration points. This process identifies all damaged components in the B58/S63 engines used in 745Le xDrive iPerformance models from 2018-2021.
Machine shops bore and hone cylinders to exact tolerances using BMW-specific tooling for 745Le xDrive iPerformance engines. The crankshaft undergoes balancing and grinding to OEM specifications. Special attention is given to hybrid mounting points and oil passages that integrate with the 745Le xDrive iPerformance's electrical systems.
For 745Le xDrive iPerformance engines, hybrid components are carefully installed and tested. The electrical integration points are verified for proper communication with the vehicle's hybrid management system. This includes testing the hybrid motor connection points and ensuring proper electrical continuity for the 745Le xDrive iPerformance's mild hybrid system.
Worn parts are replaced with OEM-spec components specific to 745Le xDrive iPerformance engines. This includes new pistons, rings, bearings, timing chains, and hybrid-specific components. Special attention is given to turbochargers and VANOS units that are critical for 745Le xDrive iPerformance performance and hybrid integration.
Skilled technicians assemble the 745Le xDrive iPerformance engine using BMW's torque specifications and assembly procedures. Special tools ensure proper crankshaft bearing installation and cylinder head torque sequences. The hybrid integration components are carefully positioned to ensure proper electrical connections for the 745Le xDrive iPerformance's system.
The completed 745Le xDrive iPerformance engine undergoes 2+ hours of bench testing simulating hybrid operation. This includes testing electrical connections, oil pressure, coolant flow, and hybrid system communication. The engine must pass all tests before being approved for 745Le xDrive iPerformance installation with full warranty coverage.
