BMW i5 eDrive40 (BEV) Engines for Sale | Engine Finders
Engine Finders connects UK drivers with trusted specialists for genuine BMW i5 eDrive40 (BEV) replacement electric drive units. Whether you need a replacement due to stator winding degradation, inverter coolant leaks, or MGU thermal runaway in your G60 i5 eDrive40, we help you find the right BEV powertrain-fast and affordably.
BMW i5 eDrive40 (BEV) Replacement Engines
Launched in 2023 on the G60/G61 platform, the i5 eDrive40 is BMW’s all-electric variant featuring a single rear-mounted electric motor (code: 5EM). Unlike combustion-powered models, the i5 eDrive40’s propulsion system integrates the electric motor, single-speed transmission, and power electronics into one compact drive unit. Early G60 units (2023-2024) have shown susceptibility to high-voltage coolant pump seal failure and stator insulation breakdown under repeated fast-charging cycles. BMW Technical Service Bulletin TSB-BEV-2023-11 identifies thermal stress in the motor housing as a root cause in pre-Q2 2024 builds. Engine Finders sources only units compliant with the latest BMW ISTA/P BEV calibration standards for seamless integration.
BMW i5 eDrive40 (BEV) Models - Engines Codes
The i5 eDrive40 uses a single electric drive unit across all model years, but internal revisions affect compatibility and reliability:
- 5EM (2023-present): 250 kW (340 hp) rear-mounted electric motor in i5 eDrive40 (G60/G61). Early units (Jan-Jun 2023) prone to inverter coolant leaks due to brittle hose clamps.
- 5EM Rev. B (Jul 2023-present): Updated stator winding insulation and reinforced coolant seals per BMW SIB 61 12 23.
- 5EM with HV Pump v2 (Q2 2024+): Features upgraded electric coolant pump addressing seal degradation in high-ambient-temperature conditions.
- Integrated Transmission (Code: GETR-5EM): Single-speed reduction gear with lifetime fluid-failure typically tied to motor bearing wear, not gear wear.
All units are specific to the G60/G61 chassis and are not interchangeable with i4 or i7 drive units due to mounting geometry and HV connector placement.
Buy Used and Second-Hand BMW i5 eDrive40 (BEV) Engines
We offer four engine types tailored to BEV reliability needs:
- Used: Low-mileage pull-outs from accident-damaged G60 i5s, fully HV-discharged and inspected.
- Reconditioned: Restored 5EM units with replaced bearings, updated coolant lines, and thermal sensor recalibration.
- Rebuilt: Core units upgraded with Rev. B stator and v2 coolant pump for pre-2024 models.
- Remanufactured: Fully disassembled, dyno-tested drive units rebuilt to BMW G60 BEV factory specs.
For i5 eDrive40 owners, we strongly recommend reconditioned or rebuilt units to address known early-production weaknesses in the 5EM motor.
