BMW 3 Series 330e Engine Replacement Compare Prices & Get Quotes

A replacement engine for a BMW 330e costs £1,200-£6,500 depending on condition and generation. Used B48 engines start from £1,200, reconditioned units range from £2,500-£5,000, and fully rebuilt engines with warranty cost £3,500-£6,500. Fitting adds £800-£1,500 due to the hybrid system complexity.

• Used engines are the cheapest but come with limited warranty
• Reconditioned engines are stripped and have worn parts replaced
• Rebuilt engines are fully machined and assembled to factory specification with a 12-month warranty

Common symptoms include coolant loss without visible leaks, oil filter housing leaks (oil or coolant on the driveway), VANOS-related hesitation on acceleration, cold-start rattle (timing chain tensioner), and drivetrain fault codes (often caused by a weak 12V battery).

• Coolant leaks from the water pump or thermostat are most common
• Oil filter housing cracks cause oil/coolant mixing
• Drivetrain warnings often clear with a new 12V battery

That depends on the generation and condition of the car. A typical 330e is worth £18,000-£45,000 depending on age and mileage. A rebuilt engine at £3,500-£6,500 is well within the vehicle's value for modern G20 examples. For older F30 examples (2016-2019), assess the car's overall condition and battery health before committing.

• Modern G20 330es have strong retained value - replacement is often justified
• F30 330es with high mileage may be borderline
• Always compare quotes before making a decision

A typical engine replacement takes 3-5 days for a specialist due to the hybrid system complexity - including removal of the old unit, HV system isolation, fitting the replacement, and testing. Some suppliers offer delivery on used engines, but fitting always requires workshop time.

• Supply-only: 1-3 days for delivery
• Supply & fit: 3-5 days at the workshop
• Hybrid system requires specialist equipment and training

The B48B20M0 (2016-2019) produces 252 hp combined and was fitted to the F30 330e. The B48B20M1 (2019-2020) introduced XtraBoost, taking total output to 292 hp. The B48B20O1 (2020-present) maintains 292 hp but features revised engine management and a larger 12kWh battery for improved electric range.

• M0: 252 hp, F30 generation
• M1: 292 hp with XtraBoost, early G20
• O1: 292 hp with larger battery, G20 LCI
