BMW 640d Engine Variants We Offer and Work With

Our 30 years of experience allow us to deal with reconditioning and fitting the full range of BMW 640d diesel engine variants used across the 6 Series lineup. During those years, we have noticed that the N57D30B 3.0 L twin turbo diesel engines fitted to the F12 Convertible, F13 Coupe and F06 Gran Coupe models are the most popular among BMW drivers. We have complete units available as low mileage used engines, fully reconditioned replacements and rebuild ready cores across all generations of the BMW 640d.

You can choose from our extensive stock of earlier, closely related M57 diesel variants used in previous BMW diesel platforms. We ensure that every engine is matched by the engine code, generation and vehicle specification to ensure correct compatibility across drivetrain layouts and production years.

Quality BMW N57D30B engine for sale

The standard 640d engine code is N57D30B, and BMW also refers to this unit as the M57D30 (306D5) in earlier 6 Series models. The F12 convertible, F13 coupe and F06 Gran Coupe share the same engine code and similar power output. When buying a replacement engine, it is essential to select the right code and capacity. Our stock includes complete engine N57D30B units and N57D30B engines for the BMW 6 Series F12 and F13. We also carry other 6 Series engines – such as the N52B30A, N62B44A and N63B44A – for customers with petrol models. Each engine is checked for oil pressure, compression and timing chain condition before sale, and we record the vehicle identification number so that you can match the right engine for your BMW.

How Do We Source Our BMW 640d Engines & Maintain Quality?

An engine replacement is not worth its salt if it does not provide the performance and reliability that the owner of the vehicle craves. This is the reason we have developed a strict quality approval process to meet the high standard we set. It starts with us selecting the donor vehicles from verified sources and making sure the cars are accompanied with full service history. Mileage verification is done from its ECU, and BMW diagnostic scanning is done to identify fault codes, sensor irregularities and control unit data.

Our mechanics confirm the mechanical integrity through compression and leak down testing, along with visual and physical inspection of critical components such as the turbocharger, cooling system, and timing chain. Units that fail to meet our standards are rejected outright. We uphold our standards and approve fewer engines to ensure long term reliability and performance.

Transparent BMW 640d Engine Pricing, UK Delivery & Professional Fitting Support

The price of the replacement engine is one of the most important aspects of the whole process, and every driver is wary of paying more than he should. This is the reason we strictly maintain transparent prices for our engines. Used BMW 640d engines typically range from approximately £2,000 to £3,200, while fully reconditioned BMW 640d engines go between £3,800 and £6,500+.

However, the final price depends upon mileage, overall engine condition, warranty duration, and whether the engine is supplied only or professionally fitted. We offer all the engines with fast nationwide delivery across the UK, or you can opt for our in house precision installation, calibration and performance validation. You can simply book an appointment by filling out the simple form, and our dedicated team of representatives will take care of it.
