BMW 6 Series 640d Gran Coupé Engines for Sale | Engine Finders
Whether you're facing premature N57D30 engine failure due to timing chain wear or EGR cooler leaks specific to the 640d Gran Coupé, Engine Finders supplies verified replacement engines with UK stock, 12-month warranty, and direct fitment for F06/F12/F13 chassis.
BMW 6 Series 640d Gran Coupé Replacement Engines
The 640d Gran Coupé (F06/F12/F13, 2012-2018) exclusively used the 3.0L N57D30 diesel engine, renowned for strong torque but prone to timing chain tensioner failure (OEM 11317589894), high-pressure fuel pump (HPFP) wear, and EGR cooler carbon buildup. BMW Service Bulletin SIB 11 03 13 specifically addresses premature timing chain stretch in N57 engines used in Gran Coupé applications due to sustained high-load driving profiles. Unlike the 540d, the 640d Gran Coupé’s engine mapping and exhaust routing accelerate EGR valve coking, making full-system replacement critical during engine swaps.
BMW 6 Series 640d Gran Coupé Models - Engines Codes
All 640d Gran Coupé variants used the N57 engine family, but with Gran Coupé-specific calibration and ancillary layouts. Key engine codes include:
- N57D30A: Early 640d Gran Coupé (2012-2014, F06/F12/F13) -313 PS; susceptible to timing chain guide wear (OEM 11317589894)
- N57D30B: Mid-cycle update (2014-2016) -revised turbo and EGR; improved but still prone to HPFP (Bosch 0445020095) failure
- N57D30C: Final production (2016-2018) -enhanced oil pump; reduced but not eliminated timing chain issues
- All variants feature Gran Coupé-specific engine mounts (OEM 11127585991) and exhaust manifolds incompatible with standard 640d saloon units
While the N57 appears in 5 Series and 7 Series models, the 640d Gran Coupé uses a unique engine harness, turbocharger orientation, and oil pan design requiring exact-match replacements.
