Why Choose Engine Finders for Your BMW X6 M50d Engine?
Engine Finders connects UK drivers with vetted specialists for reliable, reconditioned BMW X6 M50d replacement engines. From the quad-turbocharged B57D30C diesel to the later B57D30S0 variants, we provide solutions tailored to the X6 M50dās unique engineering. Whether you need a replacement due to turbocharger actuator failures or timing chain stretch issues reported on 2018-2021 G06 models, Engine Finders makes it easy to locate the correct engine quickly and with confidence.
-
ā X6 M50d Timing Chain Upgrades
The B57D30C in the X6 M50d (G06, 2018-2021) is prone to premature wear of the timing chain tensioner (OEM 11318576849). Our reconditioned engines include reinforced tensioner assemblies to eliminate stretch issues highlighted in BMW Service Bulletin SWE-19-04.
-
ā Quad-Turbocharger Reliability
Unlike other BMW diesels, the X6 M50d uses a complex quad-turbo setup on the B57D30C. Failures often occur in the low-pressure turbo actuator (OEM 11658593084). We supply fully reconditioned units with upgraded actuators designed for the X6ās high-boost demands.
-
ā EGR Cooler Replacement for M50d
The B57D30C EGR cooler (OEM 11718594847) in the X6 M50d suffers from cracking due to higher thermal loads compared to the 30d. Our replacement engines include the updated cooler, preventing coolant leaks and exhaust contamination.
-
ā Oil Pump Drive Reinforcement
On G06 X6 M50d models, the oil pump drive chain (OEM 11418585049) can wear prematurely under high load. Our rebuilds include a reinforced oil pump drive to prevent oil starvation - a failure unique to the M50dās tuned diesel configuration.
-
ā VANOS Solenoid Calibration
While the B57D30C shares VANOS technology with other diesels, in the X6 M50d (G06) the solenoids are tuned for quad-turbo response, making them more prone to clogging. Our reconditioned engines use recalibrated VANOS units to restore performance.
-
ā Fuel Injector Reliability
The high-pressure injectors (OEM 13538594975) on the B57D30C are known to leak on the X6 M50d due to increased combustion pressures. Our replacement engines include upgraded injectors specifically tested under M50d load conditions.
-
ā Chassis-Specific Calibration
Unlike the 30d, the X6 M50d (G06 chassis) uses bespoke ECU mapping that affects engine wear patterns. Our reconditioned units are calibrated specifically for the G06 platform to ensure seamless integration and long-term reliability.

BMW X6 M50d Engines for Sale | Engine Finders
Engine Finders connects UK drivers with vetted suppliers for reliable BMW X6 M50d replacement engines, covering both N57S triple-turbo and B57D30C quad-turbo diesel units known for timing chain and turbocharger failures.
BMW X6 M50d Replacement Engines
The X6 M50d launched in 2012 (E71 LCI) with the N57S 3.0L inline-six tri-turbo diesel producing 381hp. In the F16 generation (2015-2019), the same engine was refined but retained weak points in the timing chain (OEM 11318577065) and turbo oil feed seals. The G06 X6 M50d (2019-2020) introduced the B57D30C quad-turbo engine, raising output to 400hp but introducing unique EGR cooler issues (BMW Recall 0011520600) and swirl flap wear. Chassis codes include E71 LCI, F16, and G06 specific to the M50d only, each carrying unique repair needs that our network covers comprehensively.
BMW X6 M50d Models & Engines Codes
The X6 M50d uses highly specialized diesel engines across generations. Each code carries unique traits and weak points owners must be aware of:
- N57S (2012-2019, E71 LCI/F16): 3.0L tri-turbo diesel, known for timing chain wear (OEM 11318577065) and crankshaft bearing stress in M50d calibration.
- B57D30C (2019-2020, G06): 3.0L quad-turbo diesel, suffers from EGR cooler leaks (BMW Recall 0011520600) and swirl flap actuator failure.
- N57D30T0 (2015-2017, F16 transitional spec): Special tuning variant, common injector issues and turbo seal leaks under high boost.
- B57D30S0 (late G06 export markets): Limited production engine, with unique SCR AdBlue system calibration failures.
While N57 engines also appear in 740d or 535d, the M50d tuning stresses components differently, making replacement engines for this variant uniquely prepared for higher boost loads and thermal stress.
Buy Used and Second-Hand BMW X6 M50d Engines
Owners can choose from used, reconditioned, rebuilt, or remanufactured M50d engines depending on budget and long-term reliability requirements.
- Used: Budget option, typically higher mileage, risk of inherited N57 timing chain wear.
- Reconditioned: Cleaned and tested with new bearings and seals, ideal for N57S engines with early wear.
- Rebuilt: Comprehensive teardown, replacing known weak points like turbo seals and chain tensioners.
- Remanufactured: Factory-standard rebuild with OEM parts (timing chain 11318577065, EGR cooler 11717810871), recommended for G06 B57 owners.
For the M50d, remanufactured engines are strongly advised due to high stress loads from triple/quad-turbo setups.
