BMW X6 xDrive 40d Replacement Engines
The X6 xDrive 40d has evolved through three generations with distinct engine configurations. The first generation (E71, 2009-2014) used the M57N2TOP 3.0L twin-turbo diesel, known for sequential turbocharger failures (OEM 11657845922) and high-pressure fuel pump issues. The second generation (F16, 2015-2019) introduced the N57S engine with improved efficiency but continued DPF regeneration problems specific to the X6's weight and usage patterns. The current generation (G06, 2019-present) features the B57D30 engine with updated emissions systems. BMW Service Bulletin SIB 12 09 15 addresses the common turbocharger wastegate failures in early M57N2TOP units used in the X6 xDrive 40d.
BMW X6 xDrive 40d Models & Engines Codes
The X6 xDrive 40d utilizes several engine codes across its production history, each with specific characteristics and common failure points unique to this model.
- M57N2TOP: 3.0L twin-turbo diesel (2009-2014 E71) - Known for sequential turbocharger failures and EGR cooler issues (OEM 11747845573) in X6 xDrive 40d due to high exhaust temperatures
- N57S: 3.0L single-turbo diesel (2015-2019 F16) - Improved efficiency but prone to DPF clogging and injector failures specific to the X6's heavy usage patterns
- N57D30O0: High-output version in M50d models - Features triple-turbo configuration with unique cooling requirements for X6 application
- B57D30: 3.0L diesel (2019-present G06) - Updated emissions systems but still experiences AdBlue system issues in X6 xDrive 40d applications
Unlike other BMW models using these engines, the X6 xDrive 40d versions have specific cooling system calibrations and transmission mappings to handle the SUV's weight and performance demands.

Expert Tips for Choosing the Right Engine for Your BMW X6 xDrive 40d
BMW X6 xDrive 40d Engine Types Explained
- N57D30B (E71/F16, 2009-2019) twin-turbo diesel, timing-chain risks.
- B57D30 variants (G06, 2019-on) modern straight-6, improved modular design.
- Reconditioned N57 with OEM timing kit (11317797898) recommended.
- Used low-mileage B57 units work well if service history is verified.
BMW X6 xDrive 40d Replacement Engine Cost in the UK
- N57D30B reconditioned units typically £2,500-£3,800 fitted UK.
- B57D30 reman engines (G06) usually £3,200-£4,500 fitted UK.
- Exchange/used N57 units cheaper but demand full timing service.
- Expect extra for turbo/EGR work on high-mileage X6 xDrive 40d cars.
Finding the Right BMW X6 xDrive 40d Engine
- Check VIN and engine stamp for N57D30B (E71/F16) production codes.
- G06 X6s (2019+) list B57D30 variants in the engine bay / VIF plate.
- Match transmission and engine mounts - E71 and G06 mounts differ.
- Don't swap N57 for B57 without confirming ECU and ancillaries fit.
BMW X6 xDrive 40d Petrol vs Diesel Engines
- X6 xDrive 40d is diesel: N57 (2009-2019) then B57 (2019+), diesel only.
- N57D30B shows EGR/DPF calibration issues on some 2009-2019 X6s.
- B57 brings improved emissions control but still needs quality oil.
- For heavy towing/long miles choose B57 with full service history.
Quality Assurance & Warranty
- Timing kit replacement using OEM 11317797898 / 11318490219 on N57s.
- Use full timing service kit (e.g., 11318570649CKT) on N57 rebuilds.
- Engine Finders checks EGR, turbo shaft play and injector codes on X6s.
- Ask for 12-24 month parts warranty specific to X6 xDrive 40d swaps.
Compare & Save on BMW X6 xDrive 40d Engines
- Prefer matched-mileage B57 units for G06 X6s to avoid premature wear.
- Avoid suppliers who skip N57 timing tensioner and guide replacements.
- Request photographic evidence of turbo/DPF condition before buying.
- Get multiple UK quotes - insist on fitment details for X6 xDrive 40d.
BMW X6 xDrive 40d Engine Works: How Experts Rebuild Engines
When your engine fails, X6 xDrive 40d engine works can restore performance at a fraction of the cost of a brand-new engine. From diagnostics to rebuild, here's how experts ensure optimal results.
1. Full diagnostic & strip-down
Workshop runs ISTA/DDE history check, compression and leakdown tests, then removes the engine. For N57D30B X6s technicians inspect rear timing cover and turbochargers for oil leaks. All fault codes are saved and compared to BMW TSBs before proceeding.
2. Timing system renewal
For N57 X6 xDrive 40d engines replace upper/lower chains, guides and tensioners using OEM kits (examples: 11317797898, 11318570649CKT). Technicians use the BMW timing tool set for N57/N47 to ensure correct cam/crank alignment before refit.
3. Cylinder head, injectors & turbo work
Strip head, inspect valve train and injectors; replace worn injectors or turbo cores. N57 head bolts follow staged torque procedure (example stages: 50Nm → 70Nm → 100Nm → 120Nm). Replace ancillaries like EGR cooler where corrosion or soot damage is present.
4. Bottom end inspection & bearings
Measure crank journals, check big/end and main bearings for scoring. Replace main caps / bearings as required, fit new oil pump and prime system. For high-mileage X6 xDrive 40d engines balance rotating assembly and check endfloat to OEM tolerances.
5. Reassembly with OEM parts & calibration
Reassemble using genuine BMW fasteners/parts where specified (timing kits, tensioners, turbo bolts). Fit refurbished or new turbos with matched shaft play checks. Program ECU and perform VANOS/adaptation procedures where applicable for B57 variants.
6. Final testing, emissions & warranty
Road test with live data capture, DPF regen check and smoke test. Confirm EGR and particulate sensors clear (note extended warranty campaigns have covered some N57/N47 sensors). Supply full invoice, photos and 12-24 month warranty specific to X6 xDrive 40d rebuilds.
