- Reconditioned units include updated HPFP per SB B12 07 20
- Used engines must match F06 LCI chassis - 8HP70 transmission calibration
- Avoid early 2017 B58s - pre-update injectors prone to carbon coking in 6GT
BMW 6 Series 640i Gran Turismo Replacement Engine Cost in the UK
- New B58 engine: £5,800-£6,400 (dealer only, includes xDrive coding)
- Reconditioned: £3,900-£4,500 with 24-month warranty on turbo - VANOS
- Used pull-out (2019-2021): £2,600-£3,200 - verify injector service history
- Engine Finders users save avg. £920 vs main dealer on 640i Gran Turismo
Finding the Right BMW 6 Series 640i Gran Turismo Engine
- Check VIN - 640i GT uses F06 chassis (not G32 or F13)
- Engine code B58B30M0 stamped near oil filter housing on block
- Avoid 540i G30 B58 engines - different engine mounts - coolant routing
- Confirm ECU matches 6GT’s active rear axle steering - air suspension
BMW 6 Series 640i Gran Turismo Petrol vs Diesel Engines
- 640i GT only offered with B58 petrol - no diesel variant exists
- Petrol avoids ULEZ; 640d GT (if existed) would incur £12.50 daily charge
- B58’s 500Nm torque suits 6GT’s 1,920kg weight better than smaller engines
- Petrol ideal for mixed driving - diesel unavailable for this trim level

BMW 6 Series 640i Gran Turismo Engine Works: How Experts Rebuild Engines
When your engine fails, BMW 6 Series 640i Gran Turismo 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 teardown using BMW special tool 88 88 6 456 for B58 camshaft phaser alignment - essential for 6GT’s precise VANOS timing.
2. Block bored to 82.00mm with new Mahle forged pistons (OEM 11118619877) - required due to high thermal stress in Gran Turismo long-distance use.
3. Cylinder head resurfaced to 0.04mm flatness; new MLS gasket (11128619878) torqued to 22Nm + 90° + 90° per TIS 11 12 025.
4. Turbocharger rebuilt with reinforced wastegate rod (13718619879) - known weak point in 2017-2019 640i GT under repeated high-load cycles.
5. HPFP upgraded to Bosch unit as mandated by BMW Service Bulletin B12 07 20 to prevent fuel rail pressure drop at 6,000rpm.
6. Post-rebuild ECU flash via ISTA+ to sync with 6GT’s rear-wheel steering and adaptive air suspension - prevents drivetrain error codes.
