BMW 6 Series 640i xDrive Gran Turismo Replacement Engines
The BMW 6 Series 640i xDrive Gran Turismo (F06 LCI, 2012-2018) features the N55 twin-scroll turbocharged petrol engine, known for its high-performance output but susceptible to specific issues. The N55 in the 640i xDrive GT experiences unique stress patterns due to the xDrive all-wheel-drive system and Gran Turismo's extended body design. Common failure points include high-pressure fuel pump degradation after 80,000 miles and turbocharger wastegate actuator wear due to extended high-boost operation in the F06 platform. BMW Service Bulletin SWE-19-03 specifically addresses these issues for 640i xDrive GT models, recommending updated components during rebuilds.
BMW 6 Series 640i xDrive Gran Turismo Models - Engines Codes
The 640i xDrive Gran Turismo features the N55 twin-turbo petrol engine, specifically calibrated for the F06 chassis and xDrive system integration. Each engine code has unique failure patterns specific to the 640i xDrive GT's operating conditions.
- N55B30A: 3.0L twin-scroll turbo petrol (2012-2018 F06 LCI) - known for HPFP issues in 640i xDrive GT after 80,000 miles
- N55B30A (LCI): Updated version with modified ECU mapping for xDrive integration in 640i xDrive GT (2015-2018)

3. Cylinder head resurfaced to 0.05mm flatness; new MLS gasket installed with 25Nm + 90° torque sequence per TIS 11 12 010.
4. Turbocharger rebuilt with updated wastegate actuator - known failure point in 2012-2018 6GT models under sustained boost.
5. HPFP upgraded to Siemens unit as mandated by BMW SB B12 03 18 to prevent rail pressure drops at 6,000rpm.
6. Post-build ECU coding via ISTA to match 6GT's xDrive transfer case and rear air suspension - prevents limp mode on startup.
