Depending on the variant, it was offered with rear-wheel drive or xDrive all-wheel drive, paired with the eight-speed Steptronic automatic. Engine management is by a BMW DME; identify the exact ECU hardware and software from the vehicle before ordering a file.
About the BMW 540i G30/G31
The BMW 540i is the six-cylinder petrol model of the G30 Sedan and G31 Touring 5 Series, available as the 540i and 540i xDrive. Throughout this generation it uses an eight-speed Steptronic transmission.
The key difference is the LCI update. Pre-LCI cars use the B58 without a mild-hybrid system, while LCI models add a 48V mild-hybrid system with a starter-generator. After the update, the Touring was offered as the 540i xDrive. Exact ECU hardware and software should be confirmed from the vehicle before a calibration file is prepared.
Please tell us whether your car is pre-LCI or LCI, along with its production date, body, drivetrain, current software and fuel. On LCI cars, any stored faults in the 48V system should be resolved first, and modifications or previous tuning should be listed.
