About the BMW 540i xDrive G60
The BMW 540i xDrive is the six-cylinder petrol model of the G60 5 Series in North America, introduced for the 2024 model year with production starting in November 2023. It combines an inline-six with a 48-volt mild-hybrid system and xDrive all-wheel drive.
Power reaches the wheels through an 8-speed Steptronic transmission. Because the mild-hybrid system works alongside the engine, its condition matters before calibration, and the ECU hardware and software are identified from the specific vehicle before a file is prepared.
Please include the production date, the market the car was delivered to, the current software, fuel grade and any modifications. Tell us about stored 48V system faults and any earlier calibration work.
