Original engine and chassis applications
Search ECU services by part number, engine and chassis.
Use this as an identification guide for the applications below. Market, build date, gearbox and ECU version still need to match; engine conversions must be checked against the installed hardware.
- M54B25: E46, E83, E85. Selected North American/build-specific applications; check the ECU label.
- M54B30: E46, E60, E83, E85. Selected North American/build-specific applications, including E83 3.0i automatic.
- M56: E46. North American SULEV engine; confirm exact MS45.1 hardware.
MS45.1 is a separate variant. A chassis match does not establish which market specification or software is installed.
Find the ECU and read its label before ordering.
