Postal EWS delete services for the BMW Z4 E85 roadster with M54B22, M54B25 or M54B30 engines and confirmed Siemens MS45 hardware. Identify MS45.0 or MS45.1 from the complete ECU label before ordering.

These services are carried out on your ECU. Search by ECU part number, engine and chassis, or find your ECU and read its label. The S54-powered Z4 M uses different management and requires a separate check.
