Every body style and trim level sold during the first-generation production run is fully supported.

All four engine families are covered: the N46 2.0L four-cylinder, the M54 2.2L and 3.0L inline-six, the N52 3.0L inline-six used in the facelift 3.0si, and the high-revving S54B32 3.2L inline-six (330 hp) found exclusively in Z4 M models.

What format is the manual?
This is professional OEM BMW dealer software, not a PDF. It runs on Windows (XP through 11) as well as Mac and Linux, and features interactive wiring diagrams, component locators, and searchable step-by-step procedures – identical to the platform used at authorized BMW dealerships.
