BMW 5 Series G30 (2017–2023) — Diagnosis

The table below is the real diagnostic profile the Diagnost program uses for the BMW 5 Series G30 (G30/G31) — every unit it polls, reads fault memory from and (where marked) codes. This is not marketing: it is the program's working database.

Fault memories on this car (if it has a CAN bus — roughly 2008 and newer) are read by the program with an ordinary ELM327 adapter too. A K+DCAN cable (E series) or ENET cable (G series) in the Windows version is what unlocks dealer-level depth: coding, service intervals, factory options, per-module mileage and the full fault list for every unit in the table above.
