BMW MSS / MSD / MSV (Siemens)
Siemens MSS54HP
The Siemens MSS54HP is an ECU of the BMW MSS / MSD / MSV (Siemens) family. One vendor announcement cover it; they are dated and sourced below, and do not state the access route.
MSS, MSD and MSV are BMW designations for petrol control units built by Siemens, fitted to models of the 2000s — the MSS54 of the E46 M3 being the best known. These are units from before today's locks: the challenge is less about access than about calibration quality.
