BMW MSS / MSD / MSV (Siemens)
Siemens MSS54
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.
