Cars not lost. They just need to be recovered. Recovering the "gateway" as they call it.
F30's have 15 or so modules that need to be programmed (some other models up to 20 modules) and BMW uses the Bosch developed serial CAN BUS. Bus speed is very slow, like 1989 slow. But its reliable and does the job so its still in use by many OEM's. I think CAN BUS is the standard for OBDII.
As far as regression testing, one would think they'd have this updating process down to a science. Apparently, they don't. I'm told that this has happened before and not just once before.
