It's free8 -12 hours for ANYONE to update firmware on an ODBII connection is simply unreasonable. Every time I've ever updated BMW firmware via ODBII...even a FULL MS43 firmware re-code on my old E46 didn't take more than a couple minutes, and that's the ENTIRE Bosch engine computer being updated!!!
Yes, the ODBII serial protocol isn't the fastest, but we aren't talking gigabytes of data either!
The dealership is trying to take you for a ride you don't want to get on...
