Recently I have had to reset the Date & Time on my e90 at least 3 times !
Not sure if it is coincidence or not - but this seems to have begun after flashing to 7.40.12 ?
I am not convinced that it is isn't a coincidence , as I haven't read about anyone else having this problem after flashing , so am keeping an open mind
Although , touch wood , has been fine for a couple of days now !
