You're right the SMG won't allow a downshift under most circumstances. However I've seen an E60 M5 over-rev from downshifting into an incorrect gear.Who can tell me if an E60 M5 with SMG3 transmission can or cannot be over-reved? I know that there is a rev-limiter on accelleration
and that when requesting a downshift with the revs close to the redline, the SMG will not allow the downshift and the gear number will
flash to prevent the over-rev. Is this correct?????
Does anybody have any knowledge about the FAstfa secret code that is stored in the ECU of the M5? These files can only be read by BMW and not the dealer.
Any Help would be fantastic.

I'm assuming your trying to purchase an M5 and want to make sure it hasn't been over-reved? If the car is CPO'd, that means it has a warranty so could not be over-rev'd.
Are you not purchasing a CPO? This isn't a buy from a dealer?
