When I recieved the car back from the dealer the following modules had been updated,
DME/DDE 7619981 -> 8618483
JBBF 9247477 -> 9305740
DSC 6789304 -> 6862873
CAS 9227053 -> 9287534
KOMBI 9221631 -> 9242396
MOSTGW 9245878 -> 9302172
MASK/CCC 9242510 -> 9302177
FAS 9221861 -> 9264974
BFS 9221861 -> 9264974
FRM 9240529 -> 9308367
KLIMA 9242407 -> 9292259
I reflashed the car with the Alpina software and was delighted to find the tach problems no longer exsist.

Guess this answers my question as to whether the dealer will notice/care about the flash. Just out of curiosity, did you update your UIF when you did the flash? Does your WinKFP show the flash history (with dates and dealer number) when you read the AIF with it?

Any guide on how to do this with Winkfp? Im guessing its almost identical to the method for the TCU flash but are there any precautions I should take?
Any data I should backup (coding, VO, etc... I am new to BMWs so I dont want to screw myself)
I know this is an old thread but I am on a quest
