[Garage called DAD]

Hello All,
Sorry to trouble you.
Found out what BMW stands for Bl??DY MOTOR WINs. (Arrgh)
Quick summary
FRM3 died after battery disconnected. Had it reflashed. :-) All OK
Warned my son he needs a new battery.
FRM3 Died. Turns out the battery died. Who saw that coming?? Re flashed :-) All ok
Phone call cars not right. FRM3 died again. Sent it off to be reflashed again. But also bought another frm exact match apart from s/n and mfg date. reflashed module turned up. Son fitted it.Seen on the car now but indicators windows etc not working. Disconnected battery to make to remove FRM to make sure no pins bent. AAARRRRGGGHHH FRM died again. Replacement turned up. All working. Looking at the error codes the replacement came off an M3 going into a 316d. So I now have to Program the VIN and VO into the replacement FRM3. I have read so much Im totally confused. Any one have a step by step procedure to do this?
Car is a 2010 E90 316d saloon.
Software available. Inpa, WinKP, NCSexpert, NCSdummy,Tool32
Cable K-Dcan
So I dont have to wait for someone to repflash an FRM have ordered an X-prog and a UPD-USB programmers. (That will be my next question If I cant work it out.)

Any suggestions much appreciated.
