Hello,

I've brick an MEVD17.2.G ECU during tuning car (Bootmode). DME has permanent failure.

I've ordered from BMW Dealer a New DME, the dealer ask for VIN because ECU should be coded before shipping.

I've never replace DME on BMW F serie.

I prefer install DME without opening it... If not possible then I can open Ecu for bootmode and flash backup from old ECU (if no OTP AREA Conflict)

Who can explain me the right procedure for install the new DME? Just install it and start?

Need to program the sw with diagnostic tool (I've original AVDI or a friend with Ista)?

What Thinking for ISN? New Ecu come with the good ISN (because buy from VIN) or I need to copy ISN from old ecu to new ECU?

Thanks for any help!

Regards.
