I know that getting it to start again is of utmost importance, but be careful what you wish for from the dealer. I'm not sure if it applies to all HARDWARE revisions of the ECUs, but BMW has changed their code and cryptography and after a certain revision you can no longer crack ECUs with flash tunes.
The TL;DR is that you might get it back from the dealer running, and now be unable to install MHD, BM3, xHP or any flash-based tunes of any kind without doing a bench flash (remove the ECU and send it to be cracked).
