They screwed me with $2k for a new DME and installation. Dealer could not diagnose the issue so a BMW field service rep was called out and he flagged the repairs since the system was tampered with. I went into the dealer with no modifications.
Did you unplug the battery when you were installing Jb4?
Of course..
