Need a little coding help e46
So I have 2004 M3, I wanted bluetooth a couple of years ago and my car came with a tcu that had a bt passkey but did not function; I went on ebay and purchased another tcu from I believe an 05 330. So I swapped the modules out and I've had bluetooth ever since. So everything works but one thing has always bugged me, my tcu and bt name are matched to the vin of the donor car. I have a general idea of how ncs expert works and have used it to code some things on my 11 x5 but I can't seem to figure out how to change the vin on the tcu on my m3. Any help would be greatly appreciated. As I said before everything works it's just more of a vanity issue for me, it's like a job half way done and that bugs the **** out of me.
