What crap! What do I need to say EXACTLY for them to do the upgrade?? I know this has been discussed here before, but he is going to call me this afternoon with a nay or yeah, so if someone can help me out and tell me exactly what to say, that would be great!
Couple of options:
1) go to a dealer that would do it without much fuss.
Mine was done at Tischer BMW in silver spring (route 29). They just did it no much questions asked.
2) give your SA a SIB as reference. Search here for a sib and give it to the SA. My service ticket said: software upgraded per SIB 36 06 06
There are other SIBs for this same issue.
