If you get it coded at this time, your BT and gongs will go quiet-- there is no official fix from BMW on it at this moment. I'd hang on for a bit and see if a few of us who are pushing back to BMW get any satisfaction.
Thanks for the help, I guess Ill just wait to hear what happens ugh was really looking forward to having it done
Please keep us updated woodchuck
