OK, I did as someone in this group suggested and had the software upgraded in my 550i 2006. They did find several "software faults" and upgraded it. But I still have both problems:
1) Comfort Access: works sometimes, sometimes doesn't (have to hold the key up to the window to get it to work) 2) iDRIVE: Sometimes starts right up, sometimes sits on the BMW screen for up to 15 seconds.Anyone else find the solution to these problems?
Thank you Niels. I will try. I did take it in already onece for the comfort access. They said it was a "software issue" and upgraded to the latest software. However, the problem still occurs. I will ask them to change out the battery and check the antenna. unfortunately, here in San Antonio Tx we have only one BMW dealer and their service department is terrible.
