No problems.
I just did it on my 07 X5.
I came to the service to do n early oil changhe and my computer was still showing 3,500 kms to the oil change but it was more then a year in between, so they have changed it for free but did not reset the computer, saying that BMW will not pay for a reset unless the computer is showing it, so I have asked them if I could do it myslef instead of waisting my time and coming back. They said I could if I knew what to do.
I did it... :-)
