09 135i iDrive Auto
Hello All,

I just picked a 2009 Automatic 135i w/ iDrive up from the auction. Runs and drives, but transmission is in "limp mode". I am getting an Error code of 2FA4 - DME Incorrect Data Record. I think the car may have been a repo, because the trunk was full of parts and personal stuff from the previous owner. I have heard that the working hours need to be reset in order to correct this code issue. Does anyone know how to do that in ISTA? I just got my cable from BimmerGeeks and this is my first time working with something like this. Thanks in advance.
