Take a look at the ThinkDiag instead of the Foxwell. I have both and for the money the ThinkDiag is a better option
If you are going to spend that level of cash on an app based version then Bimmergeeks Protool is arguanly the best.
Unlike ThinkDiag they only eat and and breathe bimmers and have a deep and long history of support..FWIW
