That IS annoying, X5!
Two benefits could come of this tho:
1) You make clear to the dealer that due to the inconvience of the unnecessary drive, you expect a wash & detail while you sip coffee in the lounge. Even my wife enjoyed the roses they gave last time

2) Then again, 60 miles is a loong way to go for a wash, so perhaps it's time to pick up a code-reset tool? This error would be covered on obc2, cause it relates to engine/trans, right? It's not one of the Bimmer-specific ones that requires a sep reader, is it?
