Just mapped out my wife's commute and it's still only 4.7 miles. Not sure if the E70 has the same issue or not (didn't see any warning about frequent trips less than 10 miles), but decided to hook up the CTEK to hers too just in case.
2012 E70 X5d (IT'S HERE!) Deep Sea Blue / Sand Beige, Premium, 3rd Row, Multi-Contour
2011 E93 335i Deep Sea Blue / Oyster, Step, Premium, Convenience (PDC & CA), and that's it
