Took my bike in for the 1,000 km service last week. Shift Assist Pro was working fine on the way in but wouldn't work while riding home afterward. I called the dealership who said that it couldn't have been anything that they did. At that point they also told me that there is a service bulletin out for part of the unit coming loose. They couldn't do the work until they received a special tool from BMW which finally arrived today. I'll take her in tomorrow and hopefully it's a quick fix. So if you got this option, give your dealer a call to ask about getting it checked out.
