I almost think this could have been a DEF tank level sensor issue. Normally you get more than 199 miles before no start. Most get 900 plus miles when the warning comes on to give you some time to deal with needing to get it refilled.

If the sensor was faulty, it would make sense it was not giving you a warning until 199 miles. Roughly 11,000 or so miles will pass before a refill is needed for our X5, as an FYI.
