The X3 in day to day running does NOT charge the battery to 100% each time, it only charges to 80%, so lots of small runs and using a lot more electrical power will run in it down to a level where you get random errors/problems. I had similar problems with different error messages and purchased a trickle charger and charged mine overnight for several days. This works everytime. If BMW have cars in their garage for more around 3 or 4 weeks they do the same. It is common practice in the UK.

Great info. What is a "short run" Less than 12 miles or less then 4 Miles?
