The gearbox update has improved the changes and the consumption.
I read in a magazine (not from the manual yet) that at high speeds the 4 wheel drive is disengaged,so is the xdrive.
The other day i made a cold start and the car was making a weird noise (br,br,br) and was shaking.The check engine came on .At workshop i was told that the thermostate is broken and was sending the wrong information (and other technical jargon i cant explain in english) to the cpu and will be replaced.So disappointed with BMW.After replacing the engine due to a broken spring in the engine,now the thermostate makes me considere to sell the car.
