problem details
During freezing temps, my car won't start up. It has to have at least 3/4 tank of gas in it at all times
The solution was that BMW replaced the manifold, throttle body and valve to the tune of 600euro ($850) on a car that is only 4 years old! I am writing to BMW, because this is a defect!!
