My SES light on my x5 (01 / 3.0) comes on and off. It seems that when I open the gas cap, it resets and turns off. After driving for a while goes on again.
I have not had a chance to take it to have the code read yet, (actually a couple of times when I was going to go for the reading the light was off).
Could it be this from another posting ?:

The reason for it is that it seems that when I open the gas cap it vents or something like that.
Maybe someone here has experienced the same. Thanks in advance for your help.
