I have a 2001 Astra SRI 2.2 16v Hatchback. The problem i have MAINLY happens in the morning when my car is cold. when i turn the engine on and all the lights come on for there system check and then go out, the T/C and ABS lights stay on. BUT..... strait away, when i turn my engine off, and then on again, this time they all go out!! they always, without fail go out the 2nd time i try. Anyone got any suggestions? it was put on the tester at vauxhalls and it found nothing. Only mod i have is larger diesel air intake with K&N filter. and i had a problem with the power sounder (what ever that is, i didnt see it) but that was replaced. my model does not have a T/C switch.
Many thanks guys!
