Hi, thanks for your replies. i have found a previous post from a member who seemed to have the same problems. he said he had a faulty near side front sensor.
I am going to try to get the part that i need and have it fitted. I dont suppose that i could push the boat out here and ask does anyone know the exact name of the part i need?
sorry to sound stupid but i'm completely in the dark. I owuld like to know exactly what i need because i have lost faith in my local garage. i left the car in last week and nothing is fixed. since i've had the car back the sunroof has stopped working also. but i'm going to try to tackle the sensor problem first
