Need some help again.
The story is that my S3 had a cracked head so the garage have fitted a new one. Once they put it all back together they said it started up straight away and ran very well. But then it developed a fault and will only start 1 in 5 attempts. They have scanned the car and the fault that comes up is Cam shaft sensor below threshold. So they fitted a new sensor but this hasn't solved the fault, they then took the cam cover off and checked the timing and tensioner etc and it is all ok.
Any ideas what the problem would be?
I just want me car back now.
Thanks in advance.
