To be honest, if you fit a new sensor and same fault code is thrown up, you quesiton it, so fit another if they feel its the sensor, if its flagged up again then its obviously not the sensor is it? after 5 sensors surely it must of clicked that it isnt the sensor its self so why havent they checked the wiring and reported ok, thats what they say. So why not check the timing? These are ment to be "Master technicians" so why 8 times? They also have acsess to the Seat erwin system which guides you through
how to check the sensor so obviously they either dont want to know and are just after cash or dont know what there doing. My engine isnt running well and flagged the cam position sensor fault, but i didnt replace it, i checked and rectified the timing.
