Camshaft sensor

[George Green]

Does anyone have a pre 2004 Astra 1.8. Mine is 2001.

I have trouble with the camshaft sensor which a main dealer tried to rectify by replacing. Unfortunately Vauxhall

do not make the part any longer  for cars built after 2004. Main dealer fitted two different makes of so called

compatible parts, neither of which worked. Had to revert to my old one being repaired. My worry is that if the sensor

breaks down again and the compatibles do not work, is that the end of my vehicle?

any help or info would be greatly appreciated.
