I have had fault codes read recently as car was starting to play up a bit. It has identified cam sensor. I have ordered one and was wondering whether they are easy to replace or is it a garage job.

Thanks

Easy to replace, if you get stuck then drive up thr A46 and I will fit it for you.

Thanks Mark,
Is there a guide or is it self explanatory when you look at it.

Un plug the cam sensor wiring, then sketch the pulley belts location over the aux pulleys, then on the small tensioner pulley, the (small one on the right) use a socket + bar and turn it, the belt loosens, as if by magic !! remove it from the pulleys.
undo the timing belt cover torx bolts and nut and remove the cover
cam sensor is at top between the cam pulleys, have a good luck which way it fits and how the bottom fork goes on the stud sketch if required then undue the torx bolt from the sensor and it lifts out through the wiring hole, with a bit of a wiggle, drop the new one down the same hole ensuring its the right way and put the bolt back in, fit the timing belt cover, then lay the aux belt out over most pulleys and get someone strong and trust worthy to swing on the socket and bar to swing the "tensioner pulley" as you quickly thread the belt around pulleys via your sketch.
Once done, turn the ignition on and off 25 times to clear the ecu and start the car !
Top tip, buy the part from Vauxhall, the cheap italian ones suck !!!
Time, about 1 hour for your first one, 20 mins there after.
Difficulty level : beginner 2/10

You can get away without removing the aux belt, but you do need to undo the cambelt cover screws and wedge the top of it open against the aux belt, just enough room  

Turning the ign on and off multiple times will have no effect on clearing the code.......has to be done with cheapo tech2 or other diagnostic code reader/resetter

Thanks for the comments. Replaced it yesterday. I couldn't reach it without moving the cambelt cover as the bolt to undo the sensor is below the camshaft cogs. All done and light has reset so hopefully trouble free motoring for a while.
