Ok here is my problen I am getting a cam position sensor issue when plugged into my mates snapon reader and reading all the forums it says it is a timing chain issue, yet my car has power, does not miss a beat the turbo kicks in and i get the usual voomph,,, this car drives like a dream... so if my timing chain was loose or stretched, would i not get all these or at least some of the issues mentioned...oh and it does not rattle on cold start up?

problem 2
i am trying to buy a cam position sensor and can I hell as like find any in stock... any body got one they can sell me or direct me to the right place where i can buy one...

I thought I would go the cheapest option first before comitting to a new chain kit,,, depending upon your answers.. it has done 140k so it maybe could do with a new one?

many thanks...
