[Josh1994]

Hi all, as you know i have just posted a thread about a saab which i had a problem with and now i got another problem with a vauxhall vectra 2.2 diesel elite which i brought for £695 with a spanner car light on thinking it was an easy fix, i had changed the glow plugs and changed the camsharft sensor, after a couple of days the light came back on then i called the rac breakdown service which cleared the code and same thing the light came back on, i dont know what eles it is either than one of the wires is dogdy? Any ideas? I would appreciate the help.. thanks..
