You checked all the vac hoses, breather hoses, will more than likely be a leak, i'm currently chasing a few, there a nightmare.

Have you cleared the code?
does it come back?
Some members on here will be much better than me at telling you what the code means... or maybe check the code on ross-tech web site?

thought it might be vac leak but cant see any clear ones might have to have a good look when ive got time

You'd be surprised how hard it is trying to find them, i've just found one today on a pipe that i thought was ok, had 2 right splits in it.

ill have to have a good look ive heard there some fun ones under manifold did yours have the same fault code?

Didn't check the codes mate, just knew the car's not right, under the manifold are easy, its the pcv system one under the manifold that's a t*wt, couldnt be bothered doing it tonight so left it haha.
