      It's one of them codes that could be many things, really annoying. I've never had that code on mine but a few months ago I did find the breather pipe was loose where it screws into the inlet manifold. It's probably not likely as mine wasn't sealed, although there's no harm in removing it, cleaning it up and putting it back nice and firm. At least that eliminates the chance of it being the problem. Hope you get it sorted and let us know how you get on.
