Replaced my faulty inlet camshaft control valve -N205- as the electrical connection was snapped. This meant that the signal was intermittent, and on high boost the car would go into a kind of semi-limp mode!
was tricky to get out and ill need another screw as i dropped it in the engine bay somewhere. tricky one to fit that, what with a metal static pipe in the way. thanks VW.
