My 2013 fabia vrs estate is running a little off at the moment. Slightly erratic idle, seems a bit hesitant on pick up, gearbox seems a bit slow to react, so I suspected a possible vacuum leak. When I've connected  my gauge up to the engine I am getting absolutely zero movement on the needle unless I blip the throttle and then it moves slightly into positive pressure. Do any of you fine chaps have any idea where to start looking first?

Best get your mechanic mate involved again.

I would if he hadn't gone to the match.
