i have yr2000 polo 1.416v but older model. i think its the same engine as golf. first started by cutting out when slowing down for junctions now sometimes it wont start at all. Garage started it on quick start and said it was a fuel problem and said fuel filter was full of gunk and replaced it. The day after its cutting out again. Somebody has suggested it might be the immobiliser and somebody else said its something to do with a sensor or module. Diagnosing the problem is my biggest worry as its expensive to keep trying different things and i've been told that it will not neccesarily show up on a diognostics machine as there are no lights coming up on the dash except the battery light which i know it isnt. Anybody had the same problem? or know any common faults?
