Had it diagnosed today and nothing, but he told my my airbox was missing screws which might of been letting to much air in, so I changed my airbox and screwed it all in, drove a few miles and coming to a stop at a traffic light and it decided to cut off again (always shows the ABS light when cutting out) and it's always when I'm slowing down changing gear doesn't happen when I just drive
Anyway I also changed the battery fuse box as he said it had been bodged and there was a fuse missing, so replaced that and drove about 10 miles since then and hasn't cut out, I still reckon tomorrow it'll cut out but so far so good.
Does anyone have any idea what could be causing this if the battery fuse box hasn't cured it? Nothing at all comes up on Vagcom!!
