Danskidan Posted January 3, 2018 Report Share Posted January 3, 2018 My 1.4 se 75bhp has just failed MOT on emissions, hydrocarbons too high, possibly over curling? I changed the throttle body couple of months back and since have noticed a drop in fuel economy. I've had error p1554, does this need plugging into Vag-com to sort it? Does it need the throttle body aligning properly? Thanks in advanceĀ Quote Link to comment Share on other sites More sharing options...
