If i try and put my foot down the anti pollution fault light comes on. If I just drive around and gently pick up speed light doesn't come on. Once on there is no power if I put foot down and if on motorway car won't go over 70 (unless going downhill). When had MOT the garage ran a diagnostic test and results pointed to a fualty switch but haven't got back to me. Have spoken to 2 Peugeot garages about this but somewhat disappointed with answers. Anyone got advice, ideas on what I should do (apart from sell car!) before I go back to dealer?
