I have a ford galaxy 130 ps on a 53 plate it has an auxhilary engine heater that should cut in when the air tempreture dips below 10degrees c,some weeks ago it sometimes worked but bellowed out lots of black smoke from its seperate exhaust but now does not work attall.Just wondered if anyone else had had the same problem and knows what was needed to get it working again.
