ok here goes,now need some advice, the dealership have said that because the aux booster heater is an accessory they will do nothing about it,so i went to the supplying dealer and had a polite conversation about this matter,and he has said his hands are tied basically,have also contacted trade and standards people for info, is the booster heater regarded as an accessory?technical info needed on this one does it harm the engine in the long run if its not working? need help from you good people on this b4 i really blow my stack over it,i know the car drives fine without it working,but in my reckoning if it was there from the day the manufactures put it in THEN ITS THERE FOR A REASON so it should be working thanx good peeps regards gregers
