Just had an expensive and really irritating failure on our Autotrail / Fiat Ducato 130 Multijet. I had travelled about 200 miles in one hit and just before the end of the journey diesel started pouring from the fuel filter. The fault seemed to be a pipe that had become partly detached as refitting it appeared to cure the leak. In fact it held for the next 180 miles then the leak started again with a vengeance. This time it would appear that the housing is cracked. Currently the MH is at a garage where every one of the mechanics seemed to know that this is an ongoing problem / defect with these units. I am expecting quite a large bill to add to the cost of fuel lost and the need to give our wagon a good clean. Why do motor manufactures not recall, rectify the mistakes they make?
