Hi have a problem with van cutting out been on different plug in units does not show up fault code, van drives fine pulls like a train, then for no reason will cut out , glow plug light comes on, flick key engine starts right up then will be fine for a day or two, have replaced , crank sensor, some relays, blanked off EGR valve, going to try cam sensor next, just going through things that are easy to replace, been in garage for servicing , mots . spoke to other Mechanics no one can say what is going on, So maybe someone has had the same problem ?????????????
