Well I cleared the fault before setting of on a 80 mile trip, no flashes of glow plug light all the way. Car behaved great. Pulled it to services, quick coffee and back on the road. Three faults in the next 2 miles. Only seems to fault at slow speeds and when hot. Any ideas where to start because I am lost. Thanks Nige.
