03 Relay 1000TD HDI SWB Van When I start van there's an amber icon on left of dash with a car & padlock which I've never noticed before. The van starts OK, ticks over and pulls away ok on flat but cuts out if pulling away on incline or above 2000 rpm. Once going sometimes runs ok, other times cuts out Sometimes engine management light comes on prior to cutting out. If I turn ignition off, lock & unlock doors it's starts again. Anybody any idea of the cause ?
