My vans (1.7 DTi) engine management light was on when I bought it it stayed on all the time. The guy told me it was glow plugs and they had been replaced but it just needed vauxhall to reset the light on their computer.
Sure enough next day the light was out although when the van has been standing all night the lights on again (when cold) for about 5 mins then it goes out all day.
Was he talking tosh about replacing plugs or could it be something else?
PS if mine is an Astravan 1.7 DTi Envoy on an X plate 2000 is this an izuzi thingy engine 75bhp?
