Fault come on dasch allways when engine is cold (after night ) and rev going to over 2000rpm or when i drive slow on high gear.Start flashing glow plug indicator for couple of seconds when i change gear and rev going down its stop flashing.but when engine is warm like 60 C i can accelerate how i want from 0 -4000rpm and fault will not come on dash.I was in the garage but there mechanics said to my everythings its fine :( its not because i got my car since new and newer was like that.PLEASE same one help me what i need to do ....
