I had a glow plug warning light flashing and a red oblong warning light that is on constantly.After realising i had a problem with the turbo actuator arm,which i have now solved which in turn as cleared the glow plug light.Every thing seems fine now fine on tick over no smoke and sounds good etc.The only thing i have now is the red oblong warning light is there any way to clear this with out taking car to garage as a body repair i am on with is not yet finished also car is not legal to take on road yet.Hope some one can give me another option thanks.
