i have been using my laptop to reset my suspension ect for a while with no problems but i now have my warning bleep coming on within 300m when driving off and continues every 5mins.my suspension is working fine-goes up/down and stays up over night.unfortunitly both bulbs have gone on my display(got told it was a hellish job to strip the dash out so have never got round to it)by the time i pull over to try and read the display it is normal or has the 35mph up.either way i can still check mpg milage ect.pump does seem to be on a while but no faults being registered on the laptop !!! pulling my hair out now-can it be a dodgy door sensor or something?
