Reset light service required on bentley arnage red label 2000

Its been a while but there should be three buttons that you can go through your trip mileage etc. the two on the outside I think they were a plus and a minus sign. with the key on eng off hold the two outer buttons and the dip should beep and then go into a setup menu where you can go through different things on the dip. go to the service reset portion and hold one of the buttons in until it beeps and it should go from red to blue or vice versa. and then check the outcome by turning off the vehicle and starting it see if the service is still on. if so try a different button. hope helps
