so on my b5 the light on the clock on the instrument cluster went out about a week after i got it. no big deal i think it looked better since i dont use it and have a dvd player w the time. but a couple days ago the 60-120 lights on the speedometer went out. anyone know if its just a bulb or do i have to replace the entire cluster? if i have to replace the entire thing, can you set the milage back or only forward?
