I am trying to work out some issues in the wifes car this week and on her 99 A4, the digital display that reads the gas mileage, etc has gone out. Is there a fuse that operates this? I know its a noobie question but her car is missing the factory manual. Or is there a bulb that works this? Or do i have to replace the whole cluster?

Thanks for the help,
Jive

Try hitting the reset button on the bottom of the stalk. She may have just accidentaly turned it off.
