I have a 99 Audi A4 Quattro, and latley for some reason the car will go through a tank of gas in 3 days, with no long trips or excessive driving. It used to go atleast a week and a half to two weeks on one tank of gas with relativley the same amount of driving. What is wrong with my car?

If it has one, it sounds like the fuel press regulator might be leaking fuel into the engine
