I got my first A4/car ('09 Audi 4 3.2L Quattro Prestige) about 3 months ago and for my first car ever, I am very satisfied. In the past three months, I've put 3,300 miles on it and got my first oil change. It's pretty fast and it's so fun to drive! The only thing I can complain about is the gas mileage. I'm only 20 years old so money doesn't come easy but it sucks because it seems like I get 15 mpg. Anyway, I love Audi and hope to stick with Audi for the rest of my life. Side note... My check engine light is on and so is the EPC light, the car has been shaking. It doesn't always have the lights on and it doesn't always shake. Only sometimes. Anyone have an idea as to what is going on with my car?

You will need to find out the codes that are stored.

Since your fuel mileage is horrible, I would suggest doing that soon. A bad O2 sensor can hurt a catalytic converter and cost you much more than sensor alone.

Head to your local Auto parts store and have them check those codes ASAP. If you can determine the problem sooner rather then later, it will save you $$
