I don't I know if it's all Audi dealerships, but my local Sacramento Niello Audi dealer was having a monthly special which happens to be 20% off parts and fluids when you spend $100 or more. This came out to be just $10 more for my drivetrain service (after the 20% off) than the cheapest online pricing I could find, plus I got a free hat lol. If you need any Oem parts of fluids, now would be the time to buy and I'm sure you could call in to place an order if your local dealership isn't running it.
