Dealer say maybe I'm buying 'old' gas.

I hope you are paying old prices for it.

Me thinks your dealer isn't doing their homework on this one...

Bad gas, wrong gas station (I love that one, the car will run with Mobil Gas but not Chevron), the A6 guys get the tires are defective that's why the car vibrates.

What's the code that is stored? That's the real question.

In my A6, they kept BSing me until I retrieved the code showing a failed O2 sensor.
