Car Just Doesnt Seem To Have the Acceleration It Use To
I just filled my car up and it seems sluggish. I dont know if the pump didnt give me premeniun like it was labeled or something else is going on. 2nd, 3rd, and 4th just dont seem the same. Could this possibly be a turbo problem. Any help is appreciated. Thanks

I've seen where people have gotten a fresh tank of gas, but in reality, they got......
the "bottom of the tank" from the gas station, which in reality was a lot of muddy water. If this is your case, you're engine will eventually not start, or a cel for misfires & system too lean/rich will result. Could potentially be a long diagnosis for an audi tech. Be sure to tell them it started after you filled the tank! Also, you may end up paying for it, let the gas station management know of your problem as well, and when it's done, take them the bill.

The car is starting right up without a problem. Is there anything I can do to check the content of the gasoline or should I just take it into the dealer?

You can check knock sensor values with a VAG, read data blocks.....
20, 21, 22? Might be you got the wrong octane, you'd be alright to just run the tank empty, or add some octane booster. & make sure you get good stuff next time. Dealer should be able to tell you if you have lower octane fuel, but I can't vouch for all techs at dealers.

Is it possible to empty the tank without putting miles on the car ? Although it would be fun to take a whole to drive around and drive the engine down, I would rather just get whats in the tank and try refilling it.

Here's a quick, easy procedure to empty your tank.....
-pull the fuel pump fuse.
-crank the engine until it doesn't even fire, to eliminate fuel pressure in the lines. Do 5-10 second cranking.
-Key off. Disconnect fuel return tube, pinch off rubber line, install 3/8" hose to fuel rail at return port, and route into container/kiddie pool(J/K!)/other car/what ever. Scratch that. Make sure to use an appropriate approved container, or just put it into another car that's not so picky about octane ratings. My poor attempts at humor could be misunderstood here.
-reinstall fuel pump fuse. Key on, check for fuel leak. None? Start car, fuel should come out of your 3/8 tube into your container, and continue until the tank is empty, & engine dies. May set CEL for misfires/low fuel.
Insert appropriate disclaimer here. Gas is flammable, combustible, & dangerous! :-O Proceed at your own discretion!
