I just brought a 2nd-hand Audi A4 3.0 Quattro for 1 day, and I just realized that I accecrate the car until 2000 rpm and let go the accerate pad, during the time it goes down to 1000 rpm, the rpm pointer is shaking up and down slightly, and I can feel the whole car is shaking. However, when it runs lower than 1000 rpm or higher than 2000 rpm, there is no problem. SO WEIRD! Btw,I have Audi 1 year warranty, so do you think is a small problem and also they can fix it for free?!

Hi rOn3oN,

Thank you for the donation.

Symptom indicates a fault with misfiring when decelerating and it could be anything from emission control to the engine controls.

As the vehicle is under warranty, you ought to go back to Audi to get them to resolve the problem. they should be liable for the repairs and it is good to get a written report for future reference.
