Default Sluggish Acceleration

I have a 2007 Audi A4 automatic with 59k. I have been having trouble accelerating for a few months now but only when at low speeds. The rpm sticks at 2500RPM and will not move unless I push a little harder on the throttle to get past it. It is much more noticeable with the AC on. It also feels very sluggish below 3k like trying to take off from a higher gear (2nd) in a manual transmission.

Please help this is very frustrating and The Audi dealer is saying nothing it wrong with the car but it never used to do this.

Might need a throttle body adaptation. not sure if it applies for the automatic but you turn the ignition on, (don't start the engine), push the throttle down as far as you can, turn the ignition off and wait 2 minutes.

VCDS has a procedure for doing this as well.

See if it does anything for you.

Tried this with no change in how the car accelerated.

I had this problem, swap the fuel filter out. My car runs like new now. Previous owner had never replaced and it had about 100k on the original filter!

Make sure the PCV system is functioning properly.
