Sluggish Acceleration when Air Conditioner on
I love my Audi but when the air conditioner is on there is a huge flat spot. Does anyone else have this problem with their Audi A4?

with any car there is going to be some loss of performance with the AC on
Do you have a 3.0 or 1.8T? If you have the 1.8T the AC + some turbo lag could be what you are experiencing.

What you are experiencing is true for any car...
we actually did a problem about this in physics class back in the day. If i remember correctly, having the air conditioner on full blast can have the following effects on the overall power of the car (moving the car foward):
-minimum "power" consumption: 12%
-avg consumption: 16%
-can take up to 30%!!
and as you may have guessed, the air conditioner has a parallel effect on your mpg.
So yeh, since then, whenever I want to be quick, the air goes off.

actually might be a failed temp sensor our a/c is variable geometry
If the demand load is low for a/c the a/c compressor somehow magically varies its displacement to reduce load to near zero loss when cruising at a steady state.
if its ***** blasting hot outside, sure it will be working 100% to help you out.
probably why the a/c compressor costs nearly a grand to replace lol. gotta love high tech stuff.
