You are most likely having a problem with abs sensor on one of the wheels.

it sounds like a sensor to me. when you had the fluid replaced did you use regular fluid that you would put into a gmc or did you put in the mineral hydrolic brake fluid designed specifically for the audi brake system. because regular brake fluid will screw up your entire braking system in an audi

I took it to a Goodyear tire shop, not sure what type of fluid they used.. most likely the standard type..

ok i made a boo boo the brake fluid is supposted to be dot 4 but as i said before it does take a not standard grade brake fluid and will screw up the brake system if the proper stuff is not used.
