2005 A4 Drivetrain Question

I have just started taking my 2005 with 4 speed auto to the track for autocross and road raceing. My first trip was at VIR and I had problem in the turns of losing the transmission. Good RPM just nothing going to rear wheels until I got it straight. Today I was doing some low speed autocross and had the same problem. Eash time I went into a turn nothing to rear wheels until I got it straight. Had the car to the dealer with no help. Does anyone on here have any idea as to what the heck is going on. I also drag race the car without any problems.

it works that way because of the active handling and traction control, i turn the ah&tc off, but i think in road racing you need competitive driving mod

I turned off everything I could find and still had the problem.

I am gonna guess and say you were running it in overdrive vs. 3rd. Right?

You need to not run it on the track in overdrive. This sounds like what I discovered early on when I got my 05 A4 when I came into an interstate on-ramp hard . ... same symptoms .... one of the vette engineers I spoke to at BG told me for perf driving it should not be in overdrive.
