Problem bogging down out of 1st and 2nd

[DZA]

When I accelerate hard from a stop, the car will start to take off, then bog down for a brief moment then take off again. The same thing happens when I shift into 2nd. Perhaps a better way to explain it is that the car jumps forward once I have shifted and started to accelerate again. After it jumps forward, it acts as though I took my foot off the gas and takes off again.

It’s AWD so I SHOULD be able to dump the clutch from a stop with no problem. To remedy the bogging down, I have to keep my foot on the clutch pedal a little longer and it is certainly pointless b/c I’m already in gear and I shouldn’t have to ease off the clutch like that.

I have no relevant trouble codes, and I ghetto fab’ed an intake on b/c I THOUGHT the dirty stock box was the problem. I had a good amount of sand (no idea) in there.

Is this common?
Is there anything I can do?

I have a 2003 A4 3.0 Quattro mt… not sure if its in my signature.

Dan described it pretty well. I couldn't figure out what was up with it when I drove it last night (which isn't saying very much...). Any ideas?

People on an audi forum think it was ESP getting in the way. I suppose if the computer senses loss of traction, it will limit output... they explained it better, but basically the computer says no and bogs down.

I turned ESP off and it was better but it just doesn't feel right. It feels like there is resistance shifting in to 2nd and its still bogging down.
