2011 Audi S3 Traction control, can it be turned fully off
Discussion
You can turn off the ESP (button in centre of dash), but as others say the Haldex essentially shuffles power between front and rear axles depending on slip - so, no, not really in theory!
If you have a post-2009 model with S-Tronic, remember that the gearbox features launch control which essentially consists of: pull up, hold car using *left* foot to brake, shift into "S", turn off ESP, depress accelerator to about 3,500rpm, take foot off brake and go...very quickly.
If you try to launch from standstill with ESP on, it usually bogs down. I was doing this for a few months before discovering launch control - little else on the road will match a combination of a dual clutch 'box, launch control and 4WD.

That's me sorted for something to go and have a play with tomorrow am.
The ESP button on the dash disables the anti-skid element of the ABS system - which is in effect the vehicles 'traction control'
The Haldex unit operates to its own logic defined by its software.
The 'bogging down' effect you feeling is another component of the anti-skid braking sub-system, namely the EDL - Electronic Diff Locker - which tries to simulate a mechanical diff locker by braking whichever front wheel it deems is slipping upto speeds of 50mph iirc.
The S-Tronic featured mentioned preps the DSG, disables the EDL + anti-skid & engage the Haldex clutch iirc
If you want your Haldex system to operate a little bit more like a conventional 4x4 you need to invest in a HPA Performance Controller.
This will engage the Haldex clutch on acceleration, rather waiting for slip. It will also engage the clutch faster.
The blurb on HPA's website explains it.
