   - The only true way to reset Tiptronic adaptation is to use a VAG-tool. The above procedure only resets the car’s maximum throttle position (hence pressing all the way down to the floor).

   Here’s an interesting discussion about Tiptronic acceleration on Vortex. It seems that the ECU does not apply acceleration if it thinks the brakes are being applied. There may actually not be anything wrong with your transmission, but rather behind the ECU and its sensors. I’ll dig around a bit more about this, but considering you probably already exhausted your mechanical options, this may be another line of investigation you can pursue.

   Reset Tiptronic – Meant to post this as well. I’ll try it tomorrow:Resetting the Adaptive Automatic Transmission

   This one:
   To reset your transmission to basic settings:
   1. Turn the key to the on position.
   2. Press the pedal all the way to the floor (Past the kickdown)
   3. Hold for at least 5 seconds
   4. Turn the key off”"

   OR this one:
   1) Insert key and turn to ‘on’ position (do not start car)
   2) Fully depress the accelerator twice
   3) Start car without turning the key back

   I know dealer reset for me months ago but didn’t seem to fix.

   - That is interesting, thanks.
   My transmission problem ‘feels’ mechanical but it could be pure ECU.
   I once thought it had to do with the car heating up… but follow this logic:
   I thought it was heat / mechanical related because I tend to notice this sluggishness after a long drive (30-45 minutes). For me to do a long drive means I am getting on a highway. To get on highway I often hammer the gas pedal. After doing that I wonder if I am messing up the ECU… I get off the highway, obviously need to brake at some point, I tap the gas and get no response for a few seconds.

   - Simple test. In a quiet street where you can test acceleration in first gear safely, hold the brakes then switch to the gas and detect hesitation. Next, do not hold brakes (which on autos means you roll a bit) and after a few seconds hit the gas and see what happens. I might even see if there’s less hesitation if the car is in neutral and shifted to drive as you hit the accelerator.

   You really won’t be able to confirm if your particular problem is the ECU without using a VAG tool of some sort (like everyone’s favorite, VAG-COM), to check if the throttle body opens at all when you hit the accelerator, and also to check if the brakes are still detected as applied. But the above test might give you an inkling.
