Throttle body adaptation is a reset of the throttle body flap to align it to the accelerator pedal as the TT is Drive-by-wire.

Its recommended to be done at a service and then always if the battery were to be disconnected, there are 2 ways to do it.
1. Switch on the ignition and leave it on for 30 seconds.
(You should hear some clicking in the engine bay, always after a battery disconnect)
This is not guaranteed to happen as the ecu decides if it needs doing,
if you disconnect/reconnect the battery first then this method will definitely work.
2.Use VAG-COM procedure as described below.

Engine not started
The coolant temperature should be between 5 and 100 degrees C.
Air Intake temperature less than 100 degrees C
Supply voltage to the ECU > 11V

Select Control Module

Select "04" Basic Settings

In the first group box type "060" and hit GO!

You should see the display below and watch the "Step count" step through until it reaches 8.

After doing this reset most people have reported better throttle response.
