“Throttle response mod”

Open VCDS / Select / 
  44 - Steering Assist / 
  Security Access / 19249 / 
     Do It / OK / 
  Adaptation / Channel (drop down menu) / 
  Driving Profile Switchover / 
  New Value (drop down menu) / 
  Direct: Controlled over Threshold Value 
  (original was Gradual, controlled by Time) 
  Do It / Yes / OK / Go Back / close, go back etc.

THIS DOES NOT CHANGE ACCELERATOR RESPONSE
I think it actually does absolutely nothing on any TDI, because our cars don't have adjustable steering response
