      For that to work you have to let the car sit until the motor is cold. Not for 2 hours cold, but like 10 hours over night cold. Then immediately get on the highway, hold 65-70 for a minimum of 5 minutes and let the car decelerate on it's own down to about 20.

      If you have access to VAG-COM, you can use one of their scripts to set the readiness bits.
