Xtool V401 Using Tips 
Prime Fuel Pump after changing TDI fuel filter:
Diagnose > Common System > 01 Engine > 04 Basic Settings > 035 : Pump runs for 30 Seconds.
TRANSMISSION - Reset DSG Adaptives:

Transmission Tolerances (Engaged Calibration):
@ Operating Temp > Park > ER/Hand Brake On > Key On > Diagnose > Common System > 02 Transmission > 04 Basic Settings:
061 > Wait for any numbers to stop changing > Start Car > You'll soon feel the gears cycle, wait for all #s to stop changing > ENTER > Engine Off
(8/30/15) Mine settled at 141, 128, 4, 1

Transmission Tolerances (Synch. Point. Measurement)
@ Operating Temp > Park > ER/Hand Brake On > Key On > Diagnose > Common System > 02 Transmission > 04 Basic Settings:
060 > Key On > Wait for any numbers to stop changing > Start Car > You'll soon feel the gears cycle, wait for all #s to stop changing > ENTER
(8/30/15) Mine settled at 13, 0, 4, 1
DONE, release hand brake, turn car off or drive.

065 (Clutch pressure), all showed 0.00 PSI running or not, so do not know if/how reset.
062/067 - Clutch Adaptation, those numbers did not change. 062 is if Control Module Version is => 0800, else 067.
068 - Clutch Saftey Function, those numbers did not change either.
063 -Reset Values (Steering Wheel Paddle Installation); did not use.
069 -Reset Values (ESP & Tip Cruise Control Installation); did not use.

Windows down via Keyfob adaptation:
Diagnose > Common System > 09 – Central Electronics > Adaptation > 006 > Change 0 to 1 > ENTER
Disclaimer: May be an issue where it sometimes won't let you navigate to Channel 006. It seemed like this issue was prevalent if I you have been
fiddling around in other function areas. However, if you navigate straight to Central Electronics / Adaptation from plug-in, this should work.
