This thread could make confusing reading because there are 2 seperate issues being discussed:
VW 'One Touch Control' is fitted on all EOS's. This is the feature that allows you to press and hold the window button a short time and windows will motor to fully open or fully closed. This is most important on the driver side for pay booths etc or waving at your mates.

. The same thing happens with the sunroof. If this function is not active the windows buttons work just as on/off buttons. Whenever you disconnect the battery, the One touch feature is always lost, but it doesn't stop the windows or sunroof working. This is what most mean when they ask about 'windows reset'. I can't remember if One Touch Operation needs to work for roof operation? The sunroof is curious because sometimes it can get out of sync, half open or close or not fully close when you operate the switch, The windows reset fixes this.
I have to admit that windows One Touch Reset on MY07 has been something of a hit and miss black art in the past but I've never resorted to vcds to try the reset, I don't think it's in there. First I try the procedure of taking the windows right down to the service position, hold my finger on the switch for a couple of seconds, then take the windows right up to the top and hold again.
Most times that has worked but the last time after a battery disconnect it didn't and I had to use the key method and all was well. However, it occurs to me that if for some reason there's a windows fault code logged that might stop you doing a reset?

When you have vcds it's easy because you scan then reset any flagged codes and if they come back you know there's a real fault to look at. Windows reset is in the manual, follow their instructions exactly - They do mean close all the doors, it doesn't work with the driver door open!
All I can suggest is you disconnect the battery for 1/2 hour, connect it back on the last terminal quickly without arcs and sparks then check all the windows work on the manual switches. Now try using the key. Note that disconnecting the battery does not reset fault codes, it's like a reboot which sometimes give you a fresh start.
The second feature is being able to hold your finger on the remote key fob button e.g the lock button and as long as you hold it down, all windows will come up. Conversely, if you hold your finger on the unlock button long enough, all windows will come down. THESE FEATURES OF REMOTE WINDOW OPERATION HAVE TO BE ENABLED WITH VCDS. On higher spec. and newer EOS's you may be able to do this through the MFD option settings - I can't.
