Vcds?

Anyone on here play around with VCDS coding on the Q3 yet? I'm interested to see what is possible to enable via some simple coding changes.

For those of you that don't know what I'm referring to: http://www.ross-tech.com/vag-com/index.html

For example, on my 2011 Volkswagen GTI I was able to enable a gauge sweep when the ignition is turned on, rolling up/down the windows via key fob, disabling the daytime running lights, and enabling the European headlight switch for city lights and rear fogs. There are tons of other possibilities hidden within this program, I'm excited to see if anyone on here finds any hidden gems I might be investing in a cable soon for both our cars, so I'll update if I do & find anything neat!
