Here's a few:
- rain sensor closing (windows & sunroof)
- DRL'S via fog lights or indicators
- unlock all doors with one touch
- teardrop rear wash (can't remember what this is
)
- beep when lock / unlock
- adjust number of flashes indicator does when tapped once
Also on Mk6 golf / Scirocco from Feb / march 2010 you can activate XDS - all of them have it as standard (dealers charge £240 to fit as an option)
