I know what the trunk button is for, and the motion sensory disable, but there is a button between the that has a small dot and sound like wave coming off it. What does that button do? And, is there a way to open the windows with the remote?

 

P.S. I have a B6

 

i kno in my car if i hold the key in the unlock on the door the windows go down so try holding the unlock button in the remote and see if it happens.

 

You need to have a mod done via Vag-com for the key to work opening and closing windows. I had it done to mine, and it is very convienient.
