Hello... I didn't know where to place this post, so I guess tech swould be the most appropiate place. I have recently acquired a used A6 V8 and it only had one key. This is the master key w/remote (switchblade) and it is supposed to open and close my windows if I keep the button pressed (My previous Allroad did this from the first day) but it doesn't. Is there a way to program the key to do this? Also, anybody know how much it costs to get a second key? Thanks, Paranoico.
