Thanks!

It is a known resistance issue between the AS's LED's and the GL's LED's (apparently there is none, or something to that effect).
However there is a fix! Go to your VW parts store and explain your problem. They will sell you a short cable (about two feet) with built in resistance and plug that cable into the GL's 7 pin, and then into your AS's. The problem will magically go away. The cost of the cable from VW is approx. $40.
