Apologies for the thread highjack, but I've a related problem here with my 02 Passat.

Normally 2 keys I've got, when you unlock the car with the fob all doors unlock. For no reason I can think of, they both now only undo the driver's door. To get the rest to unlock I have to open the driver's door, then hit the main unlock button on the door card. A pain in the arse when you're wanting to just open the passenger door...

I've not Vagcom, or at least not got a working version
