Sounds as if you have knocked something out of place, take plenum cover and shroud off again, check around, check wiring loom in that area, they are know to be fragile, on passats anyway. Check connections to ecm etc, probably something silly, and you will kick yourself when you find it. Just have a good look around, move things, anything that moves, suspect it.
