This guy lists A4 B7 as being compatible - they look to be the newer flush fit kind (don't have the extra surrounding ring) - but I can find nobody else backing up his compatibility claim. They are obviously physically different but may still plug into a B7 rear bumper that has smaller than usual holes drilled do you think? Chances of the A4 B7 factory PDC still talking to these? Anyone got any ideas or already been a guinea pig?
