Did you swap the switched live feed and permanent live feed round when you installed the radio (all VAG vehicles have the live feed the opposite way round than other marques.

Yeah - It's usually a yellow and red wire that you hook up yellow to red, and red to yellow on the loom so that the radio's live comes from the switched live, not the permanent live.
