Just been out to look, it's hard to see in these pictures, but no it doesn't light up. Turning the lights on manually illuminated the buttons above, the cup holders and the ring around the 12v socket.The one between the start/stop button the the 12 volt socket, should this be lit up?
I think so but the photos on the internet don't appear to have one fitted..
Earlier cars have both USB ports in the arm rest. These were then split with the one in the front. The front one is NOT illuminated. This is by design.
My 18 RS5 has the latter but my mates 17 S5 has the former.
