It probably won't. I've found out why it doesn't light up in the back and it probably applies to the front too.Not sure if my 12v front socket lights up tbh. Will check when I’m next home and let you know.
There is a light module called "spring clip" which fits around the 12v socket. This is missing on the facelift 12v sockets, and the reason its missing is because there is no wiring to that light on the 12v socket loom! There should be 3 terminals going to the 12v socket, but in the facelift there is only 2 even though the 12v socket has 3 wires coming off it. The light unit is about £10 from the dealers (part number: 4M0919340) and looks like:
Now, you can access the rear of the USB socket that's in the armrest and is illuminated via pin 4. I am going to splice into pin 4 and run it to the piggy back loom that came with the USB port kit. This should give power to the lighting terminal and provide power to the light terminal on the 12v socket.
I've got a brand new, 2nd hand 12v socket with the light module coming as I deformed mine anyway. The lack of illumination shouldn't bother me, but I've seen it now
