B9 My new to me Navarra RS4

Not sure if my 12v front socket lights up tbh. Will check when I’m next home and let you know.
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.

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:

1762535178248


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 :wink:

Jus fitted mine today (2020 B9.5) and my rear lighter socket has that light up part and the usb-c socket lights up also (not the USB-A though)

I guess it’s part of the comfort and sound pack

There was some minor changes on the 2021+ models or could have been impacted by the chip shortage in pandemic times too

I have the comfort and sound pack but no light up 12v sockets. I’ve bought a front 12v socket that lights up to retrofit but haven’t got round to it yet

That's a bigger problem than you think lots of cars had bits missing or 'cheaper' options fitted, whatever was on the shelf. I would be more worried about the pistons in the engine than a lit cigarette lighter. To be fair not just VAG group at this sort of thing at the time.

Yeah that is a concern, so far it doesn't look like the RS4/5 engines are affected by the piston skirt issues despite being in the same family as the S4/5 engines. Time will tell...

As far as I can see it is only the 3.0 DLZA that has had the Taiwanese pistons fitted, hopefully the DECA escaped, but as you say time will tell.
