Scirocco Central

My interior lights have failed (courtesy, map, vanity, basically everything except the footwell lights and switch illumination), it was working fine without a problem, and as far as I know in my year of owning the car, the interior bulbs are original.

Terminal 30 fault has shown up on my friends VCDS. I have been through all the fuses under the cover at the right end of the dashboard (UK/RH drive car), and also the fuses in the engine bay, not a single one is out, so I'm next guessing it's a relay, somewhere? I can see a load of relays behind the stowage compartment to the lower right of the steering wheel, but without a diagram I have no idea which relay is which, I'd rather not go pulling every relay in the hope it might be one of those, but if needs must...

If anyone has any ideas, I'd be most grateful...

You could try disconnecting and reconnecting the battery to see if it resets the CECM module. If you do decide to do this be aware that when you first start the car a few warning lights will remain on until the car is driven and the steering angle sensor calibrates.
