dash lights

I have a 01' TDI VW Golf, last night all the dash lights stopped workng.
Everything in the dash works, clocks, radio etc, but the background lights are all dead. Anyone any ideas.

Check the fuses, I'm not sure which one is for the dash lighting but, it may be blown. After that, I'd check the connections on the dimmer switch to see if it came loose.

I think it's fuse #1, all run through the dimmer switch.
