Anti-dazzle light issue

[complexsquid]

Hey guys

I have recently got myself a 2008 Audi A5 B8 3.2 V6.

I have noticed my rear vision mirror ON/OFF lights are not illuminated and its quite clear its doing nothing while driving at night.

I have held the ON/OFF button, does nothing. I have not noticed anything else not working like the auto lights etc so I am doubting the fuse but if someone could let me know where this damned fuse actually is I will happily check. I have had a look around both interior fuse boxes but none of the fuse titles explicitly say Anti-dazzle or similar.

I have seen threads talking about the coding of the light....this is far beyond my expertise so if it leads to that I will just have to take it to the shop.

Thanks in advance for your help!

Ideally multi meter on the wiring, if it was working before, then its most likely wiring/fuses as they don't really go faulty, if not able to check with a meter, pull fuses to check them all on the side of dash or under bonnet.
