Default Lost horn,interior lights and glove box light

Hello friends.First,sorry for my bad English. I have problem with my 2011 Audi A6 2.0 TDI 177HP
I hope so you are help me to solve my problem. I lost horn,glove box light and sun visor lights
when i buy car, there was instaled LED interior lights, only glove box light wa been yellow halogen light so i buy LED CANBUS bulb. I replaced the bulb but it not worked. I put back old halogen bulb, but that bulb isn’t work no more. I try new bulb but the same problem. Then i was spotted that horn and sun visor lights are not working. The other lights work perfectly. I check fuses, try out with test lamp and they work perfect too.
I dont know where the problem is. I was checking and there was few same problems on this forum too, but there are no answer what the problem is
If I make a mistake some in text,sorry!

Do you have a VAG-Com or know somebody who does? Most errors of lighting show up as errors to help with diagnostics. Having said that, I suspect a fuse somewhere. My knowledge of fuses is minimal but hopefully somebody gives you relevant feedback or your fuse research narrows down the correct fuse. The canbus cannot be broken as you would lose lots of features.

haha good luck with that! I had that after messing around with lights options and NOBODY knew anything. Weird part was that my glove box light would work but as soon as testing come to test terminal 30 light would turn off and code come up. Somewhere i read about different bus or wires (dont remember exactly) are utilized to run communications between modules, so when it's crossed or used at the same time it will cause an issue. I think that could be the case for Terminal 30 error. My fix was to return all setting back to original set up
