Audi A4 2008 S Line B7 Interior light problems

[slytwyn]

I was changing my interior lights to new LED ones and all the sudden they stopped working. I believe I have blown a fuse but I'm not sure which one or what to do about it. If anyone can help me it would be much appreciated.

Do you have the owners manual? I had the same thing happen to me and it was the footwell fuse that blew.

I checked the central convenience electrical fuse and it doesn't look blown anything else it could be?

Did they all stop working or just one?

There are 2 fuses if I remember correctly

[slytwyn]

The dome lights, the glove box and the mirror lights don't work.

24 and 38 I believe

Inside the fuse box you should have a map to guide you

I checked those and they don't look blown, could it be possible that they don't look blown but are?

Well, they will be blackened and or have a broken tab if blown. But yes, ive seen fuses look ok that have been bad. If you have some time and still can't solve your issue, id zip over to the store and pick up some fuses. They're dirt cheap

Just remember LED's are polarised. They only work in one way so although this doesn't sound like your issue, make sure you install them correctly.

It was a number 38 a blown fuse. I'm not sure how I missed it enforce but I replaced it and I'm good now all the interior lights work

thread revival ! because search ...

Issue : No dome light , no glove box light, no door chime , no sound at all on any alarme (burn light, low fuel, light ON when car's off, etc)

- I have a full interior led, and the glove box led burn out and the relay starting clicking when the car was off, and doors unlocked .
- fuse 38 is ok
- footwell light are OK (ON with doors open)
- some times , dome light are flashing when doors are open. (fuse ok, door sensor OK )

Guess : the relay might be burned/damaged.

[Q] : - where's that dome light relay?
- Why I have absolutly no chime sound ?


thank you


Guess no 2 :

CCM PCB. Does B7 got those ccm?

^^ bump, before I remove everything

Bumped thread because I need help too. Upper dome lights and visor lights don’t work. Glove box light doesn’t work. Backseat headliner lights don’t work. Footwell lights do work when the door is open. Door puddle lights do work when the door is open. All fuses look okay. I had led lights in them all. They all worked great for several months. Eventually dome lights started flickering and then eventually this happened. Fuse 38 is good. Swapped it with another fuse just encase and it still doesn’t work.

same issue, I'm way too lazy to start the job, but basically it should be a short in one or more of your lights (remove all light and put back one by one. Or the comfort module relay. Its located on the driver side next to the hood latch handle.

Since I do not use the car when dark, I just didn't take the time to look at it.
