I was thinking of the CCM also, no water in the car, can it get to it from under the car?
I just noticed that the lights are on but barely lid, it's like they don't get enough power :s.
VAG doesn't give me any error, lol, except my rear tail light which i have to change ...

If i sort this out i'll let you know, thx pa4ul.
I hope I(or you or whoever seen this post ) do sort it out tho', it would make a very nice effect.

Thanks!

 

Oh, forgot, can i test the ccm somehow, to see if there are faults?

 

All the lights shown that are out are controlled directly via the dash dimmer. The radio, gauges, and climate control lights are controlled via their respective modules and only accept input from the dash dimmer. The window / door lock switches are part of the Daytime running lights and are on full brightness no matter if the dash dimmer is all the way down or not. My guess after reading this would be that your dash dimmer module went out. I don't know where it's located on your model but that's what i'd bet is malfunctioning.

 

So your saying I should test a new dash dimmer? ... or there could be a wiring problem between the dimmer and the lights.
Good one man, I'll try that out see if it solves it.
Will let u know...

P.S. my dash dimmer works tho', brightness for dash and radio decreases and increases when pressing - or + .

 

Correct me if i'm wrong here but in my Hanes manual, wiring schematics for lighting, there are no wires from the dash computer controlled potentiometer to the radio / climate / gauges. I'm fairly certain that these modules all receive their lighting data via the K band of communications, however all the others are simply bulbs. One thing to try is removing a vent, then taking it's red and black lead wires and supplying them with 12V from the battery, this would cause all the lights in question to turn on at full brightness, then you'll know it's not the lights, it's the main module's potentiometer.

I don't get it, what exactly do I need to change?
Is the main module's potentiometer the switch for each of the parts not working?
Or what is that?
Sry for beeing retarted on your comment

 

lol, returning back to the forum.
They all lighted up and when they did I changed the brightness through the +,- buttons and they turned off immediately so in the end I guess it's that module.

Is that the main module's potentiometer, screamin_demons?

Ty,

 

I have same problem my Audi A4 1.8 T quattro 6spd manual. How to solve it ? Can you reply back ?

My ambient lights are not working(sunroof switch,light switch,air vent regulators,lighter).
My radio,Center Console,windows switches lights are working but the ones listed above are not.

 

The intermittent issue with your Audi's ambient lights, sunroof switch, light switch, air vent regulators, and lighter suggests a possible electrical fault. Check the fuse box for any blown fuses related to interior lights. Loose wiring connections, a faulty switch, or a malfunctioning control module may be culprits. The fact that the lights worked briefly indicates an intermittent problem that might require professional diagnosis. Inspect the wiring harness and connectors for signs of wear or damage. If the problem persists, consulting an Audi specialist or auto electrician for a thorough inspection and diagnostic scan is advisable to pinpoint and resolve the issue.
