A4 B6 2003. Interior lights not working at all ( dome, glove box, footwel lights ). All fuses are good. Dome lights not working when door opens, not when press dome on/of switch. But, trunk lights, two of them are working normaly.
I have searched many forums and found that my be problem with CCM module, but if CCM module is bad, even the trunk light would NOT be working, but they work.
Thank You for any suggestions where to start

I am in the middle of troubleshooting a similar issue, but mine is my headlights don't work. I ran some voltage checks this weekend and found no voltage back to something called the J519 module / Vehicle Electrical System Control Module / CECM.

My quick review of the wiring diagram says the interior lights go to the Central Comfort Module which is under the drivers seat and is prone to getting wet. I didn't see the dome light anywhere on it, but the footwell lights are on page 16. See below for a link to the wiring diagram. Maybe that helps.

Finaly I found the problem.
There was shortcut and few melted wires and main connector in dome lights, some cutting and soldering and problems solved.
So simple.
