If I understand your post, the lights on the headliner are the ones with the problem... If so, from the Wiring Diagram, and the description of the lights that are flickering, it may be the Function Control Center that has an issue. I do know from replacing the headliner bulbs with LEDs that this is not a straight +12v drive for these lights, but a PWM output used to vary the brightness. You might have a look into the output of this module instead of the FRM.

Hope this helps,

That's what we replaced in our a6 and it fixed the problem, as since it controlled the whole cars inner lighting we guessed that it may be the culprit and it fixed everything. May be worth a try.

Try eBay or take it to the dealer for them to try one from another car to see if it helps.

Anywho that would be where I start.
