Just to confirm, it flickers intermittently all the time regardless are you using only drl or low beam?

Audi dealer did what, just diagnose with VAS tool ?

No need, they probably did not dismantle cluster anyway.

Behind rev needle, there is 3 leds each has own resistor. We dont know flickers one or all 3. Its not hard to dismantle cluster and any computer or "home-electronic" repair are able to replace those, parts cost is nothing. My guess is some led or resistor is failing or cold-soldering point. Put if somebody already will go in, its safe to replace all, after this is done, you can safely connect only circutboard and test if flickering is gone or it flickers only one or all.
