Hi, led for needle ( blue ones ) goes off, all four needle ( 6x LED ) after weak. You turn the ignitio OFF and ON, and it works again for a few days. 
Has anyone encountered this before?
I'm trying to fix them but they don't do it on the table.

Dash 5K0920870G

i had trouble like this before on audi a3 8p with white dash but i had a fault for kombi ( control unit malfunction ) my fuel low light would flash, i removed the cluster and resoldered all the connections on the board where cables connect and fault went away, also you might want to check coding with vcds, my 8p was set so the cluster would dim down in bright light and brighten up again in the dark, the cluster was set to adjust with the light sensor on the dash, the setting was something like this
( needles and scales on via light sensor ) i changed coding and the dimming stopped, goodluck

I finally got the dash, I heated individual LEDs with hotair and some one went off. I replaced all (6) just to be sure, so far it's OK
