I experienced this same problem but it was so erratic the Audi dealer couldn't duplicate or find the problem. I disconnected the tail light harness and found a loose/defective pin connector in the plug. I adjusted the connector pin for better mating. No more issues with this gremlin.

My flashers go on and off. It won't work for 4 to 5 time then no problem? Now, it's the left brake lith that doesn't work. I took it out to see. I didn't do any thing just put it it back and now it's working again? Love my car but audi's don't age well...
Turn signal is erratic. The flasher still works when the turn signal doesn't.
