No replies so I dug in and here's what I found.
I pulled the hazard light assembly out which also houses the binker relay; this is located in the upper center of the console just under the dash air vents on my 99.5 facelift A4. Using a small screwdriver I popped the back cover off the switch assembly and could clearly see the two relays; the one with two contacts is for the hazards and the one with a single contact is for the blinkers. Looking close, I could see the contact in the blinker relay had some flashing or burnt material built up; it's hard to get at but I used a small craft exacto razor knife to scrape the surface of the contact smooth and then sprayed deoxit gold contact conditioner on it. My blinkers have not stuck on since. This took about an hour and cost $0.
