Ok, I think I have tracked down the electrical gremlin.
Sooo....the side mirror indicator is lighting up on the part you can see from the drivers seat, but upon closer (and repeated) inspection the whole LED strip was not lighting up...and moisture inside the light housing.
I guess this weekend I am opening it up and trying to dry/ check/fix seals and hope that it is salvageable...if not i guess this is a sign from the Audi gods to get some sexy aftermarket dynamic signal lights.
I know this thread is not as sexy as anything that makes our cars go faster, so thanks to everyone for the suggestions, this forum and community are a great resource.
