I have the same problem right now. I called Audi, they said that it would cost $130 to fix, I do not want to pay that. I checked all my fuses, they are fine. So I'm thinking about doing the whole removing the radio thing. BUT, Audi told me that the only way to fix the turn signals is by removing the box that the warning lights sit in, is that true? I have a 2002 Audi A6 2.7 L.

 

I just got the problem, but the mechanic fixed it in about a minute. He did something with the emergency light switch and everything worked great. So, I still say its bullshit, and a way for dealers to ream you...............
