I have a 2003 A6. The turn signals come on blink once and stop. Any suggestions?

 

emergency light relay

 

Thanks! Where is it, do I replace it, fix it ...

 

Removing the flasher unit (behind the emergency flasher button), cleaning the contacts with Caig DeOxit , alcohol on a Q-tip, or a ball point pen eraser, and reinstalling. I did this on my wife's A6 about a month ago after having the same problem as you, and it worked fine. However, a week after the fix I decided to purchase a new flasher unit from the Dealers just to be on the safe side. If I remember correctly, the part cost about $40.00. There is a thread here somewhere that explains the removal process, if I find the link, I'll post it. good luck, regards, paul
