Audi Repair: audi tt blinkers clicking noise, beam light, signal relay

Question
Awhile ago, when I used my blinkers, the clicking noise associated with the blinker continued even though the blinker was out (turn complete).  Now the clicking noise happens almost incessantly, even when I first start the car.  The lights aren't blinking, it just sounds like the blinker noise.  Any thoughts?  Its starting to drive me crazy!

Answer
hello
in 99% this is caused by turn signal relay, The relay is inside 4-way flasher switch above the radio, so the switch itself need to be replace . Few times after replacing the switch (on A4 and A6) the clicking stayed sometimes after making the turn , this was caused by loose conntacs inside steering wheel/hi beam light switch.
So , start witch 4-way flasher switch.
good luck         Greg
