How do you replace Audi tt turn signal relay switch?

the relay is behind the hazard light button in the center of the dash. you can hear the clicks of both the hazard lights and the signal lights coming out of that area.

to change out the relay, take out the radio, and you should have a pretty easy access to the relay switch right above the radio unit.

if you need precise instructions on how to remove the radio, do a quick research and you should find the answer. if you've already replaced the radio with an aftermarket unit, this should be a lot easier.
