the turn signals stopped working although the emergency flasher still worked... the flasher relays are all in one unit located in the dash behind the red triangular emergency flasher(both the turn signal relays and the emergency flasher relays are all part of one unit)...ordered a new unit online for about $50.00, takes about 20minutes to replace

turn signals stopped working although the emergency flashers worked fine... replaced the flasher unit
My Emergency Flashers, come on as soon as I start the car... They go off when they feel like they have had enough of tormenting me... lol. When I shut my Headache off I have to reach up an hit the Emergency Flasher button an they turn off... But that isn't a solved problem, because as soon as I start the car again they may come on, an they may not... When they do finally go off, it may be a couple days it may be a week before I get a head ache!!! Meaning the flashers acting up, Some times it may take 2 or 3 days before shutting off again Very odd and aggravating situation... LOL Any Good ideas would be great... Thanks Guys...
Erratic turn signal. replaced signal relay.
Well the turn signal use to flash once or twice and then i never worked again so then i bought a column switch and changed it and it still didn't work and now when i turn on my car it doesn't stay on and when i drive it it does not want change gears it stays in the first one.

Erratic turn signal operation. Gradually got worse to the point that they would rarely work. I removed the hazard switch/relay above the radio. I took the relay unit apart and found there are two relays on the circuit board, the one for the hazards was working fine but relay for the turn signals would turn on and stay stuck on. I sprayed a bit of WD-40 on the movable part of the relay and now the relay/turn signals are working OK again. We'll see how long it lasts.

Flashers stop working after they warm up. Do not flash after a few seconds. On and off working. Ready to replace relay and see.
Audi TT Quattro: Turn signals worked intermittently for a couple of days. Now turn signals do not flash. Flashers work fine.
Upon safety inspection, we noticed both turn signals blinking erratically, in a pattern. 3 rapid blinks then a single blink, 3 rapid blinks then a single and so on.

turn signals very erratic. replaced flasher after a repair from the web proved to be only very temporary. Flasher replacement was the answer. $36.00 well spent
Blinker wouldn't operate properly erratic behavior.replaced the controller.
replaced hazard flasher relay above radio
flashers flash intermitintly
When i hit the turn signal it starts to flash/click and then freezes on. If it the Flasher Relay and is this something i can fix vs going to the dealer
first it would flash fast after a day of that I now get two flashes and it turns off
