C5 S6 Low Blinker Fluid?

[Fast Co]

No that would probably trigger the auto check, right? My turn signals (either direction) will blink for a few cycles then stop even though the stalk is still in the "turn" position. This is not the 'convenience' feature, just normal turn signal. I tested the hazard (pushed the triangle button on the dash, not bench test) and they seem to work fine. All bulbs appear to be functioning. Is there a separate control module for turn signals?

The hazard button on the dash is the relay for the turn signals. Mine was acting the same way until I replaced the hazard switch and all is well now.

Sometimes it would get stuck (blinker would stay lit) or it would blink once or twice and then nothing.

Are you getting the lights to turn on regardless of the signal stalk? I was having a consistent click from my hazard relay and I replaced the signal stalk. All gone. I got mine from ECS and about an hour later it was all done. Just make sure you have the triple square for the steering wheel otherwise you'll get stuck.

In my experience lights starting and then stuck on tends to be the hazard switch with the relays as already mentioned. Very common audi failure.

The stalks do go bad as well, however the examples I've seen include not coming on at all, etc.

Good luck.

Although the 4 way flashers seem to work fine, I suspect it is the switch/relay. I tried holding the stalk as if in passing mode, also flicking it off then back on. Sometimes it would click a couple of cycles and stop other times it would not activate at all. So I ordered a new switch, if that doesn't fix it, must be the stalk. Thanks for the suggestions. I will post results.

I believe that there are 2 relays in the hazard, one for hazard one for turn.

I had a similar issue with my turn signals and it turned out to be the turn signal mechanism on the stalk. As mentioned the emergency flashers contain two relays and even after replacing the emergency flasher switch I still had the issue which was a clicking coming from the dash that sounded like the relays were short circuiting. The noise would get particularly annoying just after using the turn signals and no matter what I did the sound would not stop. I replaced the turn signal switch on the stalk and that solved the issue.
If that doesn't fix it then it might be low blinker fluid. I believe that Amazon has some great prices on blinker fluid and there's a helpful DIY video on You Tube that explains how to change your blinker fluid.

My symptoms were that when actuated, the turn signal would flash (and click) a couple of times then go silent with no blinking light even though the stalk was in the signaling position. Different from the scenario above. I ordered a replacement part but since it hasn't come in yet and I am driving to Cleveland (and back to Pgh) tomorrow I figured I'd swap the hazard switch from the black RS6A. A brief test in the garage - so far so good. Turn signals work properly. Hopefully that does the trick. When the new switch arrives I will install it in the RS6A.

Thanks for the suggestions. Next project... adjust the "johnson rod" maybe there's a video for that too ;>).

I drove the S6 ~300 miles today, problem solved. Glad I switched the switches. The weather was crappy, intermittent heavy showers, some standing water on the turnpike... couldn't ask for a better car to make the trip.

Not that it matters now but I have a post in here from a couple of years ago detailing how you can replace the $5 relay inside the switch in around 10 min. You'd have to search, as the mods didn't reply to my request to sticky it when I wrote it.

Edit: linky.

Are the stars in some certain alignment right now? My black '01 Allroad just started this last night. Going to try swapping the flasher switch from my A6 donor (that I am swapping the 01E from) and see if the problem rectifies itself. If so, then I will get the Omron relay sparkstack recommends in the write up linked above and fix the malfunctioning one so I have a backup. This was fortuitous I logged in today.

OK, this is weird. I switched the switches in the Atlas Grey S6, figuring I'd put the new switch in the RS. But I had to move the RS before I had a chance, so I installed the old switch from the grey car into the black car so that I could at least get a corner lamp to flash if necessary. As I pulled out onto the road I flipped the stalk and the turn signal worked fine. I drove around the neighborhood expecting it to cease working but it seems ok. This is the same (faulty) switch that was pulled from the grey car. So all I did was swap the switches between the cars and they both work now. Of course I did purchase a new switch, maybe it was the placebo effect? I suppose that if I return the new switch one or both of the old ones will crap out.

[Sparkstack]

I wrote in my guide that giving the switch trim a good knock would get the turn signals to work again for a while. Presumably removing and replacing also has the same effect - it frees up whatever in the relay is causing the contacts to bind. Let's see how long yours keeps working for.

[Fast Co]

I agree with your theory. Now that they're both working I'm going to leave well enough alone. I'll keep the new switch, it's only a matter of time. Now that I see you're parting out your S6, I should have thought to ask you first. How do you like the S8?
