Turn signals not resetting

So 9 days ago I replaced the control module for the turn signals due to them not resetting. This gave me an opportunity to provide a nice DIY where we promptly argued the merits of trying to blow your face off with the air bag.

After reassembling I took it out for a drive to confirm all was right with my work and the signals were repaired.

A whooping 9 days later and they are both broken again :evil: :x

The original lasted 14ish years so I was a bit miffed that the replacement only lasted 4ish, but I chalked it up to crappy new plastics. But 9 fucking days!?!? WTF!

As it is usually only one side that breaks, but both broke on the last one and the new one coupled with the ridiculously short lifespan for the new one, I suspect there is more than mere bad luck and coincidence at work here. Anyone know what else I should look into before dropping another two fiddy only for it to break again?

Are you sh!tting me! I have no response to your question, but cannot believe it failed already. So the new is broken same as the one you took out?

Sometimes you just get a bad part. I just had 2 bad AC compressors in a row on my A8L. First new compressor had the coupler break 2 days after install. Second one (supposedly the best quality model) had a low side fitting hole that was simply about 1 mm too small. Since I source my own parts, I got to pay to swap compressors basically 2 1/2 times.
On the 928, when I recently swapped brake pads, I came to the conclusion that one brake pad slot on one caliper is simply smaller than it should be. I would exchange the part (it's got to still be under warranty, right?) and see if that doesn't resolve the problem.

Yeah I know bad parts just happen sometimes. It's that the issue is presenting for both signals rather than just one side which is the most common complaint.

I'll definitely be reaching out to Suncoast who will hopefully not make me pay another $245, but I'm looking for anything else to check on (like the part that actually trips the reset arm). I don't know the details of how the mechanism works so I'm hoping someone here knows details and what good vs bad looks like.

I'd look at the cancelling lever that's inside of the stalk center that rides the column......Maybe the arm inside of the stalk broke off. Generally speaking the cancelling lever wont extend until the turn signal is flipped left or right, and there is a small tooth that flips it in to push the turn signal stalk back to center, during the turn back to the opposite direction to center. Its confusing to describe. If you still have your old stalk, try and engage the signal and look for the cancelling arm to pop out in the center of the assembly.... it should edge out at a slight angle and if you run your finger against it and push the lever it should reset the stalk to center. If the arm isn't there something may be shearing it off on the steering column. This is how most mechanical cancelling stalks work. That said we're talking about the Germans......They could have this thing set up some crazy kind of way with a miniaturized wizard that waves a wand at the thing and makes the turn signal cancel.... :shock:

Went by my Indy today (P!g is burning oil and then a window regulator failed in the BMW). They happen to have a torn down 986 that it looks like they are building a track car from. The steering wheel is out so I was hoping to get some pics to compare mine against, but the control unit was still installed :(

Called Suncoast and I need to take it to a dealer (installed) and let them diagnose the problem to determine if it should be replaced under warranty.

While on the phone with Suncoast I fished the old unit out of the bits box I tossed it in. As Black-out describes, the pin pops out when the stalk is flipped and it returns the stalk to neutral if to press the pin in the correct direction...

Maybe my Indy will let me pull the module off the 986 when I pick up the BMW and get some pics to compare against.

I wouldn't rule out the miniature wizard theory just yet . . .

Good news!

It's good to be on good terms with your Indy even when you DIY. So he let me look at the 986 and the result is I think the only mistake I made was not tightening the control switch clamp tight enough.

If you don't know what you are looking at it's hard to see in my DIY pics, but there is what looks like a off center washer (though I think it's machined) on the steering column which is what appears to be the trip for the turn signal reset.

I suspect that what has happened is that I didn't tighten the module's clamp enough and it worked itself back just enough that the "washer" is passing under the reset switch.

Of course it's in the triple digit heat index until it cools off to 70 degree days at which point it is supposed to rain for a week. I should really get a garage one of these days... :|

So do you need another part or just some adjusting/tightening?
