I think this must be a relatively common problem. About 5 months ago i had a notification stating (turn indicator rear right failure) where the indicators would flash rapidly when activated. Took it into dealership. The fault didn't repeat for them of course and the fault code hadn't stored, so i was sent on my merry way. A couple of months down the line it happened again. I made sure to take pictures/video this time. Also had an ABS failure, rear diff failure and stability control failure. Fortunately this was just from a faulty front ABS/wheel sensor which got replaced under warranty. This time they replaced the whole right rear cluster and the problem was resolved. Anyway, the left one has failed now. Fun stuff. Have any other people had one or both rear indicator units fail? Guess it doesn't help the stereotype.

Mine has happened once ever where I went to signal to turn right and it blinked rapidly, but then I switched the turn signal off and then went to signal again and it went back to normal. Has not reoccurred since.

Oh I forgot, mine was affected by the tail light recall as well. My rear right taillight housing was cracked, so they replaced it. Rapid blinking was on the old one, new tail light has not had any issues.

It's a typical issue with the LCI taillights, my solution:

Yep. Rear left went crazy but I didn't notify the dealer. Last time I went for service they told me the tail lights were recalled and apparently replaced them. A couple of weeks later I had the malfunction on the rear left again. Couldn't tell if they actually replaced the lights.

Wonder why Bmw hasn't issued a SIB for this.

No idea... Maybe they're just sweeping it under the rug because it only occurs intermittently and the model is almost on its way out :

This has been an issue since the E46 days, I believe it's a combination of weak ground and a CANBUS bulb set up triggering an error this error.

Yeah this issue has plagued Merc for a while too. On my ML I too had to retrofit a new ground wire that came as part of a kit. But you are right, why fix it if only another year left.

They have. My dealer used it to fix my wiring harness. I haven’t had a problem since. Also a common problem on three series.

Wonder if this problem was fixed in the '19 and '20 M2C?

Thanks for the responses. Guess the permanent DIY fix is the only way forward then as it'll eventually become an out of warranty issue. Disappointing that they haven revised the part if that's the case. Mine was an early production M2C. Has a revised light cluster/ wiring loom not been released? I think I'll still book it in to get the left done then retro the fix onto that if needed. Its annoying and people must think 'wtf' if they're following you and your indicators are doing different flash patterns.

My 12/18 Production had the rear left turn signal failure light flash the other night, first time it ever happened. Works fine still though.

If you have a MY19 this is your chance to get tinted taillights free.

That's not how BMW gets down..

They're not going to replace it with the 'tinted' taillights, they're going to swap it with the same exact style that came with the vehicle. The part numbers differ between both versions..

Trust me, I know from experience..

Got you

Just be careful because some people might take it to heart... After all, this is the internet, so you know, everything you read is true..

Yeah, honestly don't care how they take it. If someone misinterprets or gets bent out of shape that's their problem.

I just got mine replaced yesterday. Rear Left indicator.

Now I just have to sort out the aftermath of them chipping my rear bumper.

I had the dealer swap my M3 silver glowing badges for the update black ones, different part number. Just asked nicely as price was the same and they got it approved via BMW.

That's really cool of them to do but not something that's typically done.

To a manufacture or insurance company, they classify that as "betterment" of parts, which can be construed as soft fraud, on their part.

A warranty or insurance is suppose to put you in the same exact position as your were, prior to the loss or fault. But I guess as courtesy, they did you a solid.

So the 2020 cars with the revised taillights did not fix this issue?
