This. I had the same issue turns out the ground was kinda crusty looking. Still under warranty so they replaced the right tail light. I guess that one looked the worst. They only replaced the board tho and re-used the other parts.

Kinda disappointed I was hoping I would get a whole new set of tail lights.

Got word they replaced both tail lights on mine. I'll know for sure if it's new assemblies entirely when they drop the car off tomorrow morning. Interesting though they are doing bare minimal replacements on some and completely replacing both sides for others

Then it would go for weeks working perfectly fine...

Took mine into dealers to see if they would cover the cost(out of warranty) as it's a known SIB. They wanted £120 to run a diagnostic check first. I said 'I've told you what the problem is and the fix' . No sir. So I drove it straight home again to fix myself , now if I could only find that post with the fix for the ground wiring , I've also sourced the bulb holder with the 8 pin socket. £30.

Wow that's insane... they covered mine under warranty 100% and I had them do it in conjunction with the service. They replaced both sockets and wires and bulbs as an entire assembly.

I know this is an old thread but it just happened to me.

First the turn signal says its no good, then it's fine, then its no good again. Then the brake lamp, and finally the reverse lamp.

Basically every lamp in the housing.

No water, no cracks, and it's just the fried harness. Fixed under warranty, and I made sure they replaced the wiring.

Just bought a used 2016 M235i Vert. Having the same issue. Started off very randomly, now becoming more and more frequent.

Anyone have the part numbers for these lights?

I don't think I'm under warranty. I just bought the car and had it shipped to me.
Thank you,

I was hoping it was just a one time fluke thing but after multiple shut downs and restarts it's still the same issue. I even tried it the next day and same problem.

There is a known fault, I'm told up until late '16 or early '17 - inadequate ground wire that eventually burns out/melts. Multiple solutions - initially they soldered in a second ground wire harness to your original housing, then they started replacing the units with the newer, better units. If you have this done, take a good look to be sure they don't botch the install - they did on mine, pulled the weather-stripping gasket back so the upper/inner corner was obviously loose and left a 3mm hole for water to get in. They also seem to 'forget' to offer both at once, so I've made 3 trips now to finally get it all updated. The water-entry is a separate known fault/issue, but probably throw's similar codes once things start shorting out.

There is a post here about the factory 'fix' (adding the wiring harness), but try to pressure the dealership to give you two new housings, especially if you are under warranty. If you have to DIY, it is a fairly simple thing, you won't really need a new housing or harness. Info is here: https://www.newtis.info/tisv2/a/en/f...ess/1VnZ8zZX2B

New to the forum. Any ideas guys? My 2 series RH side rear light cluster has gone on the blink today. Removed it and it looks like one of the 8 sections of the lighting plug has melted and the matching pin on the cluster itself is blackened. I had problems with moisture when it was new, so the dealer has looked at the lights before. LH side was replaced and still looks as good as new. It looks to be like the dealer have retro fitted some sort of extra cable on both sides, as it has a date tag of 2017. But the RH has still malfunctioned. Anyone know if it is definitely covered under an extended warranty? Mine is 11 months out of UK standard 3yrs. Thanks.

Who's ideas was it to put the fuse panel in trunk? The trunk can leak and fubar a bunch of electronix. I rented a small MB in Germany years ago. The fuse panel was in the passenger side floor!!! Gott im Himmel!

Does anyone know if this is covered under CPO?

I am getting the taillight errors. Today the brake light didn't work but the turn signal did. Yesterday was the opposite.

I jiggled around the wires and I would get different effects of light bulb failures. Finally jiggled them in a way that all the bulbs came on, but don't see that lasting.

So I've got this now, too. Looks just like johnnie228's photos - melted plastic, burned pin.

Has anyone tried using wichitagreg's extended warranty post as leverage for dealer replacement?

[p912guy]

So this obviously appears to be a common fault. I'm at 53K miles and I just had the Right Turn Signal Error appear. Guessing it's the same as everyone else - ground wire issue. Guess I'll need to get it to the dealer and see what they say. Hopefully since I'm still under 48 months by over on mileage, I'll get some type of dealer assistance on this "known issue". We'll let you know what happens.

This multiple bulb malfunciton just started on my CPO 2016 M235i. I'm curious to see if it's covered. I'll call the dealer on Monday.

[alxsaleen05]

does any one knows how to installed repair kit for the rear tail light on M235i?
