I've posted on the maintenance forum, but thought I post here to see if there was more feedback.

R rear tail light failure warning came up. Happens intermittently and resets when the car is turned off. I took it to BMW and they replaced the tail light but that did not resolve the problem.

Has anyone in here had this problem and found a definitive solution? BMW is wanting to hold on to the car now and it could be weeks that they'll have it trying to trace the problem.

Mine is currently doing the same thing. It’s apparently a known issue within the 2 series of the BMW lineup. There’s a guy on here who did a body ground in his and it fix his issues. I’m going to track down that thread and try the same fix on my car. Dealer isn’t fixing the issue, they just reset the fault, and check connections… and send me on my way.

Incidentally, my is the left hand side. But I believe either, or both can have the issue on any given car.

I had the same thing happen to me a few weeks ago, but since then, the issue hasn't shown back up. Actually taking the car in for scheduled maintenance today and will mention it to them. We'll see what they say.

Usually replacing the rear taillight fixes the problem. There are several threads in the OG side of rear taillight intermittent failure.

Mine has been fine since my taillight was replaced.

So.. just took my M2 in for scheduled maintenance and they wrecked my car..

Will start a thread on this later today..

Wtf?!?? Are you serious?

[okla_m2c]

Two wheels trashed. Front bumper messed up. Front lip destroyed..

Really wish I had a dash cam. Dealer says "tech served out of the way to avoid another car and instead hit the curb." I highly, highly doubt that was the case.

So sorry man. Sickening.

[okla_m2c]

They didn't even look at the rear light issue..

[Moflow]

Ugh. That's awful to hear!

The question you need to be asking is “why were they driving it in the first place for just scheduled maintenance?”

I yelled this at my screen as I was reading. I now just wait for my car and track it on my phone lol. Absolutely no need for them to drive it on scheduled maintenance

[okla_m2c]

I told them the exact same thing. There is absolutely no reason why that car needed to come off the lot. They said "it's routine for us to test out everything after we work on cars".

It's all bullshit of course.

My car hasn't exhibited this yet, but I strongly suspect it's corrosion in the connector or housing somewhere causing increased contact resistance which ends up tripping the very sensitive bulb check.

My dealership always unplugs my dashcam too, really annoying especially if something like this happened.

[okla_m2c]

Pics posted on a new thread. Sorry to derail the convo, OP.

This is also my suspicion. The replacement tail light did not fix the problem, so it makes sense that the connector could be to blame.

Please keep us posted on your findings as well. It’s obviously a pretty big problem. I’m surprised BMW hasn’t had to do a major recall yet.

My M2c got to where both rear lights would show the malfunction error at the same time.
I finally got a picture of this on the way for repair, and was lucky enough for the error messages to still be showing when I pulled into the service bay.

Both rear light assemblies were replaced, so far still error free.

How long have they been error free?
