I just picked up my new M340i at the Performance Center last week. I can't say enough good things about the experience. Overall the car is great, it drives really nicely and looks good, too.

What I cannot stand is the auto dimming rear view mirror. There's about a 1/4" gap where it doesn't dim all the way around the mirror and the overall size of the mirror is too small to put that strip out of view. It's super distracting when headlights behind you go in and out of that strip, going from bright to dim.

I'm not sure if I'll go so far as saying it's a safety issue but as I said before it's very distracting and disappointing from BMW on a car this expensive.

I wonder if there's another mirror that could be fitted to solve the problem? Or if an industrious person could come up with a laser or die cut piece of tint that would fill that area. Either way I do plan to see if I can register this concern with BMW.

Then we honestly don't know what to tell you, return the car, take the loss, and get a Honda.

I'm assuming you have sensors, blind spot detection, and other safety features and your complaining about the rear view mirror in an otherwise amazing car. Think like a human Swiss Army knife when you drive you have other tools at your disposal.

I know what you mean, it does look tacky but it's not the end of the world..

And beside, who else is going to notice that..

[golferboy2312]

I hate the way it looks too, but the operation of the mirror has not bothered me so far.

Totally agree. It's annoying when the cars go in and out of that strip where it's not dimmed. I'd love to know the reason behind this since my Lexus fully dimmed. May be a European requirement which they kept the same on all versions of the car.

I find it weird that both mirrors do this and how the passenger mirror doesn't dim. This is especially considering my previous F30 dimmed the entire glass and did it on all 3 mirrors.

But my F30 had a thick bezel around the edges so maybe it's some limitation with the frameless design?

I am confused. To me a rear view mirror is the one inside the car and the ones outside are side views. Yet some of the responses relate to the side view mirrors.

OP: which are you talking about?

I think they all have the same bezel and same auto dimming feature so it's irrelevant whether it's side mirror or rear view mirror he's talking about (although I do think the OP was referring to the rear view mirror).

I was wondering the same thing. It's not the end of the world but is kind of annoying. I'm sure there is a reason why the dimming doesn't go to the edge of the glass on any of the mirrors.

[VipinLJ]

Let’s call them IRVMs (Inside rear view mirrors) and ORVMs (Outside rear view mirrors) for simplicity’s sake. Hehe

And yes. Idk why but that gap seems noticeable in the BMWs. Audi has a very similar shape for its IRVM but the gap was not as noticeable, even though it was present. Same for ORVMs. Plus it sucks that the passenger side ORVM doesn’t auto-dim in the new bimmers. I wish it did.

By gap. I mean the edges on the mirrors that doesn’t dim.

Thank you, I thought that would be self-explanatory..

It's harder to get a proper pic or the inside mirror, demonstrating the boarder in question..

[shawntech]

Agree, side mirror ugly too

Piss off. You obviously didn't read my post. And no, I do not have blind spot detection on my car.

It hasn't bothered me in the side mirror. The rearview, as noted, is particularly annoying and distracting. Typically you'd have more cars behind you than alongside you so that mirror sees more action, even so when cars were in the side mirror it wasn't an issue.

It's like that with both.... pretty obvious if you own the car you can tell.

I feel your anger. That is new "trend" it seems as I have the same thing with my 2018 Audi S4. The outside and rear view have the same "edge". I'm seeing that on more and more vehicles lately.

I have no idea why that was done, because it is NOT an improvement.

I have noticed it on the side mirrors but never noticed it on the inside rear view mirror.

It would be better if it went all the way to the edge but it doesn't bother me.

Yeah they definitely didn't implement this as an improvement. My guess is it's cheaper than going edge to edge, and/or allows them to more easily fit other circuitry in the same envelope.

Having had an E39 with auto dimming mirrors, after time the dimming stopped working because water penetrated the gap between glass and backing. No repair so had to change and they were pricey. Common fault.

On E91 and G30 they were as on G20. I suspect the sealing is better though unsightly but brings longevity.

You can see the same thing when leaving a calculator outside!

Yeah, I had a 2006 Z4, I had to replace the auto dimming rearview mirror inside the car because it failed, that was expensive (seems like it was $600-$800). The sideview mirror on the drivers side did the same thing....so maybe this new design, while I agree it looks crappy, is in response to their mirrors not being reliable.

For what it's worth, I only noticed the sideview mirrors on my m340 looked bad, it was only after seeing this thread that I noticed the rearview mirror had the same design.

[mathys]

That looks awful indeed. Perhaps a sticker to cover up the outer strip would help?

Ridiculous though that it has be solved this way.

[phillyd2]

I too have noticed it but that's as far as my thought process went.
