Extremely annoying non-dimming border around auto-dimming interior rear view mirror

Hi Everyone,

This is my first post on here as I just bought my first VW, a 2019 Golf Sportwagen SE. I upgraded from a pretty bare-bones car (a 2011 Mazda 3), so just discovering all the bells and whistles in this vehicle, some good and some bad. One of these bells and whistles I absolutely hate : The auto-dimming interior rear view mirror.

The auto-dimming feature is working properly I believe, but they just designed this thing such that there is about a 1/2-in border along the edge of the mirror which does not dim. This may sound like an innocuous issue, but I have some light sensitivity issues and what is happening at night time is this border is causing a strobe light effect to my eye. The headlights of the vehicles behind me go in and out of this non-dimmed border going from super bright to dim, and like I said it's a strobe effect and very distracting and unpleasant to me. I tried to capture some photos of this below with arrows pointing to the non-dimming border as best I could:

What is frustrating is that I was perfectly content with my old vehicle's ordinary manual dimming rear view mirror, the kind with the little tab on the bottom that you simply flip open at night time dimming the entire mirror. Having this fancy high tech auto-dimming mirror seems to be the crux of the problem.

So what is the solution? I thought of two ideas so far:
  1. I would be perfectly content going back to the ordinary manual style dimming mirror if there is one compatible with this car. Perhaps the base model Golf mirror has the manual style dimming mirror and the one is compatible with my Sportwagen SE? I'm not sure if going this route would impact some other systems like the windhsield rain sensor or anything else on my model / trim?
  2. Purchase some glass tinting film or tape and try to carefully cut it to a shape that fits just that the exact non-dimming border of the mirror, not the main tinting portion. This sound pretty tedious to cut it to just the right shape, line it up perfectly and not look sloppy, and I'm not sure if that border serves some functional purpose which I would be disrupting by covering it up. This would also result in the reverse problem: a weird permanent darkened border around the mirror during the daylight hours, but that is the lesser of two evils to me.

Any thoughts, ideas, or input here is welcome. I'm sure someone else owning this vehicle has encountered this same problem and is as bothered by it as myself.

Thanks in advance!

You could always switch to the autodimming model that has the frame. It just doesn't have the homelink or the compass in the mirror.

One of these frameless auto-dimming ones should fit? Check with supplier:

My mirror does not have homelink buttons or compass. It is the plain mirror with auto-dimming only.

Also, the problem is not in the mirror frame or lack of frame. If you look at the arrows I drew in the images I posted above, the problem is in the mirror itself within the frame: there is a 1/2-in boundary within the mirror itself which does not dim. This is clearly by design but it's extremely annoying to me. Any other auto dimming mirror option is going to have this same design flaw, no doubt.

It's smaller on the frameless one, but the non-dimming outer edge is definitely there.

That's why I mentioned getting the autodimming mirror that has the frame. The frame covers the outer edges that you're complaining about. Basically a black plastic frame instead of the reflective mirror "frame" that you have currently.

Yeah, I understand. I upgraded to the frameless style and never noticed, but it probably has a 1/4" edge that doesn't dim. It looks a lot better than your stock mirror IMO. The HomeLink and Compass are built into the mirror so they would be bonus features. Win-win.
Make sure you confirm which model works - there are a few versions.

The GTI S came with a regular (non-dimming) mirror with the flip up tab. you can get one of those, and sell your current mirror for a bit of profit. Or maybe see if someone on the forum would trade their standard non-dimming mirror for yours.

You can also try putting some black tape over the edges of the mirror to cover up the non-dimming portion until you decide what to do.

Good info guys. I guess I can see why they thought replacing the plastic frame with a mirror-like frame would be considered an "improvement" as it would increase the total size of the reflective surface area. But, the fact that extra area now does not dim is a huge negative to me.

Ok, so...

Plan A I'm going to try some tinted tape over the edges and see if the auto-dimming continues to function properly. Hopefully that works and doesn't look too sloppy.

Plan B If that doesn't work I'm going to ask the dealer if downgrading to a non-dimming mirror with flip-up tab is compatible with my vehicle or not (mine has the rain sensors, blind spot detection, lane assist etc. and not sure if any of those are is baked into the mirror itself).

Plan C Ask the dealer if downgrading to the previous version of the mirror, with the thick plastic frame, is compatible with my vehicle.

I can't make any promises. But when I had my MK7 GTI, it had the basic 'dumb' mirror, which I upgraded to the frameless, auto-dimming mirror. Let me dig through my box of stuff, and see if I have my original mirror still, since I didn't swap it back in when I traded in that GTI. I don't remember if it just got tossed in the trash or not. If I have it, you can have it free of charge. I'm nearly positive it would mount to the windshield fine, the question is about the trim. There might be some slight gaps, but it's easy enough to swap over and see if it works.

Dug through my boxes of discarded spare parts, don't have the mirror any longer. Sorry :(

Should work. The main sensor is actually on the front side of the mirror, facing oncoming traffic.
