Auto dim to manual rearview mirror swap

[Rog_B]

Yes I know, everyone loves auto dim... except me.
I have seen manual interior mirrors for sale. Does anyone know if it is a straightforward swap? I don't have high beam assist according to my option codes.Thanks

Should be, remove the trim around the mirror, unplug the connector from the top of the mount, remove mirror and replace with a manual one.
Search for fitting auto dip interior mirror and it’ll show how to remove the trims and mirrors.

Many thanks and hoping you're having a peaceful Christmas!
I was wondering about the connector being unplugged throwing up a fault?
The back of my mirror has a little window, I thought might be an ambient light sensor. This isn't on the manual ones I've seen.

I don’t think it’ll throw a fault as it’s wired to the fuse box, I think the sensor is used to monitor ambient light. I’ve removed my manual mirror and fitted an auto one, not got around to wiring it yet, it’s been months since I switched them but don’t use it much at night so haven’t felt the need, it just looks so much more modern.
Removing the manual mirror for the screen was the worst part, it needed a lot of force to rotate it off the screen mount, but once off the new one fitted a lot easier.

Audi A3 S3 auto dimming mirror retrofit

I wanted to write this up because I really had gather bits and pieces of many sources in order to figure this. Some of your 2015 guys didnt get the auto dimming rear view mirror from the factory. This what you need to get it done. you need mirror part # 8V0857511B which I found on US...

Yes I tested it with a torch, it's an rear ambient light sensor so the dim function is off above a certain level.
I'll have to double check the mounting so I order the right fitting.
Thanks for all the help.

Any chance you could please tell me the part number of the your manual mirror?

 

[stubbly46]

Yes of course but I won’t be home until late on the 28th and I’ll take a couple of pics for you too

Thanks that's very kind. I found one on the Bay for under 20 quid. The numbers are very slightly different but the fitting looks exactly the same. If not it can be returned. I'll update when it arrives

Sadly although the new mirror fits and works great, the actual construction is slightly different and I can't the rear trim piece on... grrr.
Even the one supplied with the mirror doesn't fit. I suspect it's an 8P mirror as it looks like my old one in my previous car. So it's going back...
Do you fancy selling me yours by any chance?
Cheers Rog

Hi Rog, as my mirror isn’t wired up and functioning at the moment I’d rather not sell it until I’m up and running.
Hope you understand

Sure completely understand. I'll find one with the same part number

After one mirror arrived and turned out to be another auto dim, I finally got the right one, same as pictured above by stubbly46 from SCB breakers and it is absolutely perfect! At last no more SUVs frying my eyeballs night and day
Getting the rear tints done next week so that will help too.
