Hi 

Is it possible to retrofit auto dimming mirror to car with standard mirror? 

 

Car has rain sensor already and so assume a power source is already there and possibly just a switch over of units with auto dimming feature activated?

 

Reason is I took delivery of new RS car and whilst ordered Auto dimming the car only has folding mirrors but non auto dimming rear mirror :-(

 

I want to check here whilst also asking dealer of possible retrofit. 

 

Thanks

 

Look at this post:

You'll need to buy some stuff (mirror, proper connectors,...) and do some wiring, but not that hard if you're a bit of "technical" guy. Follow my guide on a link that @Gromle already posted.

thanks for confirming .

As was spec'd on car order and not delivered I am going to try get the dealer to do it! 

 

At least now know it is possible.

See attached picture of my new car mirror.

 

Has the design changed for auto dimming mirrors as this is different to my previous RS MY15 auto dimming mirror which had button on/off on bottom and sensors to front and rear?.

 

Can anyone confirm this is the new auto dimming mirror. Only have the car 2 days and so not got chance to check at night but did place hand on rear sensor to check if mirror dimmed but no luck. If this is not the auto dimming mirror then what is this rear sensor?

 

Thanks 

 

Personally I would do the opposite, replace my auto-dim with a manual dim. The auto-dim gets it wrong so often and there is no manual override

Yuh it's not very effective - I had one on my previous octy only because it came as standard on the model/spec I chose (mk2 SE+) - but I would rather have a manual dimmer and the cash back.

But that's it I was able to turn previous one on off by button but I found it work well.

 

Question is if I actually have auto dimming with new car or is this the standard mirror with some sensor on rear for something else?

Perhaps they are using the same casing for the standard and auto dim mirror to save some costs?

 

There would also be a sensor on the front of the mirror if it is the auto one.

 

The rear (forward facing) sensor detects if it's dark or not and the front (rear facing) sensor detects light behind you.

 

I was very surprised to learn that my Saab already had the connector for an auto dimming mirror so I bought one off ebay for £20 and fitted it within 5 mins! Obviously not like VAG who don't included 1mm of extra wiring or connectors for things not fitted to the car originally!

You can turn off the auto-dim function (I think) but no manual flick up/down lever. The lever system worked fine

Could that sensor be for high beam assist?

You can remove the upper part of plastic cover behind the mirror (the one that connects mirror holder with headlining). You will see if you have two connectors beneath, one is for rain-light sensor and other is for the mirror. If it's only one, then it's for rain-light sensor and mirror is just dummy...

The auto mirror has light sensors front and aft, to compare the light from the front of the car with that coming from behind. The sensors at the front are too low down & do not 'see' bright headlights close behind.

Hi,

 

Can this be done also in the new Skoda Octavia 4 2020?

BCM Pin would be the same?

Inner light cabel connections can be done?

 

I did this on my MK3 facelift and works.

Unlikely to be the same pinout, you need to get a wiring diagram from erwin to check.
