As I had a spare autodimming / anti dazzle mirror from our Superb, I thought I might fit it in my daughter's Fabia pre FL.

 

There are two types of autodimming mirrors which will fit - one with a small foot like the original Fabia mirror and the one for a RLS bracket. Mine was for the later.

Parts needed:

 

1K0857511E - Autodimming mirror

3AA845543B - RLS windscreen bracket

4B0971833 - 6-pin connector

000979009 - Female crimp / terminal connectors to wire everyting into the 6-pin connector

And wires

 

Polyurethane windscreen adhesive - I used Autostar Germany PU 9000 Ultimate Windscreen Sealant 310ml.

 

The pin outs for the 6-pin connector are:

T6ay  -Autodimming mirror
/1 - ro/ge - to switched Fuse (ignition +15)
/2 - Br - earth connection

/3 - sw/bl - Reverse gear output,  J519, XP1 T6o/2 (black)
/4 - Wing mirror, not in use
/5 - Wing mirror, not in use
/6 - br/ro - front interior rooflight  - I soldered a wire between the switch and bulb.

 

Before you start check that the new mirror works. Connect it to 12v and earth and check the green light comes on.

To remove the old mirror hold onto the foot and twist it. The RLS bracket and mirror will fit over the existing bracket. So you do not need to remove the old one.

I prepared a loom from the mirror to the fuse box and J 519 above the driver's foot well and taped it with wire tape. I took it round the driver side A-pillar. To remove the trim simply pull the trim off. There are 3 metal clips holding it. They like to slip out. At the bottom you need to unclip the speaker connector.

 

Pin 1 I soldered onto the cigarette lighter. I moved my cigarette lighter onto a switched 12V+.

Pin 2 goes onto another earth. You can use the interior light, but ours was very short and I did not want to solder up there and wired it behind the dashboard.

Pin 3 goes to the BCM (J519), XP1, Pin2 (T6o/2)

Pin 6 as above to the roof light. This is a 12V+ into the mirror when the light is on.

 

Once the wire is in, glue the bracket to the windscreen. Clean and degrease the glass well. The description says it has cured within 1 hour but mine was still soft and I left it over night. The new mirroe simply slides on. If it is a little stiff, use some oil on the mirror springy clamp.

I did not use a harness cover – 1K0 857 593A, 1K0 857 594. I used shrink tubing instead.

 

Connect the wire and put the trim onto the mirror.

 

Time needed about 4 -5 hours.

 

 

no piccys ???

 

Interested to see what it looks like V the Gentex I ftted to mine which was only a 2 wire install.

The first 2 pictures are the mirror fitted, the third at night with the little green LED on.

 

 

 

 

Here are the PNs. I did not use the yellow repair wire but made my own wiring.

Cool very similar, apart from the face is grey.

 

Heres the one I fitted...

Hi 26DIPP.

 I was thinking of using just two wires. My car mirror has the same fitting as the replacement mirror. I have everything else such as auto lights and rain sensors.  So only need the wiring for auto dimming.

 The Mirror should turn up today so I'll take it into work tomorrow and work out what colours i need to work the auto dim work.

I wonder if you can help?

 

I have a secondhand mirror ready to go in but only have 4 wires, they are:

 

Brown/red

Brown

Black/blue

Red/orange

 

im guessing brown is earth but I cannot work out the abbreviations you have used so I can find the power.

ro= red

ge= yellow

sw= black

bl=blue

br=brown

They're from the German words Rot, Gelb, Schwartz, Blau and Braun.

Thank you very much

@26DIPP at the start of your post you mentioned two options, one being the small foot option from the fabia... could you possibly provide any information for that particular part?

I am currently trying to source parts for the same project and really struggling to find either a mirror which has autodim and is the twist on stem, or the style of mirror plus the mount from the skoda superb/octavia. i just miss my autodim and the mirror in my caddy is absolute poop because switching the switch moves the mirror so much all i can see is my rear seats. thank in advance.

Hi,

This one is pretty similar to what I used.

https://www.ebay.co.uk/itm/135709654756?_skw=skoda+autodimming+mirror&itmmeta=01M7DMZXN61REXT0AH6R7YJYKB&hash=item1f98ecfee4:g:znYAAeSwKc9oAQnn&itmprp=enc%3AAQALAAAA0CHNgUiiE%2FjQhlDTaMiAde%2F%2BScYTeFLpcKeZnqF5dZO0ylDeF3GRHZdHMdn8SqTeEO8hd%2BpRQ2%2FH1t72tPfLx%2Fc0ducyTE70z2w2PmhTBauWmldtyuJIWog9BCRgw9SFeWoqJaW0y8TqVIj178qJZFCbKUKhtTCl7%2BCytucDeiL7lAoycn95mPDUQ04E8yrtRvxpId4AfLjUhtYEvLse7mNfqd7qUgLlZSCmfAo3UYcjMDewVgh9qtxG4rszDdixwwk5HfwmyOITsqKO895nr4U%3D%7Ctkp%3ABk9SR-Lb_7S7aA

It does have the wiring connection included.

The Fabia mirror / windscreen is a different design from the Superb. The FII uses a small foot / mount which is also integral to the windscreen whereas the SII and other cars use a larger bracket - 3AA845543B. The larger bracket fits around the small FII one and I hid it with the screen adhesive. You will get it from a dealer.

Thank You for the reply and the link, and Your original post, very helpful! The mirror in the link is the same mirror I have sourced, I was left with the ceramic circle after removing the factory mirror so I have mounted just below as I managed to get a working sensor to mount in the middle of the retaining bracket. All working fine, Thanks again
