I bought a 2023 SIII last year and soon found that over my previous SII some parts had been scaled down by Skoda. One bit I did not pick up before was the passenger wing mirror WITHOUT the autodimming function I only found out when driving at night once.

According to my dealer both mirrors included autodimming - a little dim on their side.

I tried to buy a OEM retrofit mirror - none on offer from Skoda.

I then found an instruction by Skoda.cz which is ONLY for LHD, i.e. continental European cars. My local Skoda dealer did not find an equivalent.

So I decided to buy a preFL autodimming passenger mirror from a 2017 car without the lane assist (SWA) function. PreFL cars have a SWA icon in the mirror glass, mine has a yellow warning light in the plastic casing.

I was not sure if it might fit into my mirror at all as Skoda seem to be selling different passenger mirror glasses at very different prices according to the kit fitted to the mirror. Also I was a little weary of cracking my mirror glass as the replacement prices for a new one are eye watering.

I tested the autodimming before taking anything apart by putting 12V onto pins 2 and 6 - it worked.

I could practice to remove a mirror glass on the one I bought. It comes out with a little bit of force when moved into the lowest position and levering with a wide plastic spatula from the top. It will also not just drop out as there are still wires attached on the inside for the heating.

The replacement mirror (preFL) with autodimming has 2 more wires attached on the inside and an extra little bracket on the back of the mirror glass to secure this bracket.

The fitting is exactly the same as on the non-autodimming FL one.

After disconnecting the heating wires on the replacement mirror I took the mirror motor and the frame out. This is done by removing 5 little Torx screws, 3 going the the motor casing and 2 extra in the frame connecting it to the painted mirror outer casing.

The black frame needs to be unclipped from the back casing which allows more access to the wiring. The back casing slides off the mirror easily now.

I removed the cloth tape from the preFL wiring to be able to get the autodimming wires out of the loom. The autodimming wires are pinned into the 16 pin connector on pins 2 and 6. In my FL 2023 connector pin 2 and 6 are ........ yes you guessed it - empty. The wires are Black / Green and Black / Grey.

To get the the wires through the mirror bracket that attaches it to the door you have to remove the black polystyrene which is only pushed in. It comes off easily. There is a little bit of grey sealant between the cloth tape and the polystyrene.

To unpin 2 and 6 you have to take the plug apart.

Now it was crunch time for my car. To fit the new old mirror I removed the glass first on mine to check for compatibility. Exactly the same. Now I removed the door trim - one large Torx below the armrest and a 10mm Hex at the bottom which needs to be turned 90°. The pull the trim off the clips. They all survived. Now detach some of the electrical connectors and the door opener. There is also the drainage for the umbrella compartment. I could not get the door trim off completely. 2 connectors were so inaccessible that I gave up, but the door trim DOES NOT HAVE TO BE REMOVED! In retrospect these connectors were from the window controller and this can be lifted out of the door handle.

Once you can get into the door go straight to the door controller at the bottom left. Remove the adhesive protective cloth cover from the connectors and ONLY disconnect the door mirror plug.

I pinned the new wires into the door mirror plug and connected it to the autodimming mirror to check if it working together with the driver side and internal mirrors. It did!!

All the wiring is in the door right up to the controller.

Now unclip the door mirror loom only from the clips in the door. Then remove the trim for the speaker covering the spline XZN screw holding the mirror. I did not remove the mirror completely as I did not cut the loom in the door out. It is very securely taped together. I wrapped this new 2-wire loom in cloth tape and taped it alongside the existing loom going into the mirror.

I did the next steps with my son as one person was holding the mirror and one was working on the mirror.

On my mirror the steps were the same as on the donor mirror.

Loosen the polystyrene on the bracket side. I cut one tiny cable tie which got on the way.

Remove the 5 small Torx scres holding the mirror motor and the black frame.

Unclip the frame.

Remove the back cover.

Now you have access to the wiring channel in the mirror. This channel is quite full as I have SWA, 360° cameras, courtesy light and all the mirror motors as standard. I fed a small wire wire back down to be able to pull the white autodimming connector up into the back of the mirror casing.

Then refit the back cover, screw in the frame and mirror motor, push the polystyrene back and take care to reseal the loom. Screw the XZN screw in to hold the mirror, refit the speaker trim

and make sure to reconnect everything in the door card. Fit your new auto dimming mirror glass.

The new old autodimming glass does not have a VAG PN. It only showed a number string: 19363 LH, 925-1914-001, SK48 LH CVX, 20817 JH. I think this is a Gendan number.

Skoda seems to be selling lots of different mirror glasses at very different and interesting prices. Looking at the PR numbers I thought that some of these functions surely have to have different mirror glasses, but I think you are buying the loom too because only the loom determines the various functionalities.

Looking at the parts I cannot quite understand why Skoda skimped on the AUTODIMMING. It cannot really cost a lot more over the parts used.

I hope the new Superb IV will get a passenger autodimming mirror option.

me too have 2023. Mk.FL, but this "feature" i noticed just few weeks ago

Škoda's Simple Clever transformed to Save cents by add Drawbacks

 

Magnetic Trunk Light Lamp has been gone
i used it just once, but it were useful when had to mount spare wheel quarter past midnight

 

 

Armrest Storage Compartment Lamp has been gone

I have also retrofitted the boot light but I have not written that one up here. The wiring was a right pain.
