For Passenger side the yeti shouldn't have that many options other than heating, power fold and puddle light.

Drivers side can have auto dimming but for some stupid idiotic reason they didn't do this on passenger side.

I had a similar issue on my XF on the drivers side. Indy fixed it but dealer wanted £1800 for replacement mirror. (Auto dimming, power fold, puddle, blind spot, radar)

The Mk5 Octavia (and Mk IV?)* have dynamic repeater lights in the mirror base units. While the shape of the lights themselves looks very similar, I found (on my 2010 yeti at least) the curve of the Yeti base units to be ever so slightly different. So Octavia repeater lights are not (quite) a direct swap into a Yeti mirror base. Moreover, while the Octavia repeater lights are a click fit into the mirror base (making replacing a failed light LED a simple swap, like a bulb swap), the Yeti's lights are permanently bonded into the base. Can't be removed without breaking something? Inexplicably by comparison.

I would therefore recommend experimenting with a minimal cost (possibly damaged?) mirror unit from a scrapper, before moving to the real thing on the car. The Mk I Tiguan units may be a match though? I've not looked so closely at those?

Let us know how it works out? (Perhaps start a fresh thread for that though? For ease of look-up and referencing in the "How To" section? )

* or do I mean Mk IV and Mk III? Lost track of how many incarnations of the modern, Golf-based Octavia we are up to now?

Mk2 Octavia was on the Yeti Platform. Mk3 and the new Mk4 are both on the new MQB platform.
