It is possible to update 2 zone AC to 3 zone adding rear panel ? Looking on wiring diagrams looks not so complex, also some retrofit harnesses and mats are available on aliexpress.

Don't you also need to retrofit the 3-zone temperature flap? Seat heating is a simple job.

That I will try to investigate during weekend, some parts list need to be compared. First I need to find VIN number with this feature :)

How many you need?

Just one with this feature. If you already have that nice, if not I will looked in selling advertisement :)Then I run ETKA for comparison. My Oct is from 2024y with 2 zones. I think there is chance without big work.

Unfortunately It will be too big work, reconfiguration of unit 20 ☹️, no sense to proceed forward...

I know...
