Octavia Mk3 (5E) Facelift Heated Seats Retrofit – What Parts Am I Missing?

Hi everyone,

I'm planning to retrofit heated seats into my Škoda Octavia Mk3 (5E) and would appreciate some advice from people who have already completed this retrofit.

So far, I have purchased the following parts:

- 5E0 820 047 N – Climatronic control panel.

- KUFATEC 43340 – Heated seat retrofit wiring harness.

I'm planning to install a different set of seats with factory heating elements.

Before starting the installation, I'd like to make sure I have everything I need.

Could anyone who has done this retrofit let me know:

1. What additional wiring, connectors or adapters might be required?

2. Do I need any additional wiring between the seats, BCM and fuse box?

3. Is my existing BCM compatible, or might it need to be replaced?

4. Does the retrofit require any additional modules or relays?

5. Is any coding or adaptation required using VCDS or OBDeleven?

6. Is the KUFATEC 43340 kit sufficient, or are there other parts I should purchase?

I'd really like to get everything working as close to OEM as possible, including control through the Climatronic panel.

Any advice, part numbers, wiring diagrams or links to previous retrofit guides would be greatly appreciated.

Thanks in advance for your help!
