Seat Ibiza rear parking sensors

[Sketch]

Hi!
I am looking to fit rear parking sensors to my 2020 Tsi Fr 115 and I am unsure which parts I need. I couldn't find any great information in this, but apologies if I have missed a post.

The parts needed are (as far as i know):
- Wiring from car to Control Unit
- Control unit
- Wiring from Control unit to parking sensors (1 + 3 connectors (?))
- 3 Parking sensors (and clips to hold them to the bumper)
- buzzer and cable to it

I have ordered the cable from the car to pdc control unit, which comes with the buzzer, but I am really not sure which serial numbers I need for the other parts.
Especially the control unit, because there seems to be no visual difference.
There are a couple of models ending in B, C, D, F, H, and I have no idea which one I need.
Additionally, they seem to be for 3 OR 4 sensors, and I don't know if that's something that can be changed with, e.g. ObdEleven.

Any help would be much appreciated. Even if you had e.g. a Xcellenxe Lux (should have them preinstalled) and you knew what the part number(s) was(/were).

I'd love to, especially since you're a sponsor, but I don't really want to drive 350+ miles :/
Also I think it'll feel nice to have done it myself
