Guys, hope someone can help with this one. I have a 2017 Leon ST FR Technology, I ordered one of the headlight switches with the dash sensor from ebay. It was the model for the Mk7 Golf, as I had read that this was the correct one to go for. When I plug it up I can get auto lights working fine, tunnel mode working fine but no Coming home/Leaving home function. The Front and rear fogs don't work either.

The switch I bought is marked with code 5GG941431D. (10 pins) This also came with a 4 inch extension wiring.

The one it replaces in my car is 5GO941431AH. (8 pins)

Does anyone have any pinout diagrams for these switches to see if its possible to change the extension wires to see if this will work with my Leon.

TIA
Raymond

That's strange, I replaced my 5G0941431AH by 5G0941431AF. And I just looked at my old switch 5G0941431AH. it has 10 pins.
Fog lights should work out of the box, however for coming/leaving home you need to change the ECU coding using VCDS or OBDEleven
