Coding and programming - Retrofit Heated Fan Washer Jets

Hi guys & gals, Today I'm going to explain how you can fit heated fan jets to your Leon and how to wire them in. These came as part of the 'Winter Pack' but can be wired & coded in with relative ease. This is relatively simple to do, and doesn't...

I’ve literally been searching for wiring diagrams for weeks for this retrofit! Thank You!

I’ll also be doing the level sensor which you’ve also written up. Did you buy a repair connector for the sensor with the wires already fitted as the pins look to be a different type to the ones documented.

Glad the guides helped out. The level sensor I got hold of already had the electrical connector still attached. The part number for that particular connector is 1K0 973 202. I've attached a picture of how the end looks

Thanks for the guide Lozzy, seemed like such a good idea starting it yesterday afternoon when it was light coding it this morning so I can hopefully confirm the coding on a pre facelift for you!

Coding on a pre facelift is via the long coding helper and it’s Byte13 Bit 4. Byte 14 is for the washer fluid sensor.

Thanks for the info! I'll add it and credit you in the guide. Managed the install all ok? The BCM is a pain to get out.

Yeah the install was no bother, did both of your guides at the same time. I found it simpler to just remove the connectors for the BCM in situ rather than removing the unit.

That is an easier way if you can get them out. I couldn't, hence ended up removing it.
