Rain sensor in KL mk4 Leon?

Excuse me. What is that means? Thank you.
it means your car doesn’t currently have auto wipers, 8N6 is with automatic lights and wipers.

Try the changes I listed above. If it works then ETKA & parts link are correct and you have the correct sensor

If it doesn’t work then ETKA & partslink are wrong (to be fair partslink data comes from the same system as ETKA), and you don’t have the correct sensor installed. Install the correct sensor and with those coding changes everything will work

Thank you. This code in the photo must be active? Asked gpt and said it must be inactive.

Lastly, I need rain sensor and wires? And ideas that are the part numbers and from where could i buy a kit? I find it very hard to remove all trims and mirrors in this car
Thank you

The list I gave you is a car without vs a car with

The minimum you’ll have is a humidity sensor. The wiring will be there. The part number is on both of the screenshots I posted highlighted in bold text

Try the list I gave you, if it works then great. If it doesn’t, order the sensor and install

There's coding in A5 too, in addition to the list I posted

Hi @East Yorkshire Retrofits , I'm trying to enable this in my Seat Leon mk4 and it fails for me with "Functions cancelled, marginal conditions have not been met" when I'm trying to do the following step:

RLFS_RLS Codierung (KII05)
Regensensorbetrieb Aus -> Ein

All the other changes worked! It's only that one that I can not enable.
Any idea what am I missing here ?
Thanks!

I am using the OBDeleven VAG (so pro verson) and I am getting an “Unavailable” when clicking on the Subsystem of 09

is this expected? Or any idea how else to get the sensor PN ?
