Rain/Light Sensor Coding Mk3 FR

[Giuseppe Busso]

Hi Giuseppe,
okay then you had the same original sensor as I installed.
It only works with the sensor 81A955555A !
All others do not work without error message.

If i leave it as it is, will i have any issues? except of fault?

Should i buy a new one (proper code)?

So this fault is from the sensor? right?

Just a quick note but if anyone has enabled cornering fogs and they also want both fog lights on when in reverse like the factory cars and Mk2 Leon then this is the coding: ---------------------------------------------------------------------------------------------------- Activation of the...

@astaller thank you

I don't know if there are any other restrictions.
That's right, the error message comes from the sensor.
If you want then buy the sensor from Aliexpress.

@astaller

Thanks for the info mate, also for the codings!

I did a reset on the infotainment. I think that my issue with auto wipers has got fixed now.

So i'll keep with that sensor installed and sometime in the future i'll change it.

Thanks, i appreciate your help.

Good morning. I have checked your attachment with the settings.

Yesterday, we checked another Seat Leon FR Model Year 2018 with the convenience pack installed from factory and i observed that there are some different settings according to your attachment.


First of all it has the proper sensor (81A955555A) as you can see below:



The sunlight sensor is by default installed (same setting as in file)



But here you can see 4 different settings:






My friend's Leon has:

1) Terminal 15 instead of ENG122229-ENG117715-Car_Function_List_BAP_Gen2-wiper_comfort_0x0C_msg_bus -> Datenbus Komfort (comfort data bus)

2) 18lx instead of ENG141656-ENG116605-Außenlicht_uebergreifend-Helligkeitsschwelle Infrarot-Messung -> 0 lx

3) Not available instead of ENG141684-SFT271874-Slave_systems_identification-Sensor für Regen- und Lichterkennung -> verfügbar (available)

4) Hinweis_in_LDS-Stellung SL instead of ENG141656-ENG126818-Außenlicht_uebergreifend-Fahrlichtwarnung_Hinweis_Konfig -> Hinweis_in_LDS-Stellung_Null_und_SL


So?

Hi all,

I'm new here because I have searched hi and low to find an answer to this.
Does anybody know what the bytes mean in the light/rain sensor ? In the first post they are speaking about 00095D. My car has 0018DD.
In some other thread I found (vcds), someone said :

Is this true ? Can someone confirm this ?

Regards,
Jacco

So?

Hi Guiseppe,

please excuse me for being so late, did not get the message.
Yes, that's how everything should work.

Hi can anyone confirm what sensor I would need for a 67plate Leon as don’t want to order multiple ones ??

 

[Alister]

Hi, I installed the rain sensor as described, the automatic wipers worked for a while and then stopped working. Can you help me ? thank you

Hello, I have one question. I have a 2017 facelift Leon fr and just changed the sensor with 81A955555A, did all the steps but from the drop down coding page, it showing me the old sensor. I did a long coding (00885D) to it. It works but the naming remains. Is it normal or does it have to recognize the new sensor name?

Just checked the soft reset when reselecting LIN_REGEN_LICHT_SENSOR and my sensor appeared as it should at the coding page.

No fault now at the scan process? I have to do the same. Leon FR mk3.5 here too.

I have the 81A955555A sensor. For now everything works and i don't have any faults stored yet.


Edit: i also changed the coming home to automatic from Car Scanner pro, but how do I add this option on my mib2 screen?

I don't believe that you can add this option. Have you chosen to enable it via driver's door?

Yes I've enabled it via driver's door. I can choose the seconds or off for each coming or living as before but at my parking there is no good lighting and my headlights turn on every time i take the car, so i would like to have the option to have the coming leaving home manually and enable or disable the automatic but nevermind, i'm asking too much. I'll disable the automatic come/leave home and switch my lights on when needed.

Does anyone know how to code it in with obdeleven on iPhone?
