so i have a humidity sensor in my car atm and im going to replace it with a rain light humidity sensor, but the only problem is coding. does anyone know how to code the RLHS?

If the RLHS is the "normal" type, then it will not be connected into the CAN network as a main module. Instead, the RLHS will be connected into the CAN network as what's known as a "Slave" module to the central electrics module. OBD11 calls these slave modules "Subsystems". Because of the master/slave topography, communications between the RLHS and the Central electrics module occurs over what's called a Local Interconnect Network (LIN) which is a single wire comms protocol. So that's the theory part - the coding reflects my description above: First - Install the RLHS and tell the Central electrics module that you have installed the RLHS - via LIN protocol Then check that the RLHS is correctly registered (note depending on the RLHS that you fit, your coding might be different) Don

I retrofited 5Q0 955 547 and it works. I am from SLO (EU).

I didn't code for a long time, so you can ask Don If you really need to do all above...

the only coding i did was to set the rain sensor to active and everything is working now

Yeah I also retrofited auto light switch so that was a little bit more tricky... 😊

Hi thanks for this great guide I have followed it as best I can but when I get to the but in the second picture after pressing sub systems the rlhs do not show up any ideas please. This is on a 14 skoda octavia thanks

ok tnx for taking the time to reply, i'll do it but i cant find the part number for the RLHS for my specific car i found 3 p/n 5Q0 955 559 8UD 955 559 B 5Q0 955 547 which one is the correct one for my car? cuz i want the car to recognize it and so i wont have much trouble coding. Hi thanks for this great guide I have followed it as best I can but when I get to the but in the second picture after pressing sub systems the rlhs do not show up any ideas please. This is on a 14 skoda octavia thanks have you done this part? without it your car wont know it has a RLHS installed.

Hi all, I have just fitted a RLHS to my 2017 Seat Ateca and following Don’s instructions to long code it to the car but I don’t see any textual comments and the long code string is all zeros. I read that this is common with newer MQB based cars, so now I’m stuck. Not surprisingly I don’t see the RLFS in Central Electrics > Info as it’s not yet coded. I looked in Adaptation and saw Front_wiper > Regensensor aktivieren = Not deactivated. Is this where the sensor is enabled? Can anyone advise if there’s another way to code the sensor? Many thanks,

I looked in Adaptation and saw Front_wiper > Regensensor aktivieren = Not deactivated. Is this where the sensor is enabled? Can anyone advise if there’s another way to code the sensor? Many thanks, tango: Of course without more information I'm guessing - but in newer model mk7s which is a MQB platform vehicle, there was a major change to the module that OBD11 calls the central electrics module. In these cars, the adaptation channel database was dramatically altered and ALL of the old software switches that previously appeared in the code section of the module were transferred to adaptation channels. This had the result of making the already large channel count in the central electrics module even bigger! In these cars, diagnostic devices like OBD11 report a zero code-string , so I'm guessing that this is what's happened in your case.
So - to your question and assuming that your Seat Ateca is the same as the new mk7 - what you need to do is the go to the main screen for the central electrics module, then select adaptation, then search for "Assistance light functions", then select Assistance light functions-Regen_Lichtsensor, then set the value to LIN_REGEN_LICHT_SENSOR (assuming that the RLHS that you installed was a LIN device). At some point in this process, OBD11 will ask you to enter the magic number 31347 .

Hi Don, Thanks very much for the advice, it was exactly as you described. I managed to get the auto lights working perfectly and I coded the auto wipers too but I’m not sure if they are working correctly at the moment. They appear to be very insensitive and when they do wipe they don’t stop!

Hi my friends. I try this method in my octavia 2018 „ for the central electrics module, then select adaptation, then search for "Assistance light functions", then select Assistance light functions-Regen_Lichtsensor, then set the value to LIN_REGEN_LICHT_SENSOR (assuming that the RLHS that you installed was a LIN device). At some point in this process, OBD11 will ask you to enter the magic number 31347
But i have a problem, evrything works good, but my octavia have a error, when the switch is in auto, this error is : interference: car lighting Pls help me

I finally found the solution to getting the rain sensing wipers to work on my 2017 Ateca. I had fitted several different RLHS sensors with part number 5Q0 955 547B which all the websites I researched said was correct for my car. This sensor worked intermittently and always wiped 3 times instead of once. I recently tracked down a genuine RLHS sensor from a salvage Ateca on eBay part number 81A 955 555 and it works perfectly. It might be the same part for facelift Leon's too.

I checked ETKA, it says 5Q0955547B or 5Q0955559B.
No mention of 81A955555A on ETKA.

I read it's commonly fitted to Audi A4 and A5'S so yes, those aren't MQB platform cars but the eBay seller says this RLHS came from a 2017 Seat Ateca and it works 100% in my car. Does seem odd but I'm just glad to finally have my wipers working correctly!

I should add that I posted this info on Cupra.net and someone replied saying they had to use the same sensor on their 2017 Leon to have proper functioning wipers. Just want to share this info to help those with later cars.
