    The rain sensor I installed has 2 sensors on it, with this I now get auto wipers.

    What's the extra sensor on the pic below for? Anybody know[​IMG]

    just to put it here as I struggled a little bit to remove the rear view mirror. There is a lock mechanism between the fork ( an angled shape which prevents the mirror assembly to turn anti clockwise. The correct way is to pull the mirror assembly down ( the clamps allow it to pull a little bit) and then turn it anti clickwise. SkHkHCc-min.jpg

    this is the old model of sensor. the new one only has 2 diodes. Did a lot of searching around internet before installing myself.

    I dont see the RLHS option in the coding area, does this mean I got wrong sensor in. Will take a picture of it when i get in my car.

    Also, when i install my auto light switch, I get light error, and the fog light is lit up on the switch in all settings(off auto dip and full). Ive done the above adaption for 2017 model exactly. Any suggestions? Thanks

    could you extract the adaptation map from vcds in excel. that would help understand why you are getting light error. correct me if I am wrong, you get full-beam and dipped beam on when you put the switch to auto, and on the screen you get light error? I remember I also got this while I was using some trial and error approach.

    Make sure that you have

    Is there a definitive guide to coding the auto wipers and lights for a Facelift using OBDEleven, apologies if I have missed it.

    did it fix the light fault? In the RLHS coding, you can use the long coding helper. I remember I had to select the vehicle model in Byte 1 section of long coding. ( use 06885D )

    Also, if you put the light switch to position or dipped beam. it should behave same as the old switch.

    Yes i selected leon 5f, but still have the same issue. Could the switch be faulty?

    My friend has a 2017 gtd, il try switch and see if it works.

    Il also try out the code you've mentioned

    Could be faulty switch also. If you can get hands on another switch, try swapping it and check how it behaves on all other modes apart from auto.

    I cannot see the file attached.

    I just changed my LDS_mit_AFL configuration from Yes to No, and I am also getting the full+dipped beam with foglight along with the light fault error message. (Only when i put it in auto )

    If you scroll up, you can find my previous post with link to google drive, where I have uploaded the adaptation change log and all screenshot I took for every step ( some steps were to rollback previous changes too ). I take screenshot of every change I do

    I think this setting is causing the error. Try changing the below configuration. it should remove the error.

    ENG141656-ENG142034-Außenlicht_uebergreifend-Light_Control_Module installed. --> change to 'Not installed'

    I have my auto lights working, also coming home and leaving home works perfectly. I run down to my garage and send you the adaptation map I have.

    are you getting the light fault only when on Auto mode or in other modes too ?

    EDIT: attached adaptation file, There are two worksheets in the file, Sheet 1 is from my car. Also got the screenshots for the RLHS Sensor, uploaded here.
