    I have a Seat Leon FR 2014 without rain sensor and auto light lights.
    If i get these parts HEAD LIGHT SWITCH 5G0941431AF and RLHS Sensor: 5Q0955547A
    I think the RLHS Sensor: 5Q0955547A will be ok.
    But i am unsure if i need a light sensor wire to go with the HEAD LIGHT SWITCH 5G0941431AF
    So do i need a light sensor wire AND auto light switch if i get genuine parts ?

    Nothing i don't think .. compared to my last car ..Scirocco had auto lights and behind the mirror on the windscreen looks different ( plain looking, no sensor pads or anything).

    If there are no sensors at all fixed to the windscreen (take it you don't have climate control then?) then yes you'll need some cabling.
    Cabling between where and where I don't know as its not something I've looked into.

    Either the information is already on the forum somewhere or hopefully someone who knows will be along soon :)

    Cheers.
    I will have to have a good look at the windscreen then.
    At first glance all i can see is a black pad ...

    That appears to be a MK7 Golf switch so should work OK, but will have white back lighting rather than red.

    On another note when replacing the Humidity sensor for the Rain/ Light sensor do you need to remove and replace the gel pad or can you just fit it to the existing pad?

    Can I fit the new sensor and leave my eBay auto light switch installed and get wipers to work without coding?

    This will be temporary until I can find the correctly coloured switch

    U can use the 1 already installed. The only thing that works without coding is the rain sensor, rest will need coding

    Thanks, I’m only interested in wipers at the moment as I have the eBay Auto light switch/ sensor that works fine, but when I find the correct SEAT light switch I’ll swap it out and code up the new switch with OBD11

    Another thing if someone can answer.
    The china light switch comes with a light sensor wire.
    If i manage to get a genuine Seat light switch will i need a light sensor wire or should it already be in the car somewhere
    and match up with the genuine Seat light switch ?

    To get seat spec auto lights you need to replace the switch and the sensor located inside the rear view mirror casing, no wiring required as long as you have climate control.

    Can't remember my switch code (it's up in this thread somewhere along with my Obdeleven guide) but it lights up the right colour (not white like a golf one will) and it came out of a Polo GTi.
