Automatic headlight function

Does anyone know if it is possible to retrofit the automatic lighting function? My car has a sensor on the windscreen that dims the PCM and instrument lights when it gets dark and I'm wondering if the correct headlight switch was fitted it would also turn the headlights on when it gets dark. Mines 2012 car with PDLS. Current switch just says 'home' in the central position rather than 'auto' as I've seen on other cars.

    Regretably Simon, I doubt that it's as simple as just changing the headlight switch.
     
    I've no idea what would be required but if you're really keen I'd speak to your local Dealership to find out if they can help. I'm sure that it would be costly if they're involved..!

    I’ve found that OPC’s don’t want to do anything out of the ordinary. I contacted several dealers to try to get the steering wheel in my Cayman GTS changed from a paddle wheel to a button wheel (I only have one arm so it would mean I could gear up and down with one hand). I don’t think it would have been a cheap job to do knowing the price of Porsche parts but they all said it couldn’t be done. This surprised me as a bog standard cayman with PDK would have had that exact wheel, so why wouldn’t it be possible to downgrade to one ? In the end I bought a wheel off eBay for £110.00 and fitted it myself with no problems at all. I think your best bet would be to find a good auto electrician and ask him to give it a once over to see if it’s at all possible.

    Hi
    I think that you'll find that all these things are possible - OPC won't go near them though for a number of reasons (mostly involving warranty, how much cash it generates for them, and knowledge)
    To upgrade to auto headlights you just need the necessary hardware, (switches, ecus, etc) and the wiring in place. You will then need to get it enabled on the car by changing the vehicle order with PIWIS.
    To find out about the hardware you need, see what is installed in your car, and what is needed for the option - check the parts lists, plenty of people have them - then check the wiring diagram for your car.
    Once you know what the differences are - off the top of my head - i think they are minimal you will then be able to get a picture of whats involved.
     
    I suspect that it is only likely to be minor changes though such as the correct switch and sensor followed by enabling the option.

    Thanks that's interesting as I was wondering about changing to the polished alloy centered paddle wheel from the button wheel I have on the current car. I had the former on my first Cayman and preferred the look of it. Looks like I was not loggged in first time!🙂

    Simon, it sounds as though you ought to PM Giby in case he still has the paddle wheel, they can be quite expensive to buy for the upgrade and difficult to even find.
     
    And if you do the upgrade to auto lighting please write an article for the forum.
