Upgrading to Auto On headlight switch?
My previous Olds Bravada had headlights that automatically turned on and off through a sensor. Didn't like it at first but now I miss that feature on the Cayenne.
I read a few old posts that seem to imply that upgrading is as easy as purchasing a new switch with the Auto function. I do see sensors behind the rear view mirror.
ECS sells the switch and mentions it's for vehicles with Auto Headlights or for those wanting to add automatic headlights.
Anyone have success in doing this? One post mentioned having to enable the feature with piwis. I'm planning on purchasing a Durametric Enthusiast kit...would that be able to enable features like this instead of paying a dealer to do it?

My understanding is that there is a wiring harness difference between the auto and "non-auto" headlights.
Retrofitting them is supposedly "not easy".

I have had 2 Cayennes now. A 2006 S and a 2005 turbo. Both were "plug and play" with the upgraded "auto on" light switch. it takes 5 minutes and no coding. ymmv.

I read through all 17 pages and it appears to have a very good success rate of being plug n' play on the 955. Not so on the '08 on up.
$70 switch that was a $610 option.

Dang… I bought from fcp euro, quick plug and play, and…. No auto function. They come on with “on” but not auto in the dark… which was the whole point.
Do you have any suggestions for coding changes with the PIWIS I might try?

No programming was needed on my '04. You can usually find the sensor dirt cheap on eBay and it takes only a few minutes to swap out.

there's a whole thing for enabling it on 957s... involving both vcds and i think piwis.

But the first post articulates what is to be done. I’ll try it today. Thanks!

Yes, my 2009 CTTS needed PIWIS to set headlight assist to on. That’s done and now auto headlights works.
HOWEVER, unlike modern cars, if you leave it set to auto, it still blasts the warning chime at you when you take out the key, as if you had left them on. I think the only thing this does is auto turn them on if you enter a tunnel or whatever. But you would have had to set them to auto for that to work, and back to off for the chime not to yell at you on exit. So it is not “set it and forget it” like modern cars.
So far I’m nonplussed by this upgrade, FWIW.

In my car with factory auto headlights there is no such warning on exit. I just leave it on auto all the time and it works like it should.
The bloody auto wipers still have to be cycled every drive to work though

You can even change the region on your car to anything other than US and the warning will go away for when you have the car running and open the door - I believe that's what I have done. Then, have to go back and change the Mi/KM and F/C settings to your liking in the IC I believe. Clock format (12/24H) may not be adjustable though, I don't recall exactly.
If you can't figure out the proper way to code this, maybe change the region to completely disable the buzzer. Though then will need to make sure that modules go to sleep correctly and there's no battery drain.

Yeah, or I’m just an idiot and the chime was for the key in the ignition. All is well. Just the PIWIS quick setting, swap the headlight switch, and now I no longer have a 1980s headlight switch.
all good!
