Dragos - I'm confused. As far as I know all Cayennes of the 958 series have HID headlights. At least in the US. Do you have a link to the Hella LED headlights?
Trying to change xenon headlights with LED
Hello, guys.
I have a 92A Cayenne from 09.2016. My xenon headlights keep fogging and I already changed the left headlight as it wouldn't work anymore.
Now the right headlight seems to fog so bad it will break.
I want to swap/retrofit/change the current headlights (xenon) with full LED headlights. I found HELLA LED headlights and some videos that show the change is basically plug&play.
Any ideas? Will I have some sort of error notifications? I haven't changed anything to this car yet and don't want to break anything.
Thanks

Thank you for your reply. I don't know how it is in US, but in EU, or at least Romania, Cayennes 92A don't usually have LED headlights. We have xenon on low beam, and halogen on high beams (H7). But, after a few years, the headlamps get old, I guess, and the fog. After a few months they stop working as all the internal components get wet. I changed the left headlight at the only Porsche dealer in Romania, with aprox $3000, but I thought that if I change them intro LED headlights, they wouldn't have this problem anymore.
Here are a few links with the Hella LED headlights I found:
- a romanian online shop
- design911shop.com

Dragos - I suspect what you're calling Xenon is a high-intensity-discharge (HID) light source. This is basically an arc lamp (arc discharge between two electrodes). US 958 had HID "bi-xenon" lights, where the low and high beams were provided by the outside light source, using a shutter to block light for the low beam and open it for the high beam. The "flash" high-beam (triggered by pulling back the turnsignal lever (ie - "flash to pass") is a simple H7 projector. Those are only illuminated when the turn-signal lever is pulled back. The lights are self-leveling (a requirement in Europ for HID lights) and "Litronic" which implies some steering of the light beam in response to the steering wheel position. On US cars - turning into a corner turns on a separate light source in the headlight closest to the curve that points to that side of the car illuminating the corner. Later Litronic lighting also steered the low-beam light in response to road speed and curves.
As far as the internal components getting wet - that's surprising since they seem to be fairly well sealed, but it sounds as if something happened to yours there they're allowing water inside the housing.
I noticed the one listing you had for the LED lights said they were for right-hand-drive cars.. I'm not certain what side of the road you drive on but I'm going to guess that your steering wheel is on the left making it a left-hand-drive car. It would be worth checking this with the vendor I imagine.
To answer your question on the bulb-out warning, my guess is Hella has taken this into account in the design of the lights - I can't imagine they don't - and it would be an issue. It certainly might be wise to contact Hella to confirm this before spending that much money.

Your answer was more than I expected! Thank you.
I will contact Hella, just to be sure about my decision.
