So, In looking at the LED headlights, wondering if anyone had them fail on their 9Y0 and what was replaced? It used to be a simple usually cheap bulb to replace, now with LED in looking at the diaghram the only replaceable part I see is an LED control module. Is this LED control module essentially the bulb change? If not are we down to spending 2,3, 4K depending on your model for a headlight, or search ebay for a used one?

 

Dealer will likely replace the module first (if there is a fault code that links to it). If it is the headlight itself, whole assembly + reprogramming are the typical fix.

Hopefully, your vehicle is still under warranty.

 

Nothing wrong with my headlights, just trying to figure out what I'm in for if they go. Wow what a downgrade from a cost perspective with LED.

 

well compared to my former Kia Sorrento headlights, I'll take my 2024 Cayenne LEDs anyday. They are expensive to replace. I looked into it briefly and I think the modules are $1900 or something each? Part of the cost of a luxury SUV..... Always keep $10k lying around for whatever is needed (brakes, tires etc)

 

Let's hope the aftermarket with LED repair services comes to the rescue. The cost is completely ridiculous, and not just Porsche others are following even cheap brands. I've seen articles where cars in the future may be totaled just due to the headlight cost, utter craziness.

 

it may happen (aftermarket) but doubtful. Usually they don't work, because they don't have the magic sauce that the OEM parts do. I tried that on an older generation BMW X5, bought some off Fleabay "guaranteed" to work, and they did for about 60 days, Vendor would not honor any guarantee so I had to replace with OEM from the Dealer.

Porsche is a lux brand, and priced accordingly.

 

not surprised. i worked for toyota in the early 2000s and we had a number of newer cars totaled in minor accidents because of body damage but the airbags in the driver seat deploy pushing the repair cost over the edge. $6k+ for a seat.

 

The left headlight on my 2015 Cayenne 958 turbo failed last weekend, generating multiple error codes for dipped beam, main beam,and cornering beam. This can't be failure of all the bulbs at once; it must be a “control module.” I've been unable to find troubleshooting instructions in the 11,000 page factory repair manual, and online parts listings show multiple "control modules." Is anyone aware of a good source of information, or of a repair service?

 

I mean, are we really worried about LED modules failing?

 

And Porsche is a downgrade from a Dacia from a replacement cost perspective . Something better will always be more expensive to replace. But it's even better in this case. LEDs have 20-100+ times longer lifetime than standard bulbs and live nearly as long as other electronic components - decades. They can still go bad but that would be more like an electronic component dying rather than a lightbulb - a very unlikely event rather than a periodic expense.

Also, if comparing LED matrix lights to high-end Xenon lights, it's actually an upgrade in terms of long-term cost because LED matrix lights no longer have a swivelling mechanism, which is more likely to break than LEDs and would also require replacing the headlight. So it's better from long-term cost perspective. Consider this - long-haul trucks and trains switched to LEDs long before cars precisely because of lower long-term maintenance and replacement costs.

 

The MTBF (mean time before failure) is like a magnitude of 10x or less than that of HID or halogen headlights. .Most owners would just get a warranty claim and have them replaced. I don't know if you're fear mongering or working for the other side . I recommend we delete this post.
If you can't afford it, why are you dissing it?

 

The concern is completely valid in my opinion - particularly for those for those who, like us, usually keep vehicles long past their warranties. I was once very concerned with LED anything on vehicles based on the countless vehicles I've seen with failed LED's in rear light units - Japanese and German vehicles and especially Mercedes vehicles including a friend's SLK230 with failed LED modules in its CHMSL. I was apprehensive about the headlights on the Prius we bought for my wife in 2012 since it was the first Toyota brand vehicle with LED headlights and Toyota had been using LED headlights on Lexus vehicles only since 2009 and originally only on the LS600h hybrid which was its most expensive vehicle.

I don't think it is clear yet whether or not the Cayenne's LED headlights will age well. For those who will own Cayenne with LED headlights well past its warranty, the cost of replacing a failed LED headlight unit will likely not be cost effective due to the market value of the vehicle.
