Matrix LED Light Issue

[Rusk]

I will have to try and find a nice wall for this. I got my car back and of course it isn't fixed. They had the car for a week and did yet another "calibration" which is code for plugged in and and installed the same image they did last time hoping I would just go away.

ugh, how frustrating...
If it helps, although I finally found a big flat wall where the car could use the full height and width of the headlight throw and you could have projected a movie on there nicely if you wanted, the actual headlight calibration bit only used the lower meter or so of the wall to do its business. So I imagine you can likely get away with a fairly low wall to do this.

So the automatic calibration definitely helped with my car blinding oncoming traffic to the point I feel that's solved, but I still get the issue with the box the headlights draw regularly covering the left hand edge of the car in front. I managed to get a recording which shows what happens. It occurs when going round right hand turns on a bendy road following a vehicle.

Is this the same behaviour you have with yours @Rusk ?

I have my original service appointment coming up next week so hopefully they can find something to do which helps with this ?

 

[Rusk]

Yup that is exactly what it looks like to the left side always coming across the back of the vehicle in front.
Mine is due into dealer again end of September for the recall and a new camera to be fitted. Let’s see what happens with that.

so my car went in for its service appointment to look at the headlight alignment and I included the video above in my description of the fault, but the message back from them was basically "that's normal" ?
I pressed the service manager a bit when I picked it up and said my experience of the same headlights in a Macan is that they're perfect and not like this. He agreed that it was definitely a bit crap, but that in his experience the Taycans are all like that... ? He did say if I got more video footage and put a clear case together he could pass it back up to Porsche and ask for a second opinion.

One random thought I had last week was whether this might be happening because my car has rear wheel steering? ? @Rusk - does yours?

 

[Rusk]

I had that from them, that it was normal but I insisted they lent me another Taycan with matrix and they worked perfectly. I didn't get flashed once and the window to the left side of the of the car I was following had good clearance nothing like mine or yours does with the overlap.

My car is booked in again in two weeks at Nottingham so lets see what happens this time!

Nope thats not the reason either. I have RAS and on a prior Taycan and neither had this issue.

 

[Rusk]

Sorry should have added my car does have RAS

 

[DWJames]

@Rusk did you ever get anywhere with this on your car? I didn’t…
Mine went in for service yesterday so I have a loaner Macan Electric with matrix lights overnight and they’re perfect. The light pattern leaves a nice sturdy border around other vehicles. So I’d like to press them again to get mine sorted, but wondered how to progress it.

Nope. They had my car for a week and on two evenings one of their sales guys took the car home and reported no fault found.

I am convinced they simply drove through urban areas where the beams don't work anyway it is crazy.

I drove home that day and went out on the country lanes where I live and was flashed by every single car that went past me.

Nottingham have no interest at all in having the car back and I'm very disappointed. This was a 1K option and it clearly isn't working properly. Why a sales guy took it home I've no idea and not a mechanic able to troubleshoot. When I looked on the tracker they didn't go out after driving home to test it on different roads. When I said it wasn't troubleshooted at all they claimed the chap drove it and said no issue at all.

As you've seen with your loan car I had a loan Taycan and the matrix system worked perfectly. No flashes at all and nothing but flashes in mine.

I've given up at the moment as I don't want to stress anymore about it. I simply won't be buying anything more from Nottingham or perhaps Porsche, we will see.

 

[DWJames]

Nope....

How very frustrating. Like you I ran out of energy with it and got used to having to operate the full beam manually (cos I can't even set it as a basic auto-high-beam, it's either matrix on or off), but having driven a vehicle with the lights working as intended I'm motivated to push a bit more and see if we can get this resolved.

 

[DWJames]

as I said, system is great but won't be perfect. led and matrix will always be flashed back du to the brightness and the whole system.

Thanks, but you're missing the point of the thread. Both myself and @Rusk are really happy and quite impressed with how the PDLS+ matrix lights work on the Taycan and other Porsche vehicles with them fitted. The issue is that on our specific cars, it's not working like they usually do, but because there's no fault codes and it's hard for a service centre to test (because it needs a test drive on unlit roads in the dark) our concerns are being dismissed and we're both just being told that our cars are operating as intended.

When are we gonna get this in the US ?

Rivian already has it the US. So the question is, how far behind Rivian is Porsche?

 

[whitex]

US came out with different rules for adaptive high beams than the rest of the world. So at the very least Porsche would have to recertify their designs. Some of the differences are performance/accuracy (e.g. reaction time, how accurate it must be if for example the car is bouncing up on the road causing the headlights to point more upward), and others are how they must be tested for certification (e.g. use range of real cars vs simulated blowup cars).

From what I heard Porsche old matrix would not pass new certification. Also sadly, each model year would have to recertify up to latest requirements (not the requirements from when they were originally certified but new headlights rules) so a complete non-starter. Whether the new matrix headlights can pass is unknown, since they were designed before US had the new rules (completed very recently). Enabling on older model year will still be the same challenge with having to recertify older model years.

So for now, US drivers are stuck with automatic full high beams or nothing (manual activation), unless if course you hack your car.
