I have 8JU (black variant).

Edit: I should add - I do see matrix as an option and enabled under Settings > Vehicle > Lighting > Exterior Lighting, but on the road, headlights behaved as adaptive high-beam assist only, which essentially de/activates high-beams in their entirety, rather than matrixes, depending on upcoming traffic.

Cool....looks like I have 8IU on my car.

Reading that Cayenne thread it looks like only one guy got it to actually work and several others have been unsuccessful? The video he posted of the matrix lights in action is pretty sweet though.

Were you going at least 30mph? I'm also curious -- what version Piwis 3 you have? I have 40.900.020

I didn't check the speed, but I was testing on the highway so pretty certain I exceeded 30mph. I was using PIWIS 3 v.38.25 in engineering mode.

So far, only one person started to test it, but his independent mechanic only had an official PIWIS connected to PPN. I don't think that's gonna work. The user did not want to connect a modified PIWIS to his car.

I don't have those features on my Cayenne, either, but I had previously enabled other features on my car (intersection lighting, for example). Maybe that's part of the difference.

Did you leave 8G4 configured after the second round of coding? Were the Panamera settings even the same as the Cayenne? Evidently 992's are slightly different.

Thanks for venturing over to the Panamera forum @runbuh . I would be glad try out intersection lighting if you could share the control unit / coding value(s)! I did enable Crossing Assistant under BCM1 but that is using the ultrasonic parking distance sensors.

Re: Matrix, I followed your steps using E mode on Piwis 3 v38.25 in the 4 following settings under Add. Menu / Maintenance of Vehicle Data

• FAHRLICHTSCHALTUNG from 8K5 (USA) to 8K8 (ROW) back to 8K5
• LICHTASSISTENZSYSTEME from 8G1 (PDLS+ Fernlichtassistent) to 8G4 (inkl. Matrix-Beam) and left unchanged at 8G4
• LINKS-/RECHTSVERKEHR from AV2 (NAR) to AV1 (Rechtsverkehr) back to AV2
• TYPPRUEFLAENDER from B34 (USA) to B02 (Belgein) back to B34

Can try again tracing your steps including the coding for intersection lighting, LMK.

Let me find the other settings I enabled (may take a few days - I gotta go hook and poke around a bit).

What year Panamera do you have? I thought 2019+ models required PIWIS 40.xxx to do full coding?

c17r15

I have a 2018. No issues in v38.25 in E mode. I can try to code in V mode in v41.10 too.

Off topic but I'm interested in the Crossing Assistant -- mind sharing how that is done?

I ended up coding RCTA (Rear Cross Traffic Alert) as LCA variant under Maint. of vehicle data instead of coding individual control units (BCM1, ESP, RVC, etc.). Apparently RCTA requires at least an additional proximity sensor in the tailgate that my car does not have, resulting in some unclearable braking and PDK errors, so I reverted back to LCA sans RCTA.

Yet another standard safety option on most cars that we don’t get.
