Picked up my 2022 ID4 PRO S AWD a month ago and now that I picked up an OBDEleven module I'm going to work to see if with the current software it is possible to enable the Dynamic Light Assist function found in the rest of the world. There is the work of @dg4prez and others trying to enable this in the general OBDEleven master thread, but it seems like working in another thread until (🤞) the procedure is fully figured out.

The information provided by @JimmyVW will be crucial.

Details on how it worked for some Aertons:

When you speak of “Dynamic Light Assist”, to what, exactly, are you referring?
  • The steerable headlamps of some ID.4 trim levels?

  • A matrix LED headlamp system that provides more-complete beam steering?

  • Or something entirely different?

And which cars have hardware that can support these various schemes?

Dg4Prez and I went through a full bit-by-bit compare of the ODB11 backups and concluded you can't get the smart high-beam steering working with the options available in long coding or adaptations.
It seems the hardware and firmware of the led-lights is identical, but the steering option needs a separate software blob loaded into the lights, that simply isn't loaded for the US-spec models.

@JimmyVW I think the current hope is that with V3.1 the additional software functionality will be there for North Amera cars. @Pres is testing on his 2022 that is already on V3.1. I don't know if anyone else in North America has tried with V3.1, but as far as I know @dg4prez only tested on his 2021 model with older software.

He's talking about matrix lighting. The part numbers for the headlamp modules in at least 2021 1st Edition and 2021 Pro S cars match what's been in EU cars that have matrix lighting. I assume this carried over to 2022 higher end models.

happy to have another look at a full backup of a 3.1 car, but I honestly have my doubts they'll include the needed bits until there is approval from the relevant US Federal Agency.
My understanding has been that the NHTSA formally approved the use of matrix/adaptive headlights for use in the U.S. back in Feb this year (2022). Given how infrequent SW updates have been the hope is that VW would have upgraded those bits now for future enabling later.

not only the part numbers, also the internal software and hardware revision match. The lights are identical from a software (ROM) and hardware perspective. But if it needs some blob of data in RAM that isn't supplied, the feature won't work...

Thanks — That's what I assumed but I thought I'd ask!

This might explain an oddity I've noticed whereby there's a slight difference in the high beams when you switch between Automatic High Beams and Always-On High Beams. The top cut-off beam gets slightly higher, as if an additional row of LEDs was turned on. (The weird shadow slots at the center-tops of the beams don't seem to move so it doesn't seem like the steerable headlamps are creating this effect.)

Any help would be greatly appreciated! I have a little hope, but not a lot. I'm still new to OBDEleven so I've just been taking my time reading through things before trying to change any settings.

@VW TECHNICIAN Have any new insight on whether you think 3.1 will work (for matrix lighting in US)?
There is still missing part of necessary software for this to happen.... coding by manually changing various different things is possible but there is need for interlink between windshield camera module and headlight module.....I'm sure that some smart fellas on this thread will get missing things from EU ID4 to flash necessary things for two modules to work with this.
