Hi.

I installed the ALWR system from Kufatec. Everything seems to be working fine so far. The values are correct, and the headlights are adjusted. The headlights also move down and up repeatedly when using the actuator diagnostic function. However, when I, for example, load the trailer hitch with weight (e.g., 115 kg), the system doesn't seem to adjust. Does this only work while the vehicle is in motion?

Best regards, Bolzer.

Do you know the difference between ALWR and DLWR?

The A system activates the low beam headlights once when the vehicle is started and that's it.

Only D is constantly fiddling with the light.

Factory-installed Xenon headlights on the G4 models have a rating of "A", while those on the 3C models have a rating of "D" (which is noticeable when braking harder).

Okay, please provide the German text you would like me to translate into English. I will only provide the translation.

Hmm.
Okay, so it adjusts once when you start driving, and then doesn't adjust anymore. Am I understanding that correctly? This means that if I drive to our construction site, leave the engine running (we have something like a drive-in for building materials), load 10 bags of gypsum into it, will the system not detect that? That would be bad. I thought it was supposed to handle things like that.
Best regards, Bolzer.

That's exactly what differentiates "automatic" from "dynamic" for me.
I'd be happy to ask my friends who also have a Bora with xenon headlights.

My knowledge only applies to original VW vehicles that left the factory with LWR (low beam range) systems.

Okay, so if you load my Golf with Xenon headlights while the lights are on and the engine is running, it does adjust, but very slowly and sluggishly, which you can clearly see if you're standing in front of a wall. There's definitely nothing dynamic about it. It's basically just a replacement for the leveling switch. After all, nobody fiddles with that every time they hit a pothole. If you change the load on the Golf (quickly), you won't see any adjustment...

Ha.

That's definitely worth making into a movie icon_smile.gif.
I'll post it in the movie thread.

That will be a long one... instead, create a log of a headlight control unit icon_smile.gif.

Thanks to DLWR, it's very quick.

"You're right, I could simulate a scale on the CAN bus that would display the load in the trunk based on the amount of suspension travel."

Hi.
Okay, thanks for the information. I'll take a look at it when I have some time.
Best regards, Bolzer.
