It's this system.
This is the headlight I have.
There are also no facelift W212s with xenon lamps. 2013 was the last year for HID/Xenon in the US and 2012 was the last year for it in ROW.

Now, here are Mercedes LED lighting headlamps, between all the vehicle classes, which adds to ILS functions and capabilities - A look at your headlamps should tell you what they are, the words are molded into the housing.
Dynamic Full LED (pretty much the same as xenon, different “bulb”)

Active Multibeam LED (24 Individual LEDs):

Enhanced Multibeam LED (84 individual LEDs):

Digital Light (1 million pixels):

To describe headlamps by years is much too difficult as there are overlaps between the model classes. Hopefully, this clears some things up.

In Europe you were able to get the w212 facelift with xenon lights, like this w212 shows.
As for your issue, my car behaved oddly after I hit a deer and it let water into the control module on the right side. You really need to hook it up to a Mercedes scanner.

Yes, I will try getting it scanned by a Mercedes scanner next week, I'll post about it later.




Sorry, I was traveling yesterday so out of touch, seems LB took good care of you! And is right!




My USA model 2016 'luxury' e350 has option 640 - SAE dynamic LED headlamps, right-hand traffic
I gather these are not the same as the ILS ? The other night when I turned them on in my driveway, I distinctly saw them coming on while aimed down, and coming up to their normal height. are they just fixed there once they are up, or do they have any additional adaptations, such as load leveling ? from behind the wheel, the high beams sure look like additional LED elements that fill in the upper half seamlessly and are instant on, instant off.

As of right now your car will turn the lights with the steering, switch on/off the high beams automatically depending on traffic, and auto-level. They are full LED so the high beams are also LED.
If you code the full ILS in then it will do those things, have motorway mode where it adjusts range/width of beam based on speed, have enhanced fog light where when the rear fog is on the left headlight dips and swivels to make for a low/wide coverage area, have adaptive high beam assist plus which means that it will mask off other cars instead of dimming the lights. This gives the effect from the driver seat of the car wrapping light around the car in front of you. Both sides will be lit up but it will not dazzle the car. There are other things I am sure I'm missing but those are the big ones.
The following codes appears:
Right headlight: B284D71
Left headlight: B284D71
Does anyone know what to do?
Sorry for the bad image quality and the text is also written in Finnish.




Wouldn't want to replace both headlights, because Mercedes is asking 3000€ for just one headlight without the two control modules.




I did find the motors for sale in the EU for not much, like 33 Euros, I have no idea the difficulty in changing those out, nor have I heard about this being a regular issue with these lights.
Although my Finnish is terrible, I did understand what the code was saying! I do know there was three renditions of the xenons in the '10 to '13 cars, but the old part numbers are superceded by the "13 part number.

Adaptive "A" symbol shows normally, and Lights move normally At car startup. Adaptive high beam wont engage at all.
Has anyone had these kind of symptoms and had problem solved?

Did you found what is the issue and how to solve it ?
I do have W212 2014 with ( Adaptive Highbeam Assist Plus + LED Intelligent Light System ) and my car have the same issue you have it in your car ( except it is for left side ).
the local workshop use Xentry scanner and give the same code:
B284D71 ( The actuator motor for the light distribution has a malfunction. The actuator is blocked. )
Xentry Report
any Idea ?
