I own a 2014 E300 Hybrid equipped with the so called intelligent LED light system that follows the road when cornering. Unfortunately there is a dim patch on the right-hand side when on low beams about 5-10 meters out in front, which I find slightly impedes visibility.

My question is, since these are electronically controlled mechanical lights I assume they are also self-adjustable; however, is it possible to somehow tweak them such that the dim patch can be resolved? It feels as if it's a small matter of moving part of the multibeams on the right-hand side a bit to the left. I don't think the bulbs need replacing but I'm willing to consider they might -- how could I test this? The light output in high beam mode is flawless though.

On a slightly unrelated note, the lights can be configured for right or left-hand side drive. What should I pick if the steering wheel is on the left? I went with right-hand side drive since I assumed it refers to the side one faces incoming traffic. Changing this setting does not affect the dim patch in the slightest.

There are no bulbs to start with. These are electromechanical semi matrix LED arrays.

There is no adjustment possible that you can do. The lamps can be calibrated (Star or Xentry) but this needs a target wall with beam pattern definition.

I don’t know what the dark spot is that you refer to. It may be the dogleg for U.K. driving puts a brighter patch on the left side which could make the right side proportionally dimmer.

First off, thanks a lot for your help Craiglxviii!

I was finally able to snap a picture of the dark spot I mentioned in my OP. See here: https://imgur.com/a/outC9GQ (steering wheel is on the left)

Is the dark spot that can be seen in the picture normal? I would have thought that the beam on the right-hand side would extend further out than the one on the left. What do you think?

That looks like the auto full beam system where the light wraps around the car in front , except there is no car there ( if that makes sense)

Yes, makes perfect sense, John. I just hoped there was something that could be done without having to contact my local dealer, book a slot, which will mean being without my car for who knows how long...

^^^This. That’s just what it looks like to me too. The system needs recalibrating and that can only be done in a stealers.

haha -- how much are the stealers likely to pick my pocket for a fix? Also, if I bought the car from an official Merc dealer early this year and it's still under warranty, are they likely to charge me?

Nope it’s a warranty repair.
