Lightbulb Intelligent Light System Sluggish

My ILS works fine and i love this option, use it almost daily (nightly). I have a W212 2013 Facelift with dynamic LEDs so perhaps its even ILS+ ?
However i have noticed that sometimes it seem a bit almost sluggish. Not reacting as fast on oncoming traffic as i have seen it do many times.

Does anyone have any ideas on what could cause this intermittent sluggishness?

Glad you noticed that sluggish delays. HL are actually a complex system.
HL Modules check wheel speed with ESP and talk to one another.

Great question to which is the answer is your chassis needs a REBOOT.

It will help temporarily... likely 7 to 10 days.


Preliminary step us scan the whole chassis for a free comprehensive network overview.
Even "factory mint" modules can dysfunction. Given a chance they gang up and argue with one another creating data.

The decision of the logic of ILS for auto high beam OFF is from the camera seeing incoming traffic.
Keep glass/windshield clean and perhaps scan the camera's windshield heater strip/element at the front windshield, is it in good working order ?
My heater has gone kapoot, but I never use my Dynamic LED ILS for auto high beam anyway.

Here is the heater, it is called R50

That sounds plausible and by REBOOT you mean both batteries disconnected for a couple of hours?
Not sure i want to do that because i save my LONGtime stats for fuel consumption app.20000km right now

Your fuel stats may benefit or not with chassis reboot.

Over 20k.Km you already have a good idea what is fuel consumption like.

Fuel consumption is a complex topic with many variables. It's hard to make progress and still compare apple to apple while ECU maps are in transition.

Explore this link about VOLTAGE normalization. You'll find a link to REBOOT procedure included.
