Hello everyone. My 2011 E200 is having an issue with the auto high beam system. It keeps switching between low beam and high beam even when there’s no oncoming traffic, and goes back to low beam when it detects an oncoming vehicle, just like in the video i just uploaded on youtube:
And i scan fault code with xentry got a F with A40/11-Multifunction camera (mono)(MFK) Fault code: A3A813 - Der Ausgang für Seitenfensterheizung hat Funktionsstörung. There is an open circuit. A+S

Please help me
Try switching Xentry to English to help everyone read. I see your MFK does have a fault... MFK solderless connections
HELLA LED HL Module by Conti.
loose pins collection + heatsink paste
MFK and LED Modules need...
either replacement + coding
or a quick soldering job
Both are built to develop oxidized connections for transient faults.
These modules are super hightech besides mfg skipped the pin soldering step to make them not perfect.
The chips count on the LED Controller is out of this world, I counted more than 35 chips, not just discreet transistors.
It's a world-class German design.

Do your headlights use a control module or straight power from the SAM ??
