VW Golf MK5 Fog Light Error

But I noticed a second thing. When I turn on the high beam, the Xenon beam jumps and after about 3-5 seconds it drops to normal level and the bulb error appears. VCDS says that the reflector motor is faulty. But the weird thing is that when I start moving left and right, the Xenon goes down and goes back to normal level. The reflector motor works. Or is it the work of other motors to go down? Is it faulty or do I need to do some adaptation or something?
And my ambient light/light sensor opens or shorts to ground. Or something like that. Not sure if it is connected. The right Xenon works fine.

Erase fault codes, check motor reflector, if everything is OK without error codes, you can do basic setup in VCDS.
Probably motor reflector is damaged. Often the problem is in headlights in VAG group.

After the fault has been reset, the indicator on the instrument panel will go out until the next time it is turned on. The high beam and Xenon are switched on, and after 3-5 seconds the warning returns. And then the Xenon light drops to its normal height. How can I check if it's the motor, the reflector or something with the control unit? Is there a way to troubleshoot?
