2010 BMW 5 Series, 520D, F10 - Malfunctions in Low-Beams upon bulb replacement

[Matt865]

Greetings to everyone, I possess a 2010 BMW 5 Series, model 520D, F10. I recently replaced my headlight bulbs with new H7 LED bulbs. Bulbs of comparable strength [200W/50000LM/6500K]. Subsequently, I get the following two errors on my dashboard:

Left Low-Beam Headlight Malfunction
Right Low-Beam Headlight Malfunction


Upon examination with an OBD2 reader, I receive:

Errors 800F2E/800F2F: Left/Right Low-Beam Headlight, Malfunction or Reignition Failure for Xenon

When I activate my light, both errors vanish. Each time I initiate the process, I consistently encounter these errors until I activate the lights.

Do you have any insights regarding the errors I am encountering? What is the reason for the mention of "Xenon" in the error?

Approximately three weeks ago, while replacing the bulbs, I inadvertently cleaned the connector with Standard WD-40 instead of the appropriate Contact Cleaner. Could this be a rationale?

This is a general code description for headlight bulb malfunction. whether halogen or xenon is installed.

The headlight bulbs will require load resistors when transitioning from halogen to LED, as the removed bulbs likely had components to ensure the bulb check system functioned properly.

As previously stated by guyskin, it is a cold check that occurs when the vehicle is initially activated, during which it inspects for malfunctioning bulbs.
LEDs consume less power, leading the system to erroneously conclude that the bulb has malfunctioned.
I deactivated the cold check feature on one of my vehicles using my diagnostic scanner, and there is a setting in the iDrive for the F20 model. Indeed, that is how I organised things in that vehicle.
