Left High Beam Malfunction - Help

[mokleen]

Hello!
Long term member here.
I’ve had the car since nov 2021, it’s a 2022 MY and I have 20k miles on the odometer.


Welp, today I turn the car and I get hit with this error:

My gut tells me something electronically is just stuck or bugging out.

anyone know a way to essentially hard reset the vehicle?
Any known solutions?

thank you in advanced.

headlight control module needs to be replaced, not the little one for the DRL.

This one?

yeah, but IIRC it needs to be programmed to your car. you should still be under warranty, let the dealer take care of it?

Interesting, what the heck does this thing do if everything is still operating properly?

also, do I need to revert everything to stock before handing it over to the stealership?

Switch back to OEM ECU with stock flash/rom and tell them not to update it just in case.

Hopefully they don’t hassle you with a catless DP.

Did this ever get resolved? Hopped in the car today day and suddenly got warnings for turn signal, high beam, and low beam malfunction.
Seem to be in the same boat as you since they all seem to be operating properly
