connected the car to INPA, read all modules, all error codes, the shadow memory... nothing significant - no power spikes from the alt, no dips...

however, i think i found a victim of the incident - the rain sensor... it is not coming online, and the headlights turn on with a 3 second delay - i turn the engine on, and the lights turn on 3 seconds later, both the exteriors and the illumination inside... the light still come on... the vertical adjustment is working but the horizontal adjustment was not working... so, i thought the AHL module, the adaptive headlights is fried...

put that module in manual mode, the lights adjust left and right... but not automatic...

since i ran out of time, i did not do further troubleshooting but on my list is to check the rain/light sensor fuses, check other fuses related to the LCM and most importantly, read the saved PDFs of the errors that i pulled - i just skimmed through them...

other than that, the lighting operates as designed minus the adaptive portion. wasn't raining today, did not test the auto wipers function and was too lazy to pour bottle of water over the windshield... lol... too cold...
