Recently, I noticed that the headlight (xenon) up/down feature (self leveling) during start of the car not seem working. Headlight beam did not go up & down, it just stayed at one level. Any suggestion what to look for ?

Thanks,

No blinking, solid green.

Thanks.

Is it supposed to go up/down. Upon startup, mine go from left to right.

If it has an issue the light should be blinking. Mine has been blinking for about a year. Troubleshooting has been a headache and I gave up.

If yours is not blinking then it doesn't see an issue with the modules.

Yes, it is supposed to do that during startup, kind of a self check. This is the auto leveling feature and this is a common feature now in most of the high end cars.

If that is the case then what else could go wrong and cause auto leveling not working during start up ?

Thanks.

Not sure. But on mine, if I have the headlights "ON" vs "AUTO", they don't steer with the front wheels. Otherwise, they do the up/down when starting, then side-side.

The motors or broken guides

The system is checking itself when starting. If it sees something wrong it will start flashing on the selector panel
