Bi-Xenon Leveling/Aiming issue
 

My headlights are aiming somewhat lower than before and I had noticed that they appeared to stop auto adjusting while driving. At startup, they do lower and then return to their normal position, but just not as high as they used to be. So, the mechanism isn't broken. I did a scan with the BMW Scanner 1.4.0 software but didn't find any errors. Can one of the leveling sensor simply went bad, but the scanner not detect it? If the leveling sensors are good, is it possible to just do a leveling "reset" for our Bi-Xenon headlights somehow? Any input would greatly be appreciated. Thanks.

Check the level sensor connecting links first. If there are no codes, sensors and links look to be correctly connected and the lights do the initial setup, you can always adjust the aim on the headlights.
