I thought you'd know that oneMy passenger side headlight makes that noise? Like its constantly trying to adjust? Why does it do that and does anyone know a fix?
It means the adjusting motor has a problem but it's difficult to say exactly what until it's examined. You'll find really long threads on the topic with all the info on how to fix.
I actually have the same problem but mine clears after about 5-10 secs.
Not sure why, but have also found that using the adjuster (on dash) can make it stop.
If you really do have a problem then it's best to take a look at it now before the motor chews itself up although I think it's a bumper off job
