Headlight Auto Level

[qcumberhd]

Hi, my headlight auto level light came on a little while ago. Is it a common thing that it could be the auto level black box? http://www.ecstuning.com/Audi-C5_A6-...ight/ES370285/ Or is there a better chance that it is something else?

Almost always a broken sensor. There are 2, one on both front and rear beams too look at.

is there a way to tell which one is bad?

Most of the time the plastic arm connecting the sensor to the control arm that breaks and causes the failure.
