Auto headlight level light on dash.

[tomistoogood]

Hello guys,
since removing the front bumper and needing to disconnect the lights after now putting it all back together ive found that there is a level light on the dash with two arrows and a exclamation mark, i know there is a sensor on the passenger side arm, ive had this off and checked for damage and seems okay, is there another sensor anywhere or shall i just replace this one?
Thanks.

Best to get it scanned, rather than guess.

As above, get it scanned.
