Headlight range control system fault

Does anyone know what this fault is?

thanks

You'll need a diagnostic check to see if any fault codes flag up. Could be an issue with the ballast

Thanks Steve

You're welcome. If it is the ballast then this can be changed but might need to be coded in.

Range control is the level sensors on the front and rear lower control arms, easily damaged when working on suspension, I snapped mine so 3d printed a new arm from an A6 all-road air suspension sensor.

They can also go bad when the abs sensors break.
