Headlight range control system fault

[Rahim k]

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.

I got my level sensors changed but I think it’s more to do with coding. If coding don't work then its definitely the ballast . Im taking it to the garage to get it checked.

hi guys,

I just went to the garage and they gave me this reading from diagnostics.

The garage told me possible the whole headlight need to be changed.

You may need check the wiring and the connectors for water ingress, not easy because it's tight. 

You could possibly get a picture of the inside by removing the road wheel, arch liner access and disconnecting the ignitor.

Or remove the unit from the car to check it.

I put it on water that's got in somehow and is bridging the contacts.

Get the part number and buy a second hand headlight to see if that cures the problem.
