GC4P Manual headlight leveling problem

[hittolaine]

I read few topics regarding similar problems, but couldn't find the exact same problem so I made a new topic, sorry for my English in before.

I have a 2015 grand C4 Picasso with d5s 25w xenon's, my headlight adjustment works quite randomly, sometimes the lights go up when I start the car, sometimes stop at the middle of the height adjustment and sometimes just stay at low and don't light the road pretty much at all.

Anyone have any clue what could be the problem here, they always seem to work in pair, so if one stays down so does the other, and if one works the other one works too.

Also one time when I had power on, but not the car, and I walked outside they were moving even though power was on for a long time already, I didn't notice if they were going up or down, but heard the leveling motor going on.

I appreciate any help, thanks in advance!

If you have directional headlights the system self-tests on activation of the lights and will move to check operation. During use, if there is any problem with the levelling system or the directional lighting, the default backup mode is to revert to the static dipped position with loss of directional movement. Usually accompanied by a message of a flashing dipped beam warning lamp.

So best to have it checked out to ascertain what the issue is.

The directional headlights work normally in all situations, no message or flashing dipped beam warning lamp.
