ok so i have this headlight field vision error coming up on the display, and the lights have gone really low.
any clue on how to solve this problem ?

Check both the front nearside and the rear nearside suspension arms.  probable that the small link arm on the position sensor has come adrift.  Push back in place meantime, pending replacement either from a dealer or a breaker on here....

Check the picture.

There is a locating arm with ball and socket joints at either end which connect the sensor on the arm to the bodywork.  Its the movement of this arm which tells the lights at which level to adjust to.

If the arm pops out the joint it sends wrong signals.

Replace the arm onto the ball and see what happens when you operate the lights.....   

As Hotel21 has already said, it will most probably be the arm has popped off pulling the end out of the sensor. If so, just push it back on, and if the end has 'spread' slightly making it a little less of a tight fit you may have to fasten it on with a cable tie or two. Try not to be too heavy handed with the sensor body as the casing will have become brittle with age, especially around the mounting bolt holes
