the sensors we re cleaned 2 weeks ago.. but the fault apeared after only 6 days after cleaning them...... The car is now at a citroen expert in garage..... first thing he noticed.... was the green fluid LHM...used for older Citroen ....and not the orange LDS..... and he said that this may have distroyed everything inside...power steering ...suspension pump.... but he will check this later today. The fault is that the suspension gets blocked...and stiff. the car gets a bit lower than the normal driving position and i can t put it back up. I mean it shows me on the dash board the signal "opening in progress" like the car would go up. but in reality it is not moving. The position now ...and for the last 2 days.... is the lowest posible... the one that you can use it for loading something in the boot. But normally, that position switches back to normal when car i starts moving. Always when i was opening the car i could hear the sound of the suspension pump leveling the car to the normal driving position. Now we i'm opening it the pump does nothing , and the car stays in the lowest position. And any pot holes on the road or speed bumps ...i fell them very rough ...like the car has no suspension at all.
