Laguna Passenger Wishbone Sensor

Hi,



My Lag 2 has a broken arm on the front passenger side wishbone sensor which I believe is used in conjunction with the rear axle sensor for levelling the headlights lights.



Can anyone tell me how this arm is supposed to connect? Maybe I can fashion a repair.



Also, are either of these sensors used as part of the ESP system? I get an ESP fault but my diagnostic thing didn't arrive yet to see exactly why.



Thanks.
