You need to recode the LCM (light control module)
This is a known fault.
I work in dealer i answer this with knowlegde
If i got the job i would recode the light control module.
The lcm is the control unit that controls the lights. It is linked to the suspension because of the auto leveling headlights.
You asked an expert and i answered
If you go to dealer just ask them to recode the the LCM it only takes 10 minutes so should not cost much. If you go with just the fault they will charge you loads of money for diagnosic time. I know this because i would do the same.
