I just replaced all the airbags on my car front and rear last week
after the job was done the car was getting low overnight only in the rear but will go to normal after i stated the car
yesterday morning i saw that only the drivers side is lowered the other three are fine
so the rear does not drop anymore but only the drivers side
on the dashboard i have Malfunction

it show this when i try to raise the car


and this while i drive

the suspensions are brand new all 4 of them
now i wonder what should effect to lower the frond drivers side only ???
i do have a Mercedes Dealer appointment but i wanted to know if there is a need for a reset the system or if there is a sensor who is causing this problem for me
Thank You
