The drivers rear is lower then the rest of the car, it raises when I raise the car but it’s constantly lower, I got a code in the module for the pump being to weak could that be it? Bad strut or bad?

I believe that you could have bad rear Air Spring(s), if the car is raised and one corner of the car is lower than the others, then that side is faulty. Also if the air pump was to weak, how could it raise the entire car? Just my observation.
Have your car scanned with either a Star Diagnostic Computer or Xentry computer to get at the route cause.

could be the rear level sensor as well starting to go, or its attached arm; which can affect one side only although there's only one sensor for the rear.
