Driver side Of my XJL 2011 is sitting lower then the passenger. Is there any trouble shooting tips I can be doing to try to activate the driver side air suspension?

 

antdavis1911, unless you have the SDD software, there is no real test that you can do per se. The one thing that I would try though is to start the car and then load like 300-500 pounds of stuff (2 of your friends?) into the rear seat/trunk. This should cause the rear of the car to droop and this will engage the air leveling system. That should bring up the left rear corner. This will also let you hear if there is an air leak. But, odds are, you are looking at some sort of air leak. the question is whether it is in the lines or in the air spring itself. That is where the SDD software would command the system to test out the car and you can then get some results. If you live near Washington DC, I would say for you to come down to me and we can hook up the computer and test it out. I just got my SDD computer up and running. If you are not near me, maybe a member near you will offer something like what I am offering.

 

Thanks for the information... I wished I lied in DC tight now but unfortunately I live in Kentucky. I’ll take your advice though.
