Hello every one I’m new to this forum and am looking for help. I have a 2008 CLS550 after an oil change I got a malfunction light on my dash and at first the car would ride very stiff like if it was on a sport setting but none of the buttons were pressed so I continued to drive it. about three weeks later I went to fuel up and when getting back into my car I put the key in and it sounded like beating near my front wheel well I turned it on and it stopped it did it again at home and died out. The car now is without air and low. My question is if any one has had this occur to them and how might I solve it Tha k you for any and all help. My codes attached.

Sounds like the acceleration sensor failed, and then you killed your pump. Check your fuses, see if you can get the pump to run. Hot wire it if you have to. It's under the fender liner on the drivers side.
Usually it's a leak that kills the pump. It just runs itself to death. It could also be age. Check your wiring and plugs, Then replace some parts starting with the pump. Once the system is working again, clear the codes and see what comes back.
I ordered the pump . I had a bad shock awhile ago i replaced it. I’m assuming my pump just decided to give out now.
My question now would be what would cause my car to ride stiff I had the code on the picture that said the front left unit had open circuit. But would that be the shock itself or the acceleration sensor. Thanks for you guys time.
Hey guys so I installed the new pump but the car won’t rise. I checked all the fuses and replaced the relay but still nothing. I power the pump with 12v and it turns on but then resets my power probe.only codes right now are the ones that say that the front left valve has an open circuit. Could the shock cause the suspension to not rise? I saw on another thread that someone was having a similar issue with their car and they replaced and shock and repolarized the computer? Any ideas I don’t know what else I could check.
