Hello I have a 2000 CL500 with the hydraulic ABC system. I had a leading shock and the day I got my hands on a new one the pressure line went. I ordered the line and changed the shock in the meantime but now the front passenger side which is the one that I replaced is sinking all the way down. Is it supposed to do that bc there's no fluid going to it bc all the fkuis came out when the line popped. My question is after I replace the pressure line what are all of my next steps? Any and all info deeply appreciated. BTW I'm diy

What happened after the line failed?
Did you keep driving?
What warning messages did you get on the dash?
Did the car maintain normal ride height at each corner?
Did you try changing the ride height?
Is there any fluid left in the ABC reservoir?

After the line failed all the hydraulic fluid came out. The reservoir is empty. Before it failed the car was rising up and down now its just down. I didn't drive it. I parked it and replaced the front right shock that was leaking. The warning light says don't drive. And now the shock that I replaced is sagging. When I replace the line will it raise up like normal?

Sorry, no. The ABC pump does not self-prime. Even if you fill the reservoir to the brim, it will not pump. What you have to do it pressurize the reservoir with one or two PSI air, to push the oil into the pump, then it will be primed.

Can you please tell me in detail the steps I need to take after I replace the line? I replaced the leaking shock now what's everything I need to do after I replace the pressure line so that it'll be back to normal?

Use an air compressor or other air source to pressurize the abc reservoir
