ABC left side drop
First of all thank you all for the help on the forum.
After servicing the valve block, flush of system with new filter, replacement of the blue flex hose and left front accumulator everything was working great. Each of the services performed another issue would happen. Drove the car a couple hundred miles without issue. Yesterday I drove the car hard, ran great and when i turned off the engine the left side of the car dropped within one minute. Start the car and the car raises to normal height and the height adjustment works fine. ABC malfunction comes on with one code and will go away with a restart. No fluid on the floor. Reservoir remains full. Is this a simple bleed of the system? The ABC system has been haunting me. Solve one problem and another pops up.

I found the problem. One of the hydraulic lines started to leak at a connection, the line I replaced. Very slight leak not enough for oil not to hit the floor. Made sure the fitting was clean and tightened fitting. Maybe a thimble full of fluid leaked. Everything working great. It hard to believe how sensitive the system is.

The hydraulic line coming out of the blue valve body connecting point located driver side front. The whole right side would go down, not just the front. It is working fine now.
