ABC Suspension lowers when driving and engine shutt off
Hello,
I have a 02 CL500 V8, and I'm hoping someone can help me narrow down how to solve my issue. Several weeks ago, I had two solenoids go bad on the rear ABC valve block, so I replaced the entire valve block, along with replacing the accumulators. When I drive 1/4 block, the rear lowers but levels out when I press on the breaks, and the front suspension raises a little higher as well. The rear also lowers when I shut the engine off, I hear a humming noise (like an electric switch, maybe), and the rear suspension is slowly lowering itself until it's sitting on the tires (the noise stops afterward). What could cause the rear suspension to lower this way? Thanks for your helpful suggestions/advice.
