Cl500 hissing sound, and trunk problem
I'm starting restoring
my 2003 Cl500, and i need to figure out a couple of things.
the first issue is hissing sound from the front of a car, it started after replacing the pulsation dampener, i've read about it here at the forum, that the valve needs to be repaired. And now my question is, is it the front valve? Back of the car goes low after a couple of nights, and i thought that the rear valve needs to be repaired

Next thing is the hydraulic trunk lid issue. I have replaced the cylinders a year ago and it was opening normally, and now it goes up only in the right side, like before replacing the cylinders, and it needs a little pull to open. Also when it closes, the right side goes lower than the left side, can it be regulated somehow? I have replaced the oil in the pump, and don't know what could i do more.
Please help

Still need an advice about the hissing from the front of the car, and rear going down. If anyone has any ideas, please help.
