Mercedes cls 320 2006 wont lift

[Beadsvalet]

Hi everyone I have a cls 320 2006. I bought it recently and it had the suspension workshop warning. The car worked as it should but would lower down on the rear of left a few days. Then just before I went on a long trip the car dropped on the rear and said stop to low. I have then looked around and found relay wasn’t clicking and pump dead. Plus the pipe going to the filter was ripped. I got a new pipe. New pump. New relay. Checked fuses. But no matter what I do the car won’t rise. It doesn’t seem to be sending power to the pump for some reason:/ Iv plugged scanner in and wiped codes. Comes back saying system leak. When I go on the scanner and make it test each side you hear a click but no rise. The car is currently slammed. I have tried jacking car up to ride height but nothing. Any help be great
