cl 600 abc suspension failure

In the passed two weeks my suspension blew 3 lines and one regulator for the r-front strut.
Could my pump be going bad and over pressurizing the system. It moans at around 2,000 rpm. But is fine at all other rpms.

Isn't the ABC system pressure kept at the correct level by a pressure regulator system. This looks like the Pressure supply valve unit (52) and the ABC pressure sensor (B4/5).

It has absolutely nothing to do with suspension and I just banned him. He was advertising on many threads but no more.

As to your suspension the pumps are known to go bad but in this case I feel you got unlucky and a lot of smaller parts went wrong at the same, or almost, the same time. Wait out and see if anything else happens first.

This system runs at about 200bar. So I would not say that it is over pressurizing. But since you did blow some hoses which means most of the fluid leaked out the pump maybe going south also. Not sure how far you drove the car once the hoses blew but with no fluid in the pump it can be smoked with in 45 secs. Hope this helps and good luck.
