Electric box hydraulic suspension pump

[Kees]

Hello, forummers.
I have a problem with the hydraulic pump. It starts with an error about the suspension.
Now i find out, that the problem is in the little black box in front of the pump. I need to open this one, because there is a connection not reliable inside.
I removed the four screws but something is holding the cap.
I put a picture in here, what seems the detail where it's holding it behind.
So how to open this?
Greetings,
Kees.

It's not designed to be opened, I believe it's a sealed unit Kees.

Hai,Marc.
I managed to open it!
You have to remove the tiny black cap, it's glued.
Then you see a tiny torx screw and if you remove the 4 torx on the corner then you can open it.
To get on the other side of the pcb you have to desolder the big lead contact.
I resolder al the components in the area of the outside connectors.
The pomp is now working fine, tomorrow i have to let out the air in the system and hope everything is fine.

Greetings,
Kees.

Hopefully that will resolve the issue, but make sure the unit is properly sealed again to prevent any moisture build up internally.

I only work on the electronic, not the pomp itself, and checked the condition of the carbon brushes.
