 When investigating some "Suspension fault" messages, Lexia tells me that "sensor power supply is missing" for front height sensor, for rear height sensor, and for communication with built-in systems interface. All 3 faults are P05D2 which I can not find in the list.
Strangely Lexia does not report of any hydraulic pump fault, but the pump motor is not running.
So with all this "power supply" missing, I suspect the maxi fuse for the hydraulic pump motor needs to be inspected as a first step.

I have read through several very good related posts here, but I have not been able to find an exact instruction on how to get to that maxi fuse. And I did not find anything in the download section. I understand it is somewhere below the normal fuses. The photo shows how far I got (5 big connectors and 12V+ cable removed). What's next is not intuitive to me, and I don't want to break any plastic parts.

It would be great if someone can give a few hints on how to proceed towards the suspension maxi fuse.

Thank you!!!!!!

 I fiddled some more with the fuse box, and managed to lift out the upper layer to get access to the maxi fuses. To move the upper layer, there is a plastic flap (which cracked) located just above the yellow maxi fuse facing the front of the car, a similarly located flap facing the rear of the car, and finally a flap facing the left side of the car.

There was a blown orange 40 A maxi fuse in the empty spot in the photo. So I suppose that must be the one covering the suspension....

Has anyone come across a proper listing of what each maxi fuse is covering?

 Yes, one of the orange fuses is the fuse related to the suspension pump. If it was blown probably the pump is on it's way out.

Also, beware, I've read on a french forum that the cable that you disconnected is not a neutral but actually a live wire.

I don't think that cable is "Live" +............But.....it may be worthwhile checking it with a meter just in case?

Thank you eduardomaio! I just checked and you are absolutely right that the large cable connected in the fuse box is 12V + . I wouldn't have guessed so from it's appearance. Good to know!
