Suspension Stuck on high rear and low front

[femtiolappen]

Have try the bsi reset with no luck , firat I reassamble the rear sensor and start the car with no fuse! I see the car was set for highest level , press it down and after that I change the fuse , and the fuse not blow then I do the reset , but not working.

Thinking I Will fill Up trunk again with no batteri? Then connect battery and unload the car? Will it work?

Or open the lds system back of the car so it lower the car?

I disconect the + - for the pump , then try to high and low the car and fuse not blow , so its the pump that make fuse blow becouse it can not press more oil back.

The ventil for lower can not open manual? Or if I open the lds system in rear so it lows the car back to zero , than fill up oil and connect pump!

I opened the rear tube to the damper and emptied the oil so it fell together , screwed back and refilled new oil. Start the car and press button for hight but safe blow. So I think the ventil in the hydral block is stuck? Or is it the black box on top of it? I got 3 boxes from old cars maybe I try change it? Then it has to be make over for fit my car with lexia?

Ok, so you manually drained the rear suspension and when you tried to move it, the fuse blew?

Could you not lower the car by draining fluid then disconnect the fuse for the BHI and pump, thereby preventing it from opening any of the electrovalves?

Do you know why your pump keeps blowing the fuse?

The black box is the Suspension ECU and these are specific to each car and options - these will need coding if you change them and they must match your original part number - or you will create new problems.

Without Lexia on it to diagnose it properly, we will be guessing here... height corrector, hydraulic block, motor, ECU, ..... We really need some diagnostic data.

I will boking time with Citroën for lexia diagnose , they think it has to be depressurized

[GiveMeABreak]

Although you have manually depressurised the rear, a system wide depressurisation using the diagnostic tool will operate the electro valves, so will be able to check they are working properly. They will also be able to check for errors as part of the diagnostic.

Problem solved! It was the middle clock rear that stuck.

[GiveMeABreak]

Clock? Do you mean rear valve block?

[femtiolappen]

Yes

[EDC5]

So, have you had your valve block replaced? How much did that cost?

[femtiolappen]

I take it from one of my spare part c5 so it dont cost me nothing
