C5 hydractive 3 electrical issue

[tomassk8]

I have come to terms with the fact that the car is not as soft as I thought it should be. I have never sat in another c5 x7, but any other car is comparable, if not better, than the C5 on minor bumps. Because of this I replaced all the spheres, all the chassis parts and it still didn't help. Last week my electronic handbrake broke and for some inexplicable reason the car went soft like never before... It didn't take long and I'm driving hard again. I would like to recommend to throw away the solenoids and test it only which would be adequate to the solenoids so that the car does not give me an error. Can I simply measure the resistance of the solenoid and use a resistor of the same value between Terminals + and - on the BHI?? I suspect that the Ecu is passing current to the solenoid even though everything appears to be OK in the Diabox. The instruction manual with Diodes, which is here, is for hydractiv 2 where the mode is opposite (voltage on the solenoid during soft ride)

What is the difference between pump MXG a Cinch? (you can see on top of plastic electronic part)

Cinch is the name of the manufacturer of the Pump.

Hello everybody, I'm new here and facing a problem similar to this one.
I'm reading alla long the forum but I've not come to a clear idea of what and how to check the anomalies.

Here is what I'm experiencing: I bought my c5 x7 two years ago and I remember it to be insanely soft and the sport mode having no effect at all.
By the time the suspension became very harsh, particularly the rear ones.
When the vehicle is at still they appear to be soft like every other car whilst the front ones are very stiff. When riding the very opposite happens: the front ones are a bit harsh but the rear ones are definitely stuck hard.
I've tried to pull off the rear stiffness EV connector and voilà! All of a sudden everything returns to be comfortable.

If I understand the x7 suspension electrical behavior then the EV gets excited when stiffness is required and this matches with it being soft when unplugged.
The EV must be electrically and mechanically efficient, otherwise the system would not become stiff when the connector is plugged in.
I've tried to measure the voltage on the connector but the circuit is open so it could be meaningless, anyhow I always see 0V with the car is parked (engine on).
I'll be trying to do the diode mod on the BHi connector in order to monitor them when riding.

What puzzles me is that it seems that the ECU is trying to push the rear EV in stiff mode just when you start riding but it is the front axle that seems to be stuck in stiff mode all the time, regardless of the car status.

No one in my area seems to know and understand the Citroen hydraulics and the best I'v got was the suggestion of buying new ammos which I think is a big waste of money with no effect at all.

Thank to anyone who may help.
