That's the sensitive screw here below.

The only faulty code I have is a low pressure, obviously, P1773. The strange thing is that right now, I have no "selespeed failure" alarm on the dashboard.
And yes, there is fluid in the system. When the pump is running, and the screw out, oil is coming from the hole.

 

[NikoG]

Yes it is, close to the max mark. When the system was working "fine", the reservoir was more empty than it is now. It's like no oil is going to the accumulator. Which is logical if the circuit is open somewhere, the pressure is too low to push the gas in the accumulator.
Something should close the circuit at some point, and it's not happening here.

Agree. I'm going to check the resistance for the EVs. I know the big ones should be around 2.5 Ohm and the small ones 5.1 Ohm. Hopefully one of them is dead...

Ok, STOP!

Before you go any further may I suggest the following -

1/ Leave the car overnight with the hood up, this is to allow the system to depressurise and dump most of the fluid back into the reservoir. Do not open drivers door or put key in
the ignition till the next step the following morning.

2/ Take the cap off the Selespeed reservoir - it should be a good amount ABOVE the max mark, if not fill it it so that it is close to the bottom of the neck of the filler tube

3/ Open the drivers door, the pump should run for a few seconds, wait till it stops. Place the key in the ignition and turn to MAR, the pump should run again for a few more
seconds, wait till it stops. Now check the level in the Reservoir, it should have dropped significantly and now be close to the maximum mark on the Selespeed reservoir dipstick.
If it hasn't dropped then the issue is that the pump motor may be running but the pump section itself is not pumping any fluid.

When you say you replaced the selespeed pump did you replace it with a brand new one of one from a wreckers?

Do this before anything else and get back to me.

Hi.
I did everything you said.
Fluid level dropped to the max mark, but the pump keeps running and the pressure measured on MES is still 0.000 bar.
The pump is brand new, Magnetti Marelli.

 

[NikoG]

Yes the whole pump. And the accumulator was also brand new, Magnetti Marelli not oem copy.

 

[NikoG]

Yes it's plugged in, and wiring is fine. There's really no pressure in the actuator.

 

[NikoG]

That's exactly what is happening. I can't see if there are any microscopic metal debris or if something is damaged in that bleeding hole, but obviously the screw is not sealing the circuit properly. From outside, it looks like it is, but inside I don't know. And as it's shown on the 3D model for the hydraulic circuit, if the screw doesn't seal the circuit the accumulator is bypassed and there cannot be any pressure in the actuator.
