Inconsistent Power Steering in BMW E60 525d 3.0disel After Maglock Regeneration and Pump Replacement

Hello to all forum members.

To start with, I light up the subject a bit, namely I had a gentle looseness on the maglock so I decided to give it back to regeneration, it was supposed to have a sprocket so I exchanged it
After re-mounting the maglock, I started the car, the power plant was operating without slack so I put the rest of the covers and when I left it turned out that there was no support. I went to make a coincidence, I made a car on the lift and when I left again I had support which after about 2 km passed again.
I connected the pressure gauge to the pump and showed 100 bar but when I increased the engine speed, the manometer showed 0 bar, after restarting the engine the gauge still shows 0 bar. So I gave away the pump for regeneration and the same situation, the support works at low revolutions, slightly gas (about 2 thousand revolutions) and there is no support again.
So I bought a used second pump, first dry without starting the engine, I shook the steering wheel, then started and I spent a long time flying tiny bubbles to the compensating tank so I turned the wheel for quite a long time and the engine was running for 20 minutes and I decided to increase it and it turned out alone, there is no support again.
I went to the BMW Dealership and they told me that it was a pump because it does not give signs of life, and when I told them that I had support going to them for some time, they said it could be a servotronic valve on the maglownica.
Any of you have any ideas? Because my hands are already falling

My car is a BMW E60 525d 3.0 disel, 2008. The only servotronic milling machine without an active steering wheel.

Added after 6 [minutes]:

Today I approached the subject again and after draining the pressure line from the pump flew all the liquid from the pump and reservoir, I connected back the wire and the pump came back to life again, of course after adding gas again stopped giving pressure but in the meantime I checked how this servotronic sensor works and seems to be ok, how do I shoot at a stop there is some 7 Volt and if I do not move the steering wheel it drops to zero, the sensor itself shows 8,2ohms in standby mode, so I think that he is fit.
I have even rinsed the whole system with a new liquid today to be sure that nothing blocks the filings, etc.

And in the mangle the valve is not there at times and he can freak something out

It seems to me that it is but after the regeneration and they say that it was tested and it was ok.
The overflow valve is also in the booster pump and as I gave back the regeneration pump twice, the guy says that the overflow valve was twice in the same position and did not bounce (he opened the open circuit).

I will say yes. Since the exchanged pump is only the mangle remains. Go to those from regeneration, say what and how the second pump, etc.

that's what I want to do but not to pull this mole again because it's a lot of work I ordered a third pump to be sure I might have such bad luck and hit the pump with the same fault.
If not, I am downloading the mangle and unfortunately I have to send them because they do not regenerate anywhere on the spot.

The liquid, of course, flooded the same as it was? Color and specification?
Sometimes it happens that the car has to go several minutes at idle without creating a steering wheel. Always on the table I connect servotronic to 10-12v from the power supply, without it even at 80 bars on the machine there will be no support and flow. Maybe such a coincidence with the pumps, if the third pump can not do it, I see such options. Damaged valve, clogged valve screen, or defective teflon on distributor / distributor between sections. As a last resort before disassembly of this unfortunate mangle, you could remove the servo valve if it is on top and check the sieve's condition if it is and if sometimes the sand left after blasting did not touch the channels everything will be visible at the valve needle, you could also connect the valve to some thin plus after the start-up and then check, but since everything worked before regeneration, I see no sense. The valve's power supply differential depends on the steering wheel position and the vehicle speed, depending on the vehicle from 0-14V. The version with an active steering wheel is an adaptation, I do not know how in the version without.

The same fluid, yet I called the ASO to make sure. The worst is the coincidence that the support was before regeneration and after regeneration two pumps the same problem ..
Already everything I tried, the car became even more like half an hour on idle and I was checking this sensor and unscrewing the snakes one by one whether liquid comes in but no longer disappears after the gasification.
Today, surprisingly, when I was driving without support at a sharp bend, I fell into big irregularities in the asphalt and the support came alive and squeezed it continuously for 3-4 rounds while turning the steering wheel and the pump did not turn off until I had to release to the lights and again the same.
So, I bet my bad luck with a pump, but it's only tomorrow that the pump will come.

I have Inpe and Disa at my disposal and there is no possibility of any adaptation here.

Wgl thanks for your interest

Well, mount the pump and not the gears for complaints. It is very rare for the plunger to break off and then the plunger moves without the skirting board during the turning process. But we can do it until you do not install another pump hopefully the pump will be over and you do not have to wake up the mage again

Ahh, unfortunately ...
Magiel on the ground, tomorrow flies to Lodz back.
The third pump and the same symptoms.
This is a simple system, the Pump - the magnet does not have any more, the hoses are not damaged, no leaks are broken or they are not, the sensor which is the only electrician in this system is also ok.
Unfortunately, the last part of the system was dead - the mangle.
After regeneration came painted and I think that maybe the paint flew into one of the holes in the magla and blocks some fluid flow and for this the pump turns off because the pressure is too high. I'd like to take the mangle off myself and see what and how, but I paid quite a lot for it, so let me do it.

I have already mastered the exchange of the pump, I recommend it

Hello, I have the same. The pump and the magglomeration after regeneration and after warming up the pump becomes ... 3 pumps were inserted, including one after regeneration. WHAT WAS THE REASON ??

Hello.
I have a similar problem.
I had a leak from the mangle and gave it up for regeneration. After mounting the mag, the valve on the pump hangs. I start the car and there is no pressure on the pump, after a slight tap on the pump, everything starts working properly until I turn the engine off and again. I bought a used pump checked at the booth in a regeneration workshop working ok. After mounting the car the pump behaves like the previous one.
Is it sense to buy another pump?
Tomorrow I am going to the workshop with a friend who has the same car and I will mount my "malfunctioning" pumps to his car and see what will happen.
Car 3 weeks in the workshop, I am asking for a quick response.

Hello, has anyone overcome this problem? We have the same situation after replacing the transmission, the valve in the pump is stuck.
greetings

I've dealt with the problem. As it happens with us mechanics because of their laziness and sloppiness I paid (Shit in the system). If the gearbox is going to be repaired, all hoses and tank must be removed and cleaned very thoroughly. The mechanic usually does not do this because it is an additional activity and he knows better. If there is any slight pollution, it falls during the work in the gap between the valve and the seat, which causes the valve to hang. if someone needs accurate information, I give the account number 501,665,256.
