Experiencing Intermittent Power Steering Failure on 2003 Opel Astra G Z14xe - Insights?

Hello, I have an Opel 1.4 Z14XE 2003 engine and I have trouble with power steering. The power steering works normally after starting the engine for a few minutes, then stops completely after a few minutes. After driving without assistance, it works again for a few minutes and then it works for a longer time, sometimes it only turns off for a moment during a longer ride. I checked the voltage during the proper operation of the support and it is 14.6V as the support does not work, it is also 14.6V. Power steering is TRW version 2 without ribs. Nothing happens when you move the steering wheel quickly. During the power steering operation, you cannot hear it, it seems that the bearings do not make noise. What may be the reason for the temporary failure of the power steering. Cold February in the pump or something from the ECU. I checked the computer and there are no errors in the assistance, there is an error P1482 but sometimes it appears and disappears (the air conditioning is working properly) turns on and off the key light. Has anyone had a similar case or what could be the reason for such support work?
Regards Goblins

Error P1482 is caused in most cases by the ECU (driver).
Poor contact (usually with a warm engine) causes the light to light up sporadically.
The contact responsible for support is right next door and probably not in the best condition either.

Thank you for your answer. From what you write, it is about the plug / socket in the ECU or there was damage inside the ECU. The version of my Opel is without a fan controller in the wheel arch (there is one ECU from the engine and the fan). Which pin in the ECU corresponds to the support, I will check it.

This is what the driver looks like inside (corrected contacts visible).

Thanks for the photo and help. I had a few problems with the ECU fan, fuel pump, air conditioning sensor and sold the whole socket again from 2 years ago. I soldered the socket where the fan is. Is there power steering on the same socket ?? on which pin should I check ??

Which socket did you solder?
X71 contact 15 is the power steering.
X71 contact 31 (no connection and error P1482 pops up).

Thank you very much for providing the pins that are responsible for the errors and my problems. I sold the socket from the fan, the AC pressure sensor and the fuel pump, the same socket (is the same socket from the power steering), maybe February has let go. From what you write, there is no point in removing the power steering pump because it is an ECU. You may have all the pinologies of the driver for the Z14XE 2003 (version without the fan driver) because sometimes I also have trouble with the Lambda P0130 and P0136 probe (but I do not know if it is not the fault of the fyrkoczący silencer

This driver has 128 pins, so it's a bit of a laborious task to describe them all.
It's best to see for yourself on the diagram (they are also available here on the electrode).

Thank you for the answer on Monday, I will do the driver, then on Tuesday I will probably write how the repair went. Are the pins provided by you in the hybrid driver tai as I have or for a driver that does not support fans (my driver controls the fans and motor) is this driver from the photo
best regards

Looks the same. This is probably a DELCO Multec controller. Only on the basis of the diagram you can tell which pin controls the fans. My driver is for the Z16SE engine.
One more thing.
Repairs can only be undertaken with appropriate experience. This is a very delicate job.
You can find a video on how to go about it on the net.
for example here
or
and in Russian

I added one more picture with marked pins (post # 4).
X71 contact 15 is the power steering.
X71 contacts 24, 31, 36 fan control.

Thank you for your answer and drawing. Yesterday I soldered and I think everything is fine, I will have to go on a longer route and check if everything is well after heating. I soldered a few points from the fan, I soldered the point green marked. I also send a photo of the soldered entire connector. February is darker for 2 years ago. Thank you very much for your help.

Cool. Soldering the entire connector is really a lot of work. Did you do it yourself? The worst thing is to remove the sticky gel, because at the same time still functioning connections can be damaged very quickly (they break off very quickly).

It even turned out nice as you write a lot of work, but you shouldn't break it that often. I soldered myself as I wrote from 2 years ago (you can see darker February on the left) and now the split and the fan are supported, but the wires are not broken, but February is gone. When soldering, I did it so that I cut one wire, then soldered the next one, so as not to make a mistake because there are unused pins and you can make a mistake. The original cables are very soft and break easily. I sold all the pins to new wires because I had enough of the ECU every few months because some pin broke.
