Greetings, everybody. I will attempt to succinctly outline the narrative of my issue, providing a step-by-step account.
One month ago, the automobile had a malfunction with its gear changing mechanism and became immobilised in neutral position.
We brought the automobile to the service centre due to computer errors: P172E, U0418, P060A.
The hydraulics were error-free. I have purchased many components, including a release bearing, gear position sensors, a clutch sensor, and a solenoid.
The service centre began the automobile assembly process and found an issue where the hydraulic pump is only generating a pressure of 15 bar, far lower than the expected 40 bar. They are now unsure about the appropriate course of action to address this problem. They recommend replacing the hydraulic pump. I am sceptical of the notion that all components might malfunction simultaneously, since there were no prior issues with the pump. The service centre lacks the knowledge and expertise to determine the appropriate course of action, and I am uncertain about where to seek the source of the issue and the potential errors that may have occurred throughout the assembly process. The pump was removed and inspected visually for any indications of wear, but none were found. They speculate that some rubber bands or gaskets inside the object may have been deteriorated. However, I am unwilling to currently invest money in purchasing a new pump until it has been conclusively shown that the issue is with the pump itself.
Assist me, I implore you.
The hydraulic system, known as R-Tronic, operates at a low pressure of 15 bar.

How do they determine that the hydraulics unit itself is not defective?

Are you referring to a hydraulic pump? Or maybe you meant to refer to an actuator? There were no previous instances of mistakes related to hydraulics.

Can I conclude that if the ignition is turned on and the pump begins working, the hydraulic system must be sealed in neutral? If there is a malfunction with the actuator, the pump must operate continually and the hydraulic oil must be returned to the hydraulic tank. It signifies that there is a malfunction with the actuator.
Is there a method to determine if the issue is specifically with the actuator rather than the pump?

Based on the observations, it seems that the decrease in pressure is a result of an internal leak occurring in the actuator. The pump may malfunction due to a decrease in pressure in the actuator, which causes the pump to exert more effort. The pump will ultimately experience burnout due to the overburden.
