Servodierction pump

Hello, I write to see if someone can guide me in the following.
I have a Chrysler Voyager 2.0 (1999).
I am in France.
The starter key is blocked.
I call assistance and tell him to repair him and make a general revision of the vehicle.
The € 800 invoice includes hydraulic oil and belt change among other things.
I'm going to Paris. When parking, I can't, the address is extremely hard (underway if it works well).
I take it to a workshop.
They tell me that the Servo bomb is gripped.


Question: The pump would only be folded if I had no oil, if it were not adequate or if there was a leak. correct?

Can then be due to the manipulation they did in the first workshop?
Is it normal for a service pump to be flu?

Thanks in advance for taking advantage of your experience.

Dear friend, I do not associate the block key with the change of straps and hydraulic oil, in any case the direction pumps are grouped due to lack of oil but this grouping is serious since all the internal pieces of this are scratched, weaning (Azulous) and normally they are tranco and nothing serves does not know if this is your case.
You explain that when parking it gets hard and runs it works well, therefore it gives me the impression that there must be dirt that the overpressure valve sometimes keeps and the pressure that must reach the box is in By Pass.
Unfortunately it seems that your vehicle is already disarmed.
I would like to know the end of the corduroy of your vehicle and I hope it does not result in very high costs.
Greetings and luck.
