Hello, the ABS pump in my fiancée's car was damaged - there was constant air in the braking system. We bought a used one and took it to a workshop for assembly. After collecting the car, the brakes worked perfectly, but errors began to appear on the dashboard - all safety systems did not work.
We sent the old pump (the one that was originally installed) for regeneration - they replaced all the valves.
As you can guess, after installing the regenerated pump, there is still air in the system.
We are not giving up, we are looking for another one, but at the moment it is impossible to find one with the identical symbol.
Ours has the symbol G440.
Here's a question for the forum members, do you know whether it must be a pump with the same symbol?

P.S. I will only add that I also own an i30pd from the same year and with almost the same version of equipment and my pump has the symbol G421.

best greetings from Poland :)
