Hello,
A 2005 Polo 9n came to my service with a power steering problem. Sometimes the power steering stops working, an error pops up 00816 - Power Steering Sensor (G250) 30-00 - Open or Short to Plus but only when the wheels are turned to the left or right to the maximum. The previous service replaced the power steering pump and the sensor on the rack, but it did not improve the situation.

I do not know what the original pump numbers should be, I got a second one for this car also with the ending AB and there is the same problem.

Is the pump number wrong, is there a problem with some calibration or is the rack damaged?

Thank you for your help, best regards

edit:
I forgot to add. I have a new type of sensor (3pin) on the rack without a cable - with a socket

Theoretically it is the correct pump but used electrics are a fools game, we would use a TRW JER162 exchange unit.

Thanks,
I also try not to install used things like this, but this is how it came from the previous workshop.
