Do you have another problem with the car.
c1131 lamp is burning and there is only error.
What is the car's chassis number

[cronosik]

only c1131, everything else is ok. and the error lights up only from time to time, when it's off all systems (VDC, hillholder...) works perfect.
VIN:ZAR93900007027086

on some alfa romeo 159's the pressure sensor was external to the main abs block , the sensor looks similar to an oil pressure switch with a hexagonal 24mm i think outer , this is probably your problem .

to double check , delete the error then disconnect the electrical connector plug (2 wires) the same error should ocur.

to replace remove and refit then run the pump motor in the abs ecu actuator test .

Let me know how you get on
