Once the Steering Assist (44) has been coded with the code '11250' (in your case), you may also have to do the basic setting of steering angle sensor (G85) in the ABS unit (03), which is a different procedure.

Something similar will be for your diagnostic tool.

Keep in mind that it is possible that the faults will disappear once you exit communication with the ABS module and perform a new ignition cycle.

Must be:
6R0423156C

The item 12H0037 'according to Autodoc' should be compatible, but the pump you installed (6Q0423156AB) is installed on previous models (Polo 9N3, Ibiza 6L, ...).

Looks like you're absolutely right ciclo:

I'd suggest to get the right 6R0 C pump
