VW Passat 2004 1.8T ABS & ESP Issue

Hello.

A VW Passat 2004 1.8T.
The ESP and ABS is not working, and the warning light are on.

The codes i found:

65535 Internal Control Module Memory Error
I do not really know what this code is?

01316 - ABS Control Module: No Signal/Communication
Is this code most likely to be problem with wiring or the module it self?

01425 - Yaw Rate Sensor (G202) Signal Wire
Is it most likely to be a sensor or wire problem. The code say wire, but i do not know how to test it.

18256 Please check DTC Memory of Engine Controller

01420 - High Pressure Switch Valve 1 for Electronic Stability Program
This switch is located inside the ABS module to prevent to high pressure or?

Is this a common fault, with some common solutions?

Thanks and best regards from Sweden.
