I need to send in my Power Steering Module for repair, but I have a few questions first. My vehicle is a 2014 Audi A4 (European Market), Right Hand Drive . Recently, after driving through water, the steering ceased to function. I've had the mechanical components of the rack serviced and am now considering sending the control unit to you for servicing.
However, I want to ensure that other components, such as the motor position sensor on the rack, are not faulty before proceeding with the control unit repairs. Could you advise if there is a way to test this component?
Here are the details of the control unit:
Part Numbers: 8K0.909.144.B, 8K0.909.144.E
SW: 506
I have attached photos of the part and the OBD scan codes for your reference.
