    i have the same car,,, heard about the ABS rings "snapping" might be worth taking the wheels off and having a look, whilst rotating the cv joints.

    If it was speed sensors it'd tell you its speed sensors.

    Looking at your fault codes, theres some comms issues between the ABS, ECU and Cluster...

    Could be a failing ABS module, or corrosion in the wiring somewhere?
