You need to do the Basic Settings procedure laid out in the Ross Tech Wiki.

I’m getting the exact same fault codes done the basic setting procedure esp light went off then come back after drive same codes. So I’m thinking of changing the steering sensor at the moment haven’t got the time but that’s my next thing to do.

I would check the output from and the centre point reading of the sensor before replacing it, the tracking being set incorrectly can cause the fault code.
