In what modules do you read these code? A longer description of the code would be good since these codes are very generic.

[Alex polo]

Is this what you are after ?

[iichel]

yes. so it might be worthwhile to check the cable that goes to the abs sensor and check for any damage.

[Alex polo]

What is the best way to do that other than visually?

[Alex polo]

And on live data all the speeds match up as well

[iichel]

Yes either visually or with a multimeter. If that works out, in rarer cases the magnetic ring on the sensor is dirty or something is wrong with/at the ABS unit.

My thoughts were it is the abs pump module, but I will test the other things first, many thanks

[iichel]

On such a young car, it hardly ever is the module itself.

Can you check the wire connector and cable leads leading towards the sensor? Just back trace it a bit, see if there is some corrosion inside of the connector? Maybe damaged wire?
