My Disco has just started to idle roughly and these codes are popping up.
I clear them and they return.
Any suggestions on how to tackle this.
Thanks

Get the battery tested.

I agree, first check the voltage with the engine running under full load, a/c, head lights and stereo.
Should be between 13.6 and 14.4 volts.
