Help needed - ‘restricted performance’

[Hawc]

All, have just been hit with the red triangle of ‘restricted performance’ whilst en route with family and trailer in tow, to tip of Cape York. Currently just south of Townsville. Have read fault codes using GAP IID tool and cannot clear faults. Appreciate any assistance on how to clear fault or repair issue. Land Rover mechanics not available today.
Thanks in anticipation. Andrew

My suggestion would be check the mass airflow sensors…A and B circuits (B is closer to front of the vehicle)…Powerfull UK (a YouTube channel have a video on this)

Swap the 2 MAFs then see if the fault stays as B or is now A.
Ensure that you have pending faults enabled in your IIDtool to see all faults.
