Hi Mike

Sorry yes! And all came back ok
Has the vehicle been driven with a diagnostic tool connected to monitor live data?

Live data run has been done!

Pressed send to soon no faults found
With all of the test that has been done, the way this happens and the symptoms, is all consistent with a fault with the ECU and the communication with the vehicle. I understand that the ECU has been checked however some internal faults do not show under normal testing.

The ecu was sent to an official test centre
If the ECU was eliminated then the main engine harness has to be checked next for a short or back feed.
