Did as you suggested and plugged into the OBD2, before stopping the engine, to see if there were any codes registering. Absolutely still no Codes/Errors found. It as usual, after leaving the car stand for a while and restarting, still had the Yellow Warning lights and messages on the dashboard, AND again disappeared once I drove approximately 100 - 150 yards.
Very confused, any other ideas?
