UPDATE: I have discovered the problem.... I am an Idiot!!!! Basically after the Global Test I left it on Built-in systems Interface rather than switching it to Engine Management ECU... so it is all back to happy again.
As always, any advice, ideas or suggestions are absolutely welcomed even if this includes checking if I am an idiot!
Apologies for anytime wasted.
Have a good day.
