Thank you for the link.
I have run my own diagnostic system, but it is ISS, not Vida Dice. The list of faults was quite impressive.
Interestingly, a high turbo pressure was indicated, amongst everything else.
It is my gut feeling that the issue is a general communications fault rather than a specific mechanical issue being reported.
I have included my report here, but having read many posts on this subject (various random errors, anti-skid warning and others), it seems very much that there has to be a root cause.
Fortunately I now have a good mechanic, and my background is electronics and specifically communication systems. It would be ever so nice if we can discover the underlying issue that is causing so many of us to have issues.
This is going to take a bit of thinking about.....
I may have to invest in a Vida Dice system myself to really get to the bottom of this ...
