Well guys and gals, there has been a development since i last posted.
The entire reset was done, and it appeared to be ok, until last week when the auto hold suddenly came on twice in a few minutes.
My daughter was obviously distressed again, as she adores the car.
However, we have since agreed a deal to put the car back to the place we bought it, and have traded it in for a different brand.
She is gutted as I mentioned above, she loved the car.
Anyway, appreciate all the replies and advice, but the bottom line was that I personally felt that the car was unsafe to be driven and due to the fact I work away a lot, i am hoping that the tearful calls are now in the past.
Thanks again for all the help that you gave, much appreciated.
