Not quite the same problem as you, but my VTS would cut out at high rpm and in diagbox showed VVT as "active" but the live data graph was a flat line. I have had the cam belt changed and although the timing for it was correct, the belt was slack as the tensioner was not working. It now seems to be ok.
