very true Landshark, I do appreciate your comment, there is loads to check and yes, im in the process of acquiring a vida system, so I can do some investigation, but do take all comments and suggestions on board, .....but do like to price up the suggestions at the same time. ive a feeling it could be as simple as a pressure sensor, where is that located as would like to try the connector plug on it as a first check, could need cleaning.
