Hi

If the vts terminal would not allow extra time to be added it would have been for one of two reasons as i understand it.

1)it has had an mot test pass registered on line & has more than a month remaining

2)A replacement/duplicate new style cert has been issued in place of an old style cert that has more than a month remaining.

The system has no provision (for vts)to "dig" for info regarding old style mot result info.

Hope this helps.
