Thanks in advance

Although the car behaved differently enough to convince me it wasn't a leak in one of the four intake rubbers, it did eventually turn out to be a leak in one of the four intake rubbers.

The inconsistent behaviour, etc. convinced me it must have been something more serious but I can only put it down to the awful software that ahendles the faults and reports a multitude of ever changing error numbers, offers zero acceleration or full acceleration, etc.

Easier thing is to whip the four rubbers off and check them.

It soon cleared itself as if by magic
