It seems to me that the Hi-Pressure Turbo isn't kicking in - and I can hear a "whoosh" of air (a bit like somebody pursing their lips and exhaling) when I press the throttle to invoke it...
Hooking up my fault code reader, I get a "P00BD" error code, which apparently means "Mass or Volume Air Flow 'A' Circuit Range/Performance - Air Flow Too High", although that's just a generic OBD-II description...
When I got home I cleared the fault code, took the car out again and it drove normally for a couple of miles but then the error message and "whooshing" noise reappeared...
Other than that, everything else appears normal.
So my guess is that the Mass Air Flow has developed a fault (or is simply clogged up?) which has led to a turbo pipe splitting. Does that sound feasible?

Many thanks in advance!

No not feasable at all , you have a turbo hose split , most likely one of the hoses going to/from the intercooler , they tend to rub on the subframe when expanded under pressure .
