Had the wierdest of drives into work this morning.
Everything was well until I accelerated onto a roundabout and the disco just revved a little then chocked up, lift off throttle and lovely tickover. Had to limp onto the works carpark until I had a chance to look at it.
When I got a chance at lunchtime it seemed to rev up ok so I put it down to a gremlin, probably electrical and due to the heavy rain the hight before.
However, when I came to leave later in the day it started ok and began the journey home ok but then went all chocked up again.
I rummaged about and eventually found a rather squashy turbo hose onto the intercooler.
I took the hose off and then drove home at max 40mph.
I now need a new hose - strangely it appears to be the internal lining of the hose has delaminated.

Hope you've now found the problem.
Hose delamination isn't that uncommon, sadly.

Interesting failure though.
As its the turbo side I'd have thought it would be ok but the delamination must be causing it to balloon in the airflow and block it.
Anyway I've proper bodged it for work tomorrow, I have put an inner sleeve in it made from an old top hose.
Took it out and its running great.
One thing struck me though, is my disco going to perform better with the new hose?
It must have been restricting the airflow for a while before finally causing a complete blockage.
 
+1 for genuine rubber or high quality silicone.
I had silicones but finally changed back to original ones. In my case the silicons were slightly oily on the outside which probably coused by the poor quality of hose material which let the oil mist penetrate though the wall of the hoses. Even I changed the hose clamps to really high quality ones (you need stronger ones anyway for silicons) the oil mist was still there. For me it also means that pressure also lost.
