Turbo not alive in 3.0d?
It hadn't made any odd noises ever there was from day 1 a slight whistling sound that never got louder in the 14 years I have had her, 2 days ago I just noticed it was just not delivering any punch, car still hits 110kph and over fine but not as fast.... No recent work done that I can see caused this like air filter being put in wrong or on wrong causing air intake sensor to give wrong reading and non fire up of turbo...and have no idea if the CATs are blocked as one fella said was the issue with his power loss....dunno just stumped....the accumulator hoses seem fine.... Worry is can i drive it in this state safely? i read doing so that it can cause engine damage?

Without turbo/boost it will work like naturally aspirated engine. So it will work but with less power. Like said earlier you likely have a cracked exhaust manifold which can explain most of the symptoms. You can do a rough check on turbo vacuum actuation just by checking if the rod on vacuum solenoid pulls the guide vanes closed when engine is started. (This can be seen without taking anything apart from above with a flashlight.)

Much appreciated clavourion, time to research the terminology you used guide vanes rod etc and where from above i can see what you refer to, sorry am a novice most diy i have done is remove readd front bumper
Ps must have cracked manifold as on cold start i observed smoke in area...just odd that the timing of power loss has not coincided with when i noticed the smell in cabin of fumes/due to the manifold issue

Here you can clearly see vacuum bell and rod on the other end (below).
From above. (Red plug where the boost pipe is connected.)

This from a different engine with slightly different turbo but you can get a picture how the rod is pulled by vacuum when engine is started.

Picture tells a 1000words, apologies though what is the rod i am looking for movement in, the black rod with elbow type end on it? I can see the manifold too connected thanks for insight...i hope my cracked one hasnt released any bits into turbo...

The cracks in the exhaust manifold get slowly worse until they bleed off so much exhaust gas pressure the turbo doesn't spool up properly.
You have a known fault, related to the exhaust manifold - fix that first, then diagnose any remaining turbo issue (which I doubt you'll need to do).

About once a year The issue comes up where the vacuum accumulator (not sure the precise name) fails. The symptom is that you can have power for a spurt but if you climb a hill you'll run out of power.
Vacuum leak in plenty of places can cause the problem
