Maybe , just maybe fixed!
How did I do it? Not got a clue!
After confirming that my TCG was fecked (see pic below), and Mike sent me his to try, I connected it all up and still the car wouldn't run right ,still smokey and very sluggish. Rather strangely though when driving I was getting no boost at all until it hit 3000rpm and then the turbo kicked in and off I went hurtling towards a road end at 1000 mph lol.
So I decided to do some testing again with the vac gauge.
I took off the vac pipe going to turbo and connected the vac gauge to the outport of the TCG (everything else connected as it should be) , and the readings were all to ****. It was showing 25hg at startup which was fine but when I revved the engine the vac went down to about 10hg (ok) but stid there when I let the revs drop to idle again (should have went back to 25 hg) The first video shows this happening.
I shut the engine off and started a new video and it seemed to clear itself and behaved as it should do (see second video) . Try as I might I couldn't get it to stick again at 10 hg.
So I took it for another drive and it went like a damn rocket! Full boost in every gear. Strange but true!
Anyway all seems to be OK for the moment so heres hoping it stays that way.
Thanks to everyone who tried to help , and a special big thanks to Outnumbered who I reckon deserves an MBE for his services to the Volvo community lol

I have this vague memory of someone else posting something like this ages ago, I can't even remember if it was on this forum.
As far as I remember, a few squirts of WD40 down the pipe to the vanes freed them off and then it ran fine....

I know on mine I have electronic control of the vanes but you have vacuum control so it might make sense. Mike will pop along soon and give us the benefit of his brilliance and thoughts on this idea....

I wonder if the vanes on your turbo have been stuck and that's what destroyed your TCG? All the messing with guages etc have made them free off?

I reckon this is definatley worth a try . It would be a 10 minute job and cost nothing more than a can of spray . Saves all the hassle of taking turbos off and stripping and cleaning them.
The only thing that worries me is the risk of it going up in flames , since all these sprays are flammable and the turbo does get rather hot .
Maybe someone will be brave (silly) enough to try it lol and let us know what happens.
