Another problem with the Volvo still getting the vvt coming up as a fault the car is running slow extremely feels like a 1ltr could the vvt solenoid make the car run like this?

Depends what you are used to...they are not light cars but a '99 T5 should be quick enough, no VVT would reduce power but not by that much
Fuel consumption OK?
Its hugly down in power bud its like the turbo isn't working atal if I put my foot down you can feel the turbo trying it might burst into life or nothing atal car sounds like its down in power to
invest in a boost gauge and pod dude and check your pressure. Easy way to check it and you also get a boost gauge into the bargain

The girls a stunner!
I have a boost gauge mate boost is just over 6bar
I think you mean psi (14.5 psi to a bar) 6 psi is well down on the standard T5 where you should be around 10psi of boost in standard form, if you mean 0.6 bar this is also a little low but sounds not too far off the mark...
Sorry yes 0.6 bar
VVT only affects the power over 4-4,500 rpm, and not by that much. Although .6 bar is a bit low, it shouldn't feel gutless.
Must be something else which isn't throwing a code just drove it about and it was running with power again turbo quite noisey well loud air realeasing noise. When car was losing power I couldn't hear turbo noise it felt like I was driving against 300mph wind starting at 0mph in 5th gear!
Sounds like a split boost pipe to me.

850 tdi - sorely missed.
I fully agree ^^^^
If your getting a 'loud air releasing noise' as you put it, then you clearly have a boost leak.
Check your hoses have not come disconnected first where the jubilee clips are.
Second, check all your hoses and squeeze them. Your feeling for a split in the pipe.
Thirdly, if all above ok, then your likely to have a split IC. (More common than you think) look for oil residue on the back of the IC, at the sides, This is the give away!
Otherwise, it's your Turbo.
Good luck!

Hoses are fine new samco ones fitted a couple of months ago.
What is the ic? Intercooler? I only have the air releasing noise if car is running with power if no power I hear no air leak
Even if they were new it's still possible a jubilee has come loose, personally I'd still check them all.

IC = Intercooler.
Just because you've fitted new Samco hoses, as Martin says, doesn't mean they're not split. I can tell you from experience that silicone hoses are notorious for coming off especially when using those crappy wide band clamps! The clamps don't bite into the hose as a normal jubilee does and they will pop off if the clamp is not tight enough.
What do you mean....'with power, if no power no leak'? Do you mean you only get air rushing noise when under boost ie your foot to the floor accelerating?

When the car is running with power is when I can hear the air escaping when I put my foot down
When the car is running as fast as a 50cc moped I can't hear air escaping
I had really low power when I first got my R. Would not boost at all. Changed all pipes relating to vacuum. Turned out to be a blocked cat. Exhaust was not allowing the turbo to spool up. Have you had a misfire at any time?

I think he means sometimes the car runs well and other times its as slow as a 50cc moped. Not that he's driving slow.
So when it is running and the turbo is spooling he is getting the air release sound.
And when its running really bad and slow he's not getting the noise
