2010 4.4 tdv8 boost problems

Click image to enlarge

Hi
Attached I hope is a photo of my fault codes am getting which is causing restricted performance.

Am trying to work out what activator it is meaning has gone wrong . I have checked the one at the bottom of the radiator and it's free and no damage to the wires and am seen it moving .
The turbo on the passenger side . Left hand . Can't see him realy to see if it moves . The pipe and wire appears to be ok .

The drives one am check it and the linkage is free . But you can't move the activator arm . And am run her up and it realy dosnt move much at all . Seams to be half way and just moves enough to take the slack if that .

So is this the drivers side turbo activator that's playing up .


When driving it drives ok then you can boost her and she sets off as per norm. But when she's light load she trips into restricted performance. So thats making Me think the drivers turbo . Think that the small one if am right .

So can someone point me hopfully in the right direction. So am no firing the parts cannon.

My fault appears in the low revs and boost like just after top of a hill and the revs is under 1500 to 1000 rpm. I can find no damage on the pipes to the bypass valve . And am seen it open and close . So am thinking the bypass is OK and she dosnt go into restricted performance when you drive her hard with high boost . So I lean more and more to the primary turbo.
