Power loss, boost after 2600rpm

Hey guys!

I have a 2008 mod V50, 1.6 diesel which one day about a month got a loss of power, and had it since.. it has around 176k on the trip.

From 1400-2600 rpm there is "no power" (like limp mode), but after 2600rpm it boost as normally, but the turbo is a bit more whiny then before.

About two weeks before the power loss came, the car went in limp mode and my local volvo dealer said that the DPF was clogged because it hadn't been able to start the regeneration. They deleted the code and the car went like normal again, and recommended to drive it around 3000 rpm for 30 minutes so the car could start the regeneration it self. It seemed okay after this, until it got the powerloss.

I've changed the MAF sensor og checked the EGR valve. I were gonna blank it, but it was already blanked. I removed the blanking-plate and then I also got rid of the fault code which was on the EGR (445D)

I have no fault codes now, but the car still have the power loss.. Any good ideas?
