I doubt the AHI nozzle/7th injector is clogged if the regen went that far before failing, and there's just so many reasons as to why. The PM sensor could be faulting, DPF differential pressure sensor, the DPF itself might be too far gone, there's no telling without being able to diag the truck itself. It's complicated, which is the biggest downfall of the emissions system; it keeps owners from repairing their own truck more often than not, and makes the dealerships and OEM a LOT of money while they throw parts at it because none of their techs are properly equipped and trained to do anything else. Not like their managers would let them spend extra time to diag properly, Volvo Uptime is all about speed you know!

I remember back when i used PTT. We would open the window to check for updates before using it.  Maybe you have updates waiting and then you can force the re-gen again.. i think its a PTT issue. Did the MIL light go out, or at leaste the after treatment codes go away?

Well there was some patches,  tried  it again  today   after a little  bit at 99% same error. All it's missing it seems is cool down message, soot level  reset and all seems fine. I also changed 7th injector.  I'm gonna call diesel laptops  see if it's them or I need to go to a dealer
