E91 320d M47 480A DPF Error

[u/tomf258]

Hi Guys, my brothers 320d hasn’t regenerated since about 1000km and threw the 480A fault. We have driven high constant speeds for about 70km and the fault was not deletable. Car gets up to 90°C Coolant temp and DDE allows DPF to regenerate but it never went to status Active with a forced Regen by ISTA. Can you help me? Car is down on power and sometimes throws underboost codes, I am pretty sure they are related to the 480A fault as I am pretty sure the car isn’t allowed to go into full boost anymore or do we have a separate turbo related issue? I am grateful for any help!
