DPF regeneration not possible

Hello Together, Nox and Adblue were deactivated on the vehicle. Recently, the errors P2463 and P246C. DPF full and regeneration were not possible. DPF was cleaned. DPF was re-educated. After that, manual regeneration was started with Diagbox. Couldn’t be achieved with the message out of exhaust heat. Did the regeneration work with nox and adblue? Nox was ordered and adblue is then reactivated in the hope that regeneration will work again. Vehicle has SCR Kat and a hole between KAT and DPF.
