Opel Mokka p2458 Regeneration time DPF car does not start

Hello, Use your help.. Opel Mokka 243174 tk has p2458 as a mistake and cannot be deleted. In short: I tried to regenerate in the stand, took longer than an hour and still didn’t make it. Then the car wanted to drive, but went out after about 100 meters and since then starts off briefly or not at all. DPF for several hundreds of km new AGR exhaust gas temperature sensor in September 24 new. Look forward to your opinions Lg
