By taking the negative terminal off the battery and turning the ignition key on. Vehicle was still in limp mode with the DPF light on. After this I took a drive for about 25km keeping revs above 1800rpm. After 25km the turbo kicked in but the DPF light was still on. Did a code check using the accelerator sequence.

These are the steps for completing parked regeneration: Turn the engine on and get it up to temperature. Follow the prompts and press the information display button. Answer “Yes” to begin the process and exhaust positioning. After an operator regeneration has begun, the engine revs to 2000 rpm.

The DPF on the CM2350 (most 4th gen urea equipped trucks) and newer engines can last quite a long time (even for grocery getters), usually it's an issue elsewhere that isn't caught in time that gets them. The same setup is used in the Tier 4 final industrial engines, the DPF typically 4UoTr.
