Overview
This is a narrow, owner-shared fix for a specific DPF regen error code on the 4044M, not a general maintenance overview. The owner explains the exhaust particulate filter's cleaning cycle valve froze up, triggering the warning light, and describes freeing the stuck bypass butterfly valve to resolve it without expensive repairs. Useful mainly for owners troubleshooting the same regen error code and flashing warning light.
Posted by an owner sharing a personal troubleshooting tip from their own 4044M, not a dealer or technician.
