WinEEM4 service tool DPF regeneration provides the means to activate the DPF regeneration functionality. The graph in the middle of the page plots the temperatures which are most relevant to DPF regeneration process. Several other relevant values are displayed in the right side of the page.
When test is activated by user, engine speed will be set automatically to ~1500 rpm. Engine Management System then starts controlled DPF regeneration process. The process takes about 30-50 minutes, time may vary due to environmental conditions and DPF soot load level. During DPF regeneration engine noise level may vary. Process progress will be shown to user. After DPF regeneration engine will return to low idle. Let engine cool down on low idle minimum of 2 minutes before shutdown.
