Symptom
DPF light on; Request for "Parked Regen."
Diagnosis & fix steps
DPF Soot Load - High.
LOGIC: The pressure differential across the DPF shows it is nearly plugged with soot.
ACTION: 1. Perform a Parked Manual Regen.
2. If it fails, check the "Doser" (7th injector) for clogging.
FIX: Perform Manual Regen; clean/replace DPF filter if it won't burn off.
Red Seal field insights
If the machine keeps asking for regens every 4-5 hours, your 7th injector (fuel doser) is likely plugged. It won't throw a "doser" code, just a "soot load" code.
