Mitsubishi Pajero Sport Carbon Cleaning Malaysia — DPF
Pajero Sport 4N15 diesel: carbon management centres on the DPF (Diesel Particulate Filter), not intake valve deposits. City-only driving prevents the DPF from completing passive regeneration (requires sustained speeds above 80 km/h to burn off accumulated soot). If the DPF warning light illuminates, take the vehicle on a 30+ minute highway run at 90–110 km/h to trigger active regeneration. Forced regen can also be performed via MUT-III scan tool at a workshop. EGR valve carbon buildup is a separate concern at 100,000+ km — contributes to rough idle and hesitation.
