Particulate Filter Soot Accumulation High

Understand P24B4, common causes, and the right TOPDON scanner to diagnose it.

High soot load — regen required soon.

Häufige Symptome

  • DPF warning
  • Reduced performance approaching

Typische Ursachen

  • Ignored moderate warning
  • Failed passive regen
  • City driving pattern

Welchen Scanner brauchen Sie?

Full-system scanner (engine, ABS, SRS, transmission, service resets)

Nutzen Sie Live-Daten und Freeze Frame, bevor Sie Teile tauschen. ABS-, SRS- und U-Codes erfordern meist einen Vollsystem-Scanner.

Diagnose-Tipps

  • Freeze Frame erfassen, wenn der Code erstmals gesetzt wird
  • Code erst nach Behebung der Ursache löschen
  • Auf verwandte pending codes prüfen
  • Batteriespannung über 12,4 V prüfen, bevor Sie Sensoren verdächtigen
