Particulate Filter Regeneration Incomplete

Understand P24AF, common causes, and the right TOPDON scanner to diagnose it.

DPF regeneration started but did not complete successfully.

Häufige Symptome

  • Soot level still high after regen attempt
  • Check engine light

Typische Ursachen

  • Stopped mid-regen by driver
  • Fault aborted regen
  • Insufficient fuel dosing
  • EGT too low during regen

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
