Particulate Filter Regeneration Incomplete

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

DPF regeneration started but did not complete successfully.

Veelvoorkomende symptomen

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

Typische oorzaken

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

Welke scanner heb je nodig?

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

Gebruik live data en freeze frame voordat je onderdelen vervangt. ABS-, SRS- en U-codes vereisen meestal een full-system scanner.

Diagnosetips

  • Leg freeze frame vast wanneer de code voor het eerst verschijnt
  • Wis de code pas na het oplossen van de oorzaak
  • Controleer op gerelateerde pending codes
  • Controleer of accuspanning boven 12,4 V is voordat je sensoren suspecteert

Can I diagnose P24AF with a basic code reader?
P24AF may set in the engine module, but related diagnostics often benefit from an enhanced or full-system scanner with live data and freeze frame.
Which TOPDON scanner do I need for P24AF?
Full-system scanner (engine, ABS, SRS, transmission, service resets) See recommended tools on this page.
Is it safe to drive with P24AF?
It depends on the code and symptoms. Flashing check engine lights and misfire codes should be addressed immediately. Consult a professional if unsure.
