I own a Ford C-MAX 1.6TDCI, engine G8DC
A few months ago, the turbo and DPF have been replaced.
Car is running fine, however when I connect it to Forscan (with engine running) it shows:
===PCM DTC P2458-21===
Code: P2458 - Diesel Particulate Filter Regeneration Duration
Additional Fault Symptom:
- Signal is Above Maximum Threshold
- Previously Set DTC - Not Present at Time of Request
- Malfunction Indicator Lamp is Off for this DTC
I see no other DTC codes.
Question: does the line "previously set DTC" mean that there were problems with regeneration, but it is now OK?
I would expect that if there is still something wrong, the DTC would still be active?
