Focus 1.6Tdci -09 Regeneration problem

[rehtori74]

Hey,

I have problem with regeneration. Forscan shows fault P2458 and engine regeneration every 10-20km cycle.

Regeneration temperature is about 550-600c° highway speed(120kmh) and that takes time about 10min. dpf differential pressure sensor value is ~12Kpa (highway speed)

I trye stand still regeneration, but did not go through.

dpf filter has been changed to 15000km then.

Need help.

Tanks!

I have the same problem.
I have cleaned the DPF with JLM cleaning fluids. Replaced cracked DPF pressure hoses. Ordered a new pressure sensor.
The mileage is very bad, and the motoroil is being filled with diesel.
It all started with 3 bad injectors.
EGR is blocked.

Best regards
