Hi, new here.

Cannot perform a forced DPF regen. When I try, it comes up finalised straight away.
Symptoms are no power (40kph max)
Engine is at normal operating temperature.
Any ideas?

Cheers
Dyson

What other fault codes did it have when you cleared them most recently? ;)

I believe P2458 is indicative of the ECU refusing to do a regeneration due to other problems, for example a wonky reading from one of the sensors.

There was only the one engine code, plus the ABS and trans codes. Intermittent speed sensor codes but watching live data the speed sensors appear to be working.
Could the other codes influence the P2458?
Cheers

1 Fault Found:
16848 - Diesel Particulate Filter
P2458 00 [173] - Regeneration Duration
Have done a Bluechem DPF clean and the differential pressure has come down a bit.
Have tested the DPF pressure sensor and it appears to be working fine.
In tank fuel pump works
Checked and replaced the fuel filter - no unleaded fuel in system
P2458 fault will not clear, even with ignition on engine off
No acceleration/no power.
Only 90,000 km's so not expecting manifold to be carboned up and blocked as yet (I could be wrong though)
Thanks for your help

Problem solved.
Went into adaptions, particle filter initialisation and saw soot levels still being recorded at 40g even though DPF had been cleaned and was no longer a restriction.
Changed value manually to 5g soot accumulation, cleared fault code, started engine and hooray, engine power restored and check engine light staying off.
Cheers
