Hi I am having all sorts of problems with my car. Basically the car runs great for a time, this can be 20 miles or 500 miles and then will suddenly loose power sometimes the dpf light will come on aswell as the engine management light and what looks light a traction control light. The car has been serviced recently at Mazda its done 77,000 miles its a 2006 Mazda6 diesel and has been back and forth to the Mazda Dealer about 4 times with no apparent fault found until now. I have a diagnostic report saying.
Description - P2458
Diesel particulate filter regeneration duration
Possible causes:-
If p242f is detected, please recover the failure descrided on P242F prior to P2458.
-Soot accumulation(the condition that allows you to conduct the manual regeneration for DPF with diagnostic tester or DPF switch)
-exaust pressure sensor failure
-pcm internal failure

status - ff
no status available for this DTC

Next Sheet

Diesel particulate filter restriction- ash accumulation
Possible cause :-

I have spoken again to Mazda and they are saying they THINK it needs 4 new injectors at £600 each plus fitting I have now removed the car form Mazda as I really can't afford to go spending that kind of money on it at the moment. But after looking into info found on the forums I don't know if the info they have given me is correct. Any help or advice would be great or if you have experianced similar problems how did you resolve them.

Dude, find another forum. Can't you hear the crickets chirping on this 14 month old/unanswered post?
