2012 Mitsubishi L200 dpf/ cylinder
Year: 2012
Variant: Warrior
Categories:
Electrics, ECU, Warnings & Lights
I have had a previous problem with the dpf light coming on and was in limp mode streight away and had Mitsubishi assist come and try to do a regeneration at my home to no avail. It was taken to Mitsubishi garage where they changed it on the warranty. I advised them that I do motorway journeys every day so this issue shouldn't have arisen! 2 months later the light has come on again and been taken into the garage where they tried to regen and couldn't so like deeper and did s compression test and are now saying it needs a small motor new dpf and sensors etc at a ball part figure of £9000 they won't cover me on the warranty as i recently missed a service and they say it's because of that this has occurred which I do not believe! I spoke to someone Fromm the AA and they agreed with me. I need to know where I stand and how the dpf regen or sensors not working would damage the piston rings/ engine

Not really sure on the re-gen parameters that have to be met on this before auto regeneration occurs.
And I'm not sure what help I can be anyway.
There's a lot on the web about failed DPF's
and my own personal experience is failure is caused by oil contamination.
Contamination is usually caused by combustion gasses getting in contact with the oil.
That's what makes it black.
oil itself doesn't breakdown as commonly believed,
only gets contaminated.
From memory your engine has external injectors,
I'll check at work on Monday,
So I'm left with the conclusion that combustion blow past the rings is doing the nasty.
So your root cause is the low compression and blow past on the rings/bore.
as to what caused this and when it happened?
My only suggestion is try a website called "honest John"
and follow the prompts.
They can be more inclined to the legal stuff.
