DPF is only checked on mot as to being present 

[Jimbob]

Should also add on the 1st set of data....7000 miles into an oil change, so would beleive the cars interpretation of remaining oil life, so presume DPF life also accurateish.

at 7000 miles im starting to think about doing my oil change!  but the car claims to be happy with it even if im not!

[Kevin Wood]

Engine Oil Change Warning (DPF Regenerations)   Inactive
Remaining DPF Regenerations   67%

I interpret that to be the percentage of DPF regenerations before it warns for an oil change, not DPF life. I assume each DPF regen potentially contaminates the oil with fuel, so it's a factor in the oil change calculation.

For what it's worth, one of my vans was running with no fluid (Peugeot so fluid dpf, not dry like yours) for well over 25k, without my knowledge, due to damage. I have just replaced the reservoir, pump and fluid bag, had a chat with the Pug version of Tech 2 and all is good even though the ECU was saying it was toast!

A forced regen is worth trying IMO. Removal is not as cheap as I first thought (I was looking into it as an option on said van).

Another possibility that I have seen banded about (I accept no credit/responsibility for this, just seen online from a few different forum sources) is to take it off and pressure wash it, then let it dry before refitting.

Check the usual's:

EGR state
MAP sensor
DPF pressure sensor pipe (I have now replaced mine with rubber from the metal part right to the sensor as it split slightly further up....and it only ever flagged an occasional exhaust temperature sensor code)

Mine is on 148k miles and the DPF is regenerating about every 800 miles or so, when new it was about every 1000miles but, they do slowly fill with ash.

Alternative is a visit and we pop it off, cut the top off , remove internals, seam weld back together and refit ready for programming out by a-n-other.

Any MOT Testers care to say how they are checked?  to my knowledge removal is smashing the innards out and a reprog rather than replaing with plain pipe?

Visual check to make sure its there(or looks like it is ) and a normal diesel test which it'll piss through with or without its innards

AFAIK it's only a smoke test.

The only way I would have diesel car, and I must admit the mpg makes one attractive, is if it was on lease. No worries about DPF problems then.

remove it and get the car re mapped.

They cant check it if they cant see it or are too stupid enough which most of them are to see that its been removed.

If its done properly very unlikely youd get a fail. same stuff coming out the exhuast with ot without it.

and for completeness  : (Im not sure 26% satuartion in 145km is right....unless dpf not fully regenning?)

your DPF  need forced regen. as atm its blocked thats why you have so many regen try recently
what diagnostic tool you use ?

[Jimbob]

I've a Chinese op. Com. Sure it can do it. I'll get it hot and have a go
