Absolutely! DPF's and the labour involved are not cheap! As I said earlier - you could just keep on driving - but the soot build up may not just affect the cooler, but also beyond - the LPEGR valve, turbo, intercooler etc. So, perhaps early intervention is desirable. First step would be to get an expert to undo the outlet of the DPF and have a qualified inspection to confirm. If the decision is made to go ahead, then you would also have to inspect the cooler for soot content as it would be easy and relatively cheap to replace at the same time.yes i realised i hadn't updated template 0 but was on a road trip with my kids... with do so before the next for sure! If i'm in a position to do so, i will give it a good boot during the next regen and see if i can spike the temps with the throttle - i think @theoneandonly suggested this might be contributory a while ago.
With reference to repair / recondition, one company has seen the boroscope footage - they advised that perhaps the cement cracking between the bricks is the only issue and suggested it 'could' be a reasonably easy fix. they also advised that the LPEGR cooler port is the only real difference between my DPF and a number of others which are more easily available (reconditioned, mine are rare as rocking horse sh*t apparently) so what they can sometimes do is use another as a donor part - take the innards from it and place it in the case of mine - so i get my original case back with a warranty'd filter matrix. prices roughly as follows:
clean / repair cement £200ish
replace innards or OEM reconditioned £1400ish
New OEM £3500ish
I'll be doing some more investigations and phone calls on this during the week!
you can see why the push to understand everything before putting a new one on

yes i think this is the road i am going down - and you'll recall the start of all of this was needing a new LP EGR! i have already sourced a mechanic who is willing to have the vehicle with him for a week or so while the dpf is sent away - obviously commercial garages dont want this hassle they just want the turnover of easy jobs. He has already also agreed in concept to examine the egr cooler while the DPF is away - i havent priced this yet, nor have i absorbed the thread on the P0401 codes etc - I understand there is a 'tea strainer' inside where the blockage occurs but do you have any thoughts on cleaning versus replacement of this?
@Fredastaire would be best placed to answer this question for you as he has significant experience with the cleaning vs replacement of the LPEGR cooler.

@Dancingbear @deejays, I'm still here , on my second cooler change however not sure how long before it blocks again.
.
I started the long 90 pages + post just like everyone else by changing the HP EGR because the fault code (incorrectly) says so. I cleaned my HP with caustic soda solution made from crystals / hot water; I've also cleaned my first cooler which is ready for refitting. The caustic takes only minutes to dissolve the soot. I tywrapped a rubber glove on the cooler inlet pipe so I could fill from the outlet end.

The O ring from Fiat cost circa £18!! I've checked with my hydraulic shop nearby and he's given me the UK spec and sold me spare ones

Dancing Bear, I note you've located a DPF repair company, I would be pleased if you can give me their details, a PM would be fine.

I'm still wondering what to do, I don't fancy much the idea of software deleting as UK mot regs may outlaw it. I don't want to loose my v32 Fiat software to a 'tuner' reprogram. To have my DPF rebuilt sounds a right way to go.
