Having numerous DPF issues with my 2015 Peugeot 308 SW 1.6 BlueHdi basically it's done near on 140k miles and I do mainly short journeys these days so it's getting blocked and the soot must be building up as well. I've tried on car cleaning a couple of times and doing a regen which helps but the faults come back after a couple of days. A replacement DPF isn't really viable financially but have been quoted £150 for a DPF delete reprogram if I physically remove the BPF gubbins.
Putting the moral \ legal considerations aside has anyone had one done and how did they fair at MOT time? Is the smoke test likely to catch me out?

Also should add that Peugeot use a combined SCR\DPF housing and that to remove the DPF element I'd have to cut open the housing and reweld. I'm aware this may throw up an issue for the tester but I'd have to do this anyway to give the filter a proper clean so is likely to be an issue even if I don't go down the delete route
DPF delete is illegal and if seen by an MOT tester will not pass like that.
Of course you could have thought about it beforehand & as you do lots of short journeys you shouldn't have bought a diseasel.
On top of that you will likely never get anywhere near the published MPG figures as they use a LOT more fuel for the first several minutes until warmed up, which is when you are then turning it off.

The fact the DPF is missing is an automatic fail per section 8.2.2.1 of the above link.
At that age/mileage you'll be far better served by taking it off, soaking it in DPF cleaner and washing it out.
This video shows roughly how that works, https://www.youtube.com/watch?v=GnkBOtrcukI
And this one compares assorted cleaning products, https://www.youtube.com/watch?v=Zw-EAc_Lpv8 and has other videos showing how to clean it out. I used the Wynn's off car cleaner, which worked for me, though there are many alternatives.
One note of caution is that PSA vehicles will trigger a DPF fault at some point past 100k, regardless of the state of the DPF. Cleaning like above is a good time to tell the car it has had a new DPF fitted.

te to vehicles, and then it's the customer that has to suffer them later on.I’m sure some will judge me here, but here’s my experience of doing it, which is what you’re after.
Deleted the DPF on a van I used occasionally, not as a workhorse. I tried several cleans and it just clogged up again within a few hundred miles. Delete was done and it was remapped at the same time to add a bit more power as well as sort out any fuelling issues. The van went a like a rocket afterwards. 190bhp in an effectively empty shell is surprisingly quick. I didn’t have any issues at MOT time, although I did make a point of driving through a lot of mud to make sure the bottom of the van full of crud and didn’t have any shiny new weld marks on there. It didn’t smoke after I had it done either, although there was no emissions test back when I had it done, not sure if there is one now. Downsides were that it kept throwing up an amber EML as it was looking for a sensor that was no longer there. That was easily cleared with an OBDII reader, but the light would come back every 15 times I started it. Ideally they should have deleted that code when they remapped it, but for some reason couldn’t. I didn’t pay much attention to fuel usage as it when it was used it was for longer motorway / dual carriageway runs.
This was about 8 years ago and ran the van to around 2021 before selling it. Was honest with the buyer about the delete and gave him the OBDII reader so he could clear the light when he needed to. It was a £10 eBay special.

If the dpf is repeatedly clogging it will be due to a fault, removing/ deleting won’t fix the underlying fault.
It is likely that optical particle measurement will be added to the mot to catch dpf deleted vehicles in the next couple of years. At that point you will be looking to restore your dpf and delete the map.
Things to check will be glow plugs, these are needed for regeneration, measure with a meter.
Thermostat- does the car get fully up to temperature?
Differential pressure sensor - are the pipes intact and not blocked , does the reading change on your obd reader when you rev it?
General air leaks in the induction system - get a smoke test done.
As stated above, some cars just state ‘full’ after a given mileage as the ash content calculation will have reached the limit. Off car cleaning and dpf reset in software to tell the car its new will fix that.

There is little worse than driving behind a diesel which has had its emissions hardware removed. Especially when on a motorbike. These are the cars government should be focussing on getting off the roads. Anything pre DPF should also be taxed into oblivion.
I have a Euro 5 D4 V40. Do you know why I have no DPF issues? Because I bought the car for the job. 200-400 mile regular work trips.
The wife does 20 miles a day. Petrol XC40.
Saying that, I am currently eyeing up 2 stroke KTMs………

I know this may come as a shock to you but circumstances do change for some people. When I bought the car I had a 50mile each way commute but changed jobs and now work 1.5miles away, I either walk to work or use a petrol Citroen C1 i bought for the purpose, 308 is now mainly used for tip runs etc I have a Euro 5 D4 V40.

But hey when it comes to buying another car I'll drop you a message and you can check your crystal ball, tarot, astrological charts to see what the future holds for me so I can make a more informed choice
