I came here looking to post a new thread on DPFs and found this one.
I have to agree with hpc3 100% of the way, "if you cant afford service, buy petrol"
And windy1603 is also 100% correct, you may struggle getting a car through the emission test since in 2018 the authorities tightened the regulations on the exhaust gas analysers to catch people who had removed their dpf from the system. I spoke to them, email, in 2017 as they were looking for ways to catch the cheats.
The MOT test changed on 20 May 2018, with new defect types, stricter rules for diesel car emissions, and some vehicles over 40 years old becoming exempt.

I also hugely dislike the sellers of EGR blanking plates, it just promotes poor maintenance and creates all those vehicles you see emitting huge amounts of black smoke as they accelerate.
But enough of what I like and dislike, the real problem is how does one get their Peugeot dpf replaced for a reasonable price.
I've waited over 2 weeks for my local garage to re-open during this lock down period, I urgently need to establish from whom did they purchase the new DPF fitted to my car October 2018 for £287 fitted.
In 2018, the price for a non badge dpf from Peugeot was just over £400, their badge'd dpf was over £600, so I went with the pattern part.
A few weeks ago something in my DPF housing snapped off the tip of my EGT sensor, it sits just above the DPF, I fear it is the DOC, Diesel Oxidation Catalyst.
I am yet to establish if the garage disposed of my genuine CAT & DPF in favour of an all in one piece CAT & DPF.
If they have, they have thrown away an £861 DOC / CAT at today's prices, yes £861 just for the CAT and £701 for the cheaper DPF.
Fortunately my car still regenerates but not without an 'anti pollution' AND 'risk of filer blocking' info message prior to the regen.
Back in 2017 when I first got the 308 with 135000 miles, every time I started the engine, I'd get an 'info message - Risk of Filter Blocking'
Peugeot charged me £50 to tell me the original DPF was at 65% of its life, but not why I was getting the message or how to stop it.
After some research, they then charged me another £50 when I told them to tell my car it has a new dpf.
No more messages or warnings.
That can be done in Diagbox under the dpf section and PACK REPAIR.
One can carry out a regen, reset the fap fluid level to full and reset the ash / soot counter by telling the car the DPF has been replaced (just 3 things)
My car has 150'000 odd miles now and Diagbox has no way of knowing my DPF had been changed so can't give me a life span, it just figures it needs to be changed.
I wish I had kept my genuine parts and had the DPF professionally cleaned / back flushed.
Though looking at some used DPFs on ebay, the outside look very rusty as I'm sure my original was.
Euro Car Parts always have discount codes of 40% and sometimes 45% so their cheaper complete CAT / DPF is less than £200.
or this link below for £245
I need to establish what had broken my EGT sensor and why the replacement did not push into the hole, there was something there, probably the DOC.
I had to make a hole with a screw driver to fit the new EGT sensor.
Everything works but something is wrong.
The differential pressure, usually at 30 mBar at 60 mph is sitting close to 100 mBar.
Was my local garage supplied a poor quality dpf assembly or a good one that just fell to bits prematurely.
I need to contact them to see where I stand.
Some manufactures give 3 year warranty.
