I recorded over 200 trips on my 2017 Discovery Sport to find out if its DPF is fit for purpose

What part of my posts you deleted needed moderising?
What harm is my viewpoint causing?
I don’t know your model or what it’s design spec is, so I cannot confirm your 1hr drive on the motorway as enough or not, or where you can come up with that number.
As for your other attachments I have no idea what they are of or from.
Also don’t understand the descriptions in the pics.
What does the JLR official doc say about DPF operation for your vehicle?
I know what it says for ours and it does what it says so why is yours a problem?

If the DPF is too blocked from the OP doing 5 mile school runs in his pyjamas for a fortnight, then runs at 50mph won't regen it.
It will need a forced regeneration.
And a change of vehicle more suited to his use.
Like a petrol Nissan Micra.
Do you want the info I have for my L322 that tells you how it works? Which goes into detail of how the ecu raises exhaust temps with injection, to raise temps in the DPF to do an active regen.
I gave the basics important details, and real world experience. I don’t need to log 200 trips it works.
So 200tdi you don’t even have to worry about an EGR or 2.

The swearing and personal insults, you know this, you're not a noob who doesn't know the form.
You're opinion is fine but I'm getting a little bored of reminding you when you aren't in AG.
It shouldnt be an issue, it's simply the rulz and has been since Ratty and Sirus' time and I was a noob.

Ok.
Dunno what swearing or personal insults, because they int there no more.
P.S. twice in about 10 years and you're getting bored of reminding me?
Pfffft.

Who remembers Rashe/Rache or what ever he was called and his class action against Landrover because his Freelander wasn't 4wd?
Oh the fun we had there!
I'm getting similar vibes here.

I don't normally comment on stuff like this - however....
The passive regeneration you show is slowing the build up of soot in the DPF not reducing, therefore extending the times between active regeneration. No manufacturer ever claims their vehicles can survive solely on passive regeneration, active regeneration will always be required. Should you wish to demonstrate the effectiveness of passive regeneration to yourself, then drive the vehicle so as to prevent passive regeneration and see how quickly the soot levels increase, then you'll see the value of passive regeneration.

I see your point. However, when I was driving on the German Autobahn, the soot buildup not only slowed down but reversed. The first arrow shows when I started the trip, and the second arrow shows when I ended it. Due to the high speed (90 mph+) on the motorway, the soot level ended up being the same at the end as it was at the beginning. Zero active regeneration was required.
Maybe cos you were generating high enough temps to effectively do a sort of active regen(not system induced) even though it shows passive.
Would you worry if you didn’t monitor it and didn’t get a light warning you something was wrong?
I.E the car is doing what it should.

Exactly as above - the temperature achieved was sufficient to passively reduce the soot levels. Maybe if you take time to read the 'description and operation' section of the workshop manual with regards to your vehicle's emission control systems, you'd save yourself getting obsessed with something that was forced upon all vehicle manufacturers by the EU with no thought as to the efficacy of it nor the science and engineering involved? If you wish to take issue with anyone, it's the EU and their Utopian ideals that should be in your crosshairs, not a vehicle manufacturer.

To be fair I'd worry if I'd just had to shell out 2 grand because of a blocked DPF
We had a RR Sport 3.0l in work recently, red DPF warning, EML and reduced power mode - the DPF soot level was way above the ceiling for forced regen (he'd ignored the amber warning, the initial red warning, the follow-on EML and only brought it in when it went into reduced power mode), we managed to carry out the 'replaced DPF' routine and take it for a regen drive before the sensors tripped into the 'red zone' again - it never ceases to amaze me how blinkered some drivers can be to what the car is telling them - in the main, blocked DPF's are a result of the drivers ignoring warnings, it almost always works out more expensive the longer you leave it...
LR manuals state something along the lines of 'if you get an amber exhaust filter warning, drive for a minimum of twenty minutes at around 40mph' which is good advice, the problem is that most will drive until the warning goes off - which is nowhere near long enough to get the soot levels down to the target range of 4-6g/m3.

I followed a few Discovery Sport forums for a while as I'd like to have bought one. Main issues are well known, DPF and timing chains and mainly linked to short journeys. We all know on these forums that short journeys kill quite a few modern diesels but a salesman isn't going to disclose this and lose his commission so uninformed people bought totally unsuitable vehicles. I'd also read that the DPF was mounted too far back on the DS so wasn't getting up to temperature quickly enough, thus the problems.
Class actions? I don't know, some may be ongoing but a lot of these are ambulance chasing solicitors vying for business.
Anyway, I'd read enough to put me off a DS, but personally I found this original post interesting.

So, basically the OP is a buffoon.
Which is what I said from the start.
Shame it was disappeared.

Aye,
totally this is why I had so much interest as if I had to replace the Defender it would likely with a Disco 4 and the whole DPF is new to me.
This is what the forum is about healthy debate and challenges. Quite happy if the OP turns out to be wrong but nice to hear all sides.
