That i wasnt driving it “properly”. Instead the dpf was not working at all (either a vaporiser or fuel pump issue), and ash built up to the point where it couldnt be cleaned with forced regeneration. Soot reached >180% levels. The vaporiser “splashes” diesel inside the filter to “burn” soot - at least that’s my understanding. The pump pushes said fuel. If either of the two are not working at full capacity then the filter needs frequent cleaning or wont clean at all leading to ash building up. The seller still wont admit fault, and instead they phrased it as a “goodwill repair”, probably to prevent other people from claiming repairs and to be able to gaslight them into thinking it’s an issue of their own doing. Nonetheless i am raising awareness with whoever i can, including how to use an obd to read their dpf status, frequency of cleanups, and failures to do so. I wish class action suits were a thing in the uk because i feel like a lot of people are taken for fools. Even if people drove short distances there is no clause signed when purchasing a car that you cant drive it short distances. I bought the vehicle to drive it as i see fit. If i cant then its not fit for purpose, end of story.

If your exhaust gasses arent hot enough to passively regenerate then you shouldn't have a diesel, and its something you should have been made aware of. These active regen DPFs exist to burn off (i.e. release the particulates) that were previously collected in the event that the DPF starts to get blocked due to not enough high temp for passive regeneration. For urban diesel drivers, this basically means that the DPF collects the particulates, and then just actively regen and releases them - defeating the point of a DPF. They are indiscriminate, and are just as likely to release particulates in the same environment in which they would otherwise trap them (short journeys in a city). These things basically result in the vehicle passing emission tests by saving the particulates, and then releasing them later in the same environment. It amazes me they are allowed. Anyway - thats not your fault - just me ranting about how pointless an active regen DPF is :) I hope that one day regulation realises that and clamps down on them.

You can't sell a product that is known to break down under reasonable use conditions and then attempt to charge the owner for fixing said product. If diesel engines simply can't be made more environment friendly then ban them, end of story.
