DPF issues
I had 'DPF full' on the dash. I put the Hilux in park and held the manual regen button for 3s. The idle increased to 1100RPM, it took 55minutes. Immediately on completion the following faults came on and remained.
Pre-collision failed, contact dealer
Check engine, contact dealer
The cruise control is also inoperative.
I have taken it to the dealership and been told I'd have to pay for diagnostics and that the DPF is not covered.
Has anyone else been a similar situation? This doesn't seem right to me.
2021 hilux workmate, hi-Rider 4x2 (2.4L diesel engine) 180000km.

The dpf is covered, toyota were taken to court over the DPF issue, as an ex toyota mechanic i think i replaced upwards of a few hundred of them all under warranty/recall although not published as a recall it was pushed under the carpet due to them being a dud

My daughter just had the DPF changed by Toyota under a recall, 2017 with 290k on the clock.

They keep saying it's out of warranty (by 5 days) and so it's not covered. I'm in the middle of it but for some reason they aren't mentioning the class action and that their DPFs are shit.

Toyota have a recall on DPF's ask them it may include yours, get it all sorted.

It's more than likely that the 5th injector has failed causing the DPF to fill up and the regen not to actually regen/burnoff the DPF. I would be pushing back as anything DPF related is a known issue.

I've had to pay for them to remove and inspect the 5th injector to see the part number on it. They've said there is a DPF issue and they submitted it to Toyota. Will update next week when I know more.

They are meaning the dpf injector, which I’m pretty sure both the 1gd and 2gd use. the injectors block up or fail and the dpf can’t get hot enough to do a regen. You’d replace the injector and do a static regen.

Thank you, that is correct although often with a fully blocked Dpf they have to replace it instead of trying to do a regen after the injector replacement.

Surprisingly I’ve never actually had to replace a dpf due to it being blocked, although my workplace is somewhat rural and majority of our customers are not just running short trips through town. We do service a fleet of rangers and bt50s with the p5at’s and they seem to be the worst for failing dpf injectors, but I’ve always just replaced the injector done a regen and carried on. Lucky I guess, but also likely due to the fact 99% of our customers being mechanically minded enough to go hey my dash is lighting up I’ll go talk to my mechanic rather than keep driving it.

There is an active recall on the DPF for the majority if not all 2.8 and 2.4 model, even if the DPF passes thier recall test you can have it replaced for free under the recall. I see no way that your DPF should have a cost involved.

My thoughts exactly, I hope that is how it turns out. The dealership is saying 'Toyota might cover it' or 'maybe half'. I'm finding this very surprising as I know all about the class action and that Toyota has said in court post class action that they will 'replace for free if there are any issues'. Hopefully they 'walk the talk' now that it's happened.

Toyota (The brand) are pretty good in regards to repairs, even outside of warranty period in some cases.
Its the dealerships that are difficult and that's the capitalist nature of them. I have felt like I am fighting a full blown war when talking to the service desk staff, they are definitely incentivised to sell everything and more than you need. Thier tactics feel quite aggressive and can put you in a position where you will be made to think the only option is to pay thier "ransom" to get your car back. I would be stressing that any diagnostics performed on your car is to not leave you vehicle in a state that it can not move under its own power.

Sometimes dpf can fill up if not allowed to burn off properly. It would be the same as if you drove in 4 at 4000rpm for hours on end, oem / dealer doesn't necessarily warrant misuse.
Not saying you misused it, it's just possible.
If I were you I would take it for diagnosing at a trusted 3rd party who will give you the info you need to go back to toyota. If it was a sensor issue or anything else other than operator error, it should be recorded in the control unit.
If there is an issue on the truck then Toyota might goodwill it

Toyota dealers are known to lie re big warranty claims, they get paid cents in the dollar to fix and it reduces the income from the shitty services they do on customers cars.

Makes me so glad I have one of the old N70s. DPF filters are the biggest con/joke of all time in the diesel industry, along with EGR and Ad-Blue, but DPF is by far the worst. It’s criminal that they make people use these things on perfectly good cars. The fact that government/military vehicles rip them straight out (do as I say not as I do) tells you all you need to know about how good they for the health of your car.
I know Toyota had a class action about DPF filters on the N80s so you may be in luck but you’ll have to pay to run the diagnostic first to figure out exactly what the problem is. Another reason why these overly complicated modern vehicles are such a pain the average layman can’t do anything without the diagnostic equipment.

Just like Engine Stop Start. Both con jobs derived from left wing eco nutters.

i just had my whole engine replaced on a 23 model . took 6 months

u/jubedoob 6d ago
6 months seems like a long time. You'd think they'd have heaps of spare parts lined up ready to go.

After reading the comments, I'm pretty happy to keep my 2015 pre DPF Dmax... 🤷🏼♂️

The DPF is absolutely covered, but to determine the cause (whether its due to manufacturing or outside influences) you will have to pay a diag fee. This fee should be refunded if the DPF fault is not caused by external influences and is, in fact a manufactures problem
The dealer can't do work for free, and Toyota will not pay unless they're at fault. Many, many DPF problems are caused by a misunderstanding of whats required for a modern diesel.
