DPF issues with 2019 Prado?

[CsM Lurker Find all posts View Profile Close CsM]

HI all,

First post here.

I'm looking at buying a 2019 GXL Prado and am wondering if the DPF issues with the previous models have been eliminated with the introduction of the manual DPF burn switch.

Ive got no experience with diesel fueled vehicles and would appreciate any information on the subject.

Thanks in advance
Csm

You should find a lot of comments on here and also on Fortuner and HiLux forums so good luck with reading them all. As you probably know there is an ongoing class action about the DPF issue, it seems paused at present as Toyota have been asked to provide more information. (Don't hold your breath)
They have made some software changes which affects how the regeneration happens and I expect Toyota will say that the problem is fixed but there are people reporting that have had DPF's replaced on recently made vehicles, but also people saying they have encountered no trouble at all. So my opinion is that the jury is still out, it will be interesting to see what others think.

From what a have read and researched the manual burn switch is just a band-aid, The filters are still blocking up and if you don't drive long distances regularly to get the system up to a high temperature to preform a burn they will block up.
I was looking at buying a Fortuner some time next year but i think i have scared myself into re thinking my purchase.This is from the US but explanes some interesting problems with modern diesels

I have a Oct 18 build VX which just clocked over 15,000kms the majority of which have been short runs around Brisbane, in that time I have only been aware of a DPF burn once. I have had no issues at all with the DPF system. FYI I am a mechanic who now works off the tools in sales & tech support for a diesel manufacturer so am very aware of how the engines and systems work.
The manual burn switch will only work when the DPF is over a specific percentage “full”. The idea that being able to push a button whenever one wants to do a burn would fix the issue is IMO rather naive. From what I have seen I think Toyota probably has the programming right now but it will take a while for that to be confirmed.
I drive 1000km a week in my work vehicle in city & highway traffic and rarely see signs of DPF issues these days.

I have a 2019 gxl and have 29,000km and no issues touch wood! All seems well car seems like it drives better and had more responses now as I get more km on it

What Leethal said. Late 2018 VX with 15,000 trouble free k’s.

I have a 2018 GXL with 55,000Km on the clock. I have a Scangauge monitoring the DPF and seen no real issues so far.
I also had the manual DPF button retrofitted and Custom Mode enabled. That works too. I only really wanted it for when about to drive over miles of tinder dry straw grass or spinifex when the DPF is near 100%.

Doing short drives only might be problematic.
When a DPF burn is underway and you stop the car, the ECU remembers it needs to complete the burn.
When you resume driving, but with a cold engine, it can take 5-8Km on a winters day to warm up enough for the DPF burn to resume. In that time the DPF would have sooted up a little more.
So if you mostly do such short trips, the DPF regen process could conceivably never complete, at which point the DPF light will come on.

Also, the 5th injector sits in its own chamber. From some videos I've seen that chamber can soot up (possibly due to the short trips scenario).
When that happens the flow of fuel for the DPF burn gets choked.
However cleaning the 5th injector chamber looks like a straight forward job.
It probably should at least be inspected every 100K Kms or so anyway (like the EGR Valve IMHO).
