DPF info

[DeadlyBeast]

Well Just read every post, am in the market for a 4X4 Hilux SR single cab auto...??
What do I do...??? 2019 models ,are they safe, is there a VIN # to make sure it is the latest and greatest ...???
It is for a motorhome , not a kids run with low K's, but it doesnt seem to matter...???

5 year warranty makes it sound a bit better, but roll out a swag at the dealers every month dont sound too good...!!!
vik... what say the clan...???

We have the an older 2017 model at work.
Goes for a big run 200-800km every other week.
Appears that these models get choked with short runs
Am yet to read about any thing changing with the 2019 models but then again haven't noticed any posts about DPF issues from anyone purchasing this year
Perhaps Toyota have fixed the short run low k problem
You should be fine if motorhome touring

Or is it maybe their last DPF software update that fixed it.
I havent noticed actually anyone complaining about dpf after that update.

I've had mine play up since the last update but it was just the 5th injector that was clogged. For me it seems to be every 50000km. Had it twice now and was the same both times. DPF itself has been fine. I'm doing about 1000+ km a week generally all highway.

[vik351]

What speed would that be blackpack, heard all sorts 80 ish is sposed to be the best for a burn off, 100 and over is no good

I would get the petrol if they had the model I wanted it in the way it's lookin, which is what the "s want...!!!

I'm sitting on 100km/h most of the time, don't often go anywhere with an 80 zone.

From watching the DPF temps with a scan gauge when its doing a regen I get higher temps with lower revs, so sitting on 100km/h in 6th burns hotter and quicker than staying back in 5th (I have a Manual).

Its the opposite to what the dealer had told me, they just said hold it down a gear and drive it harder to help the regen.

Does anyone use additive that car pars shops sell additives which suppose to help with DPF clean and prevent 5th injector clogging?

still ongoing issues , i was one of the first to get the superburn update , around August 2018 , and my DPF started smoking again and was replaced in April 2019 , with 42k on the clock. It does a burn every 200klm instead of 300klm and uses more fuel as a result.

[DeadlyBeast]

Has anyone heard if Toyota changed the angle/position of the 5th injector port post 2018?

THANKS FOR THE HELP.

I tried one the first time mine started playing up but didn't seem to do anything. I think it was the Penrite enviro+ DPF cleaner.

All additives do; is clean out your wallet.

I agree to a degree mate, but not all products are the same.
Some of them do amazing job (seal radiators, clean injectors etc).
Even dealerships and mechanics are using additives when they clean DPF systems.
It's just a matter of finding the ones that actually work.

I’ll add to this. I too had the update 6months ago (during a service) and haven’t had a puff of smoke since.
I first got the white cloud after about 23k and haven’t had one since 30k (6months ago).
They changed something.
BTW the dpf issue never effected performance or economy. It’s just dumping the collected carbon in an embarrassing fashion.

[grunf]

The main thing I noticed since the latest update is that DPF burn takes much longer on freeway speeds or if the engine is under any load.
Once in the suburbs, it finishes up quite quickly.

Appears as if Toyota went from one extreme to another. Before the update DPF burn was slow when driving at suburban speed, not it is the opposite.

[SilverSP]

I’ve noticed the DPF burn offs taking longer at highway speeds as well.
It can take 20-30 mins but running around the suburbs it’s half that time.
I suspect it’s taking longer to get the right temperature for burn off as higher wind speed is cooling the DPF off almost quicker than it can heat up.

Thanks for the information.
