DPF and white smoke

[netjam Lurker Find all posts View Profile Close netjam]

I've 2018 model and no issues so far but only 7k done. However, Hilux is the most selling vehicle and Prado on top for the large SUV. https://www.caradvice.com.au/672896/...vehicle-sales/ . So go figure...

Hi, what did you do to your car? Did you get a 2018 spec car? My car's dpf burns every 170km now, and smoke started to appear as well.

Does anyone know what is DPF Assembly? Is DPF part of the Assembly or a separate part? Thanks

If 2018 model doesn't have the issue I'll probably have to get one.

I upgraded to the newer model as the front end and some of the safety features are far superior. The DPF is still in the newer model however have changed the ECU firmware to make the DPF behave differently and it seems to be working very well at the moment.

2016 GXL 53000km just had my first look at the white smoke of doom. Happened twice in a week. Into Toyota and they've done the obligatory burn & ecu update. "DPF Good - No further action" OK...excellent.
Now to wait and see if I have any further issues, will update as time goes on, cheers.

Don't know if anyone has an idea of the new ecu update. Mine was reflashed last week. After that I have put more than 500km on it and got no burns at all. Brought it back to the dealer and they said it supposes to be like that for the new update. They have no clue how long it is going to be between burns now. What should I do? Just wait for another 500km or one of the light goes on?

Fine, it started a burn right after I left the above post. The burn last 15mins for continue city driving on an average 45km/h. No smoke was spoted during it. Hope they found the cure. 500km? seriously?

If anyone is interested here is a graph of the soot % recalculation from my not updated yet Prado.
It had covered 160 Km's since the last regeneration and you can see the % coming down fro 78% to 42% without any DPF rise in temperature or as far as I can see any other parameters changed.
Please ask if you would like to see graphs of any other parameters that may be relevant.

Yesterday DPF % went to 0 after the burn, usually it's 4 or 6. However, I should note engine was working hard, fully loaded vehicle driven on freeway and then mostly with L4 through Victoria High Country. Second burn with in 24h period

The Exhaust Temp you are showing doesn't look like the temp in front of the DPF. It looks like what I see further back up the pipe for the speeds you are showing.
As the DPF saturation declines to around 40% I'm seeing low-mid 500C temps. Once DPF drops below 40% I'm seeing the temps rise to 600-700C.

I have now clocked 20,000Km in my 2018 GXL. and driven a few desert/mountain tracks in that.
Averaging about 350Kms between burns.
The quickest burns (6-8 Kms) have been during slow or low range driving/crawling.
Around the city its taking around 22Kms (including parking in-between), and on the highway 70-80Kms @ 100-110Km/hr.
Had a heart stopping drive on a highway when it took just 100Km to get from 0% to 100% (it jumped from 2% to 52% in 15Kms), then took 132 Kms to complete the next burn.

But all returned to normal after that.

Toyota have just really not cared about this issue, every day driving I see a white smoke plump from a hilux/Prado if you caught right behind one its bad.

Hopefully this forces Toyota to do a correct recall but to also work out how to get the system to work if possible.

I have filled in the contact form on the above website but I am not sure how many people will bother. I am amazed at how loyal some Toyota customers appear to be. There is a post on another forum from an owner who has had two DPF changes and now needs a turbo. He reports how well Toyota have treated him and says that his turbo "should now be good for another 100,000 Kms"
I would think that it is reasonable to expect a DPF and a turbo to last much longer than this????

I put my name down for the class action , only because i feel Toyota should be more accountable for getting this system right in the first place. Its fine for them to say that DPF issues will be covered out of warranty , but how long will that promise hold up?

My 2016 VX had the ECU update/recall earlier this week and I find that the DPF now goes from 0%-100% very quickly. Tonight for instance, I drove 10km and it went up10% from 38%-48% and yesterday when I drove 15km, it went up 16%. I also find the fuel consumption has jumped up quite significantly, but I haven't done enough kms after the changes to really say this for sure. Does anyone else experience the same things after the update? P.S. I put my name down on the Bannister Las Class action as well.

Hi 2016VX,

I've got similar sitituation here, 2018 VX, had ECU update/recall three weeks ago, as the technical staff said, that update/recall was all about DPF burns, "it will burn more often, and will finish a burn more quickly". While I haven't noticed any increasing fuel consumption yet, probably due to highway driving, but the regeneration was finished REALLY quickly, I felt like those burns were done within 5-8 minutes (that was 20-40 mins before update). In term of frequency, I will keep eyes on the burns km wise, and then post results shortly.

[JohnLynn Senior Member Find all posts View Profile Close JohnLynn]

Could I ask 2016VX if he means that his % rises quickly to 100 then starts a regeneration without the "recalculation" that I have shown the graphs for above?
I think that the reported faster and presumably hotter burn must be a good thing but I am not so sure about more frequent burns? A Fortuner owner who's vehicle has had the update some time ago has said that when under heavier load like towing his % is maintained as the temperature increases enough to delay the increase in % soot, in other words passive regeneration at least to some degree.
My late 2015 GXL will be having it's final capped service in a couple of weeks, I will make some recordings before and after the update under varying conditions.
