DPF and white smoke

[JohnLynn]

Well that is interesting, thanks for letting me know, I will have a look into it this evening when I get time. My Prado is late 2015, it has only covered about 30,000 as far as I remember but purists may be put off by the fact it obviously is way past the next service date although it was serviced before being stood on axle stands with battery off and full of diesel in March 2020.
Fascinating that they changed your DPF without you reporting any trouble with it, like you I constantly monitored mine with torque pro and occasionally the hacked Toyota program, (cant remember its name lol) and it behaved as it should so I am very curious to hear what the dealer says when or if I ever get the chance to return to WA. I had a friend surrender the plates, this is all strange to me as the UK have what is known as a "SORN" declaration. All you do is notify the DVLA that the vehicle is off the road and just reapply for road tax when you want. Btw SORN is statutory off road notification, there is an annual "MOT" (ministry of transport) road worthiness test, but if you put it back on the road before this expires there is no "over the pits" test or whatever it is called in Oz.

Extended warranty applies to vehicles up to mid 2018.Get access to your "Toyota Account". It needs an app on your mobile and then a password. They keep records of your maintenance and updates etc.

When I put my early 2018 GXL in for 80,000Km service this year the Dealer was required by Toyota to replace the DPF system. I had a Scangauge reading it from day 1 and it has been working just fine. I generally don't do short trips.
The new DPF has some changes to mitigate a 5th injector clogging problem amongst others.
All 150s from late 2018 on-wards also have the manual button, which can be retrofitted.

PS. Your Prado is worth its weight in precious metals at the moment. Sell it.

Good to see you back posting on here CamJam, I still regularly read the forum despite being stuck in the UK fully vaccinated but regarded by WA as a vector of contagion so not allowed back. I have not even seen my Prado since March 2020 and not expecting to get back any time soon. I have started to worry that the extended guarantee will have expired before I am able to use the car again. I see the class action is slowly dragging on while the lawyers rake in the dollars and wonder what the outcome will be. It would be nice for owners especially like me with very low Km's could have the reassurance that all vehicles could be upgraded to whatever system is used now. I presume that the latest models are OK????

DPF warranty extension

25-08-2020, 06:04 PM




Today I was pleasantly surprised to find a letter from Toyota in my letterbox.
Toyota wrote to announce the DPF is now covered by a 10 year , unlimited km,warranty.
This also includes the cost of towing and a replacement car if required.
I had no idea Toyota was making this offer. The class action in the courts, clearly is working.
Im unsure if the warranty extension, applies to all DPF diesels, or just my Jan 2016 build.
This letter should improve my resale value and provide peace of mind.

That was what I was pushing for before I finally gave up the cause and sold my Prado. While a warranty won't help you out the back of nowhere in a recovery because your DPF is cactus, you'd at least have a leg to stand on should the recovery cost a large amount of money to effect.

For what it's worth (been a while on here) - after two and a half years of fighting Toyota since I sold my Prado, they stumped up all costs I had for the DPF issue. They saw what I paid for it, added what I had added to it (with receipts), deducted the sale price of it, and paid for the time off work that I had to have to get the DPF sorted.

Still highly unimpressed, but I guess that's the fight you have to go through when you're an early adopter of the new 2.8 engine with DPF and they don't believe their quality control nor their engineers could possibly be at fault. Here's hoping this long lesson for Toyota has taught them a thing or to about customer service. I might add (and said it elsewhere) my local Toyota mob (Canberra, Phillip) were brilliant. It was TCMA that dragged the chain.

Check with Toyota Australia, or your friendly Dealer.
Like me you probably got an unlimited 10 year warranty (from date of purchase) on your DPF a year or 2 back.
I wasnt informed until I asked them about it. Then I got the confirmation letter.

The DPF system on our 2017 1GD-FTV 2.8 seems to have been operating ok for the 53,000 km it has driven, until yesterday when I noticed a huge cloud of smoke while it was performing a burn.

Vehicle had been in for the DPF system upgrade a couple of years ago, obviously it's not a permanent fix.

Interestingly I have noticed a marked increase in fuel consumption lately when it has been performing a burn so was wondering if something was amiss. I Decided to remove the DPF injector housing and found the hole in the housing where the injector should spray fuel through was completely blocked. I suspect the DPF filter is probably not being regenerated properly, hopefully cleaning it will have fixed it and allow regen to occur correctly, otherwise it's off to Toyota.

I suspect that cleaning the DPF injector housing will become a regular service inspection/clean item every 10-20,000km. Luckliy it's quite easy to do.

Doesn't appear to make any difference to mine..

How often DPF burn cycle is triggered in vehicles with catch cans? Will it be clogging DPF slower?

Just back from a 9000Km trip to the Kimberley including the Oombulgurri/Carson River Track, Kalumburu & Gibb Roads, Tanami plus & 6Kkm of bitumen.
Had to replace the windscreen at short notice in Kununurra (everybody keeps spares for Toyota's up there), after a Road Train hurled a stone at it.

I logged all 45 DPF burns on my 2018 Prado GXL.
The highway (100-110Km/hr) Regens occurred about every 148Km and took about 30Km to complete. A few DPF Regens started after only 80-90 Kms.

We took 10 days to drive the 430Km Carson River Track. The first 3 days we hardly covered 35Km a day, driving in low range, doing 5-15Km/hr for hours on end. Bent a few under body bash plates and the factory side steps.

9 vehicles in the convoy of which 3 had DPFs, 1 Prado, 1 70 Series Ute and 1 Shorty Pajero.
The 2 Regens on my Prado took 2Kms to complete (whilst driving over tinder dry straw grass over a meter high).
7 flat tyres across the group. The lead vehicle, a 79 Series, broke a tie rod end, we had spares.
The same vehicle broke another on the Gibb River Road at speed. It ended inelegantly with the front wheels splayed out and the front drive train bent heavily.

My vehicle has now clocked 40,000km and the DPF seems to be doing its thing, so far.

I would like to know how they do it as well but I doubt they tell their own mechanics let alone customers. I agree with you that it is probably monitoring the pressure in and out, after all that seems the most common sense thing to do, but then things things don't necessarily follow common sense.

Weve got a 2015 GXL, and Ive had the custom mode (ie DPF light flashes on the dash) activated and is working. Were currently doing a year driving around Oz, towing a camper trailer. Ours is a manual, I normally sit on 2000 RPM when cruising depending on the roads - ie 100 km/hr in 6th on bitumen, maybe 80 km/hr in 5th on gravel but both around 2000 rpm. Monitor when it burns with the trip meter.

I reckon it burns based on a set number of engine revolutions - i get 300 km between burns at 100 km/hr, but only 250? when cruising at 80 (also allowing for slow downs/speed ups into and out of corners/grids etc).

I saw 150km and 170km when travelling at 110km/h for about 3hrs. Toyota are looking at the DPF today and tomorrow. Still cant confirm if they are using the differential sensors to determine how full DPF is. My guess is yes it does use the feedback. An example would be that it sees a partial blockage so decreases the km's to full so that a burn is initiated early to remove said blockage. I have also seen other behaviour which indicates the use of the sensors. If I stomp the accelerator sometimes I can see a 2% increase in how full DPF is but once I back off the percentage drops back by 2%. Would really love to know how Toyota have setup the behaviour of a burn.

Well who'd thunk it? Mine actually did a burn today AND the light actually flashed! 255 km since the last service and dpf fiddle. The burn lasted 7 km. All of the 255km are outer suburban kms with some of it at 80-100 kph. Of course the button did nothing.
