Just spoke to him. He had backed right off as fuel consumption went right up. He had taken breaks. He was passed by every other car and truck heading north including lots towing much bigger vans than his with a variety of brand diesel 4x4s and even Commodores with big vans. At 80 km the transmission was locking up in 4th as it should. These were conditions that everyone who tows up the centre experiences. The Prado was far under maximum weight [ had been weighed before trip to make sure]. He was familiar with Prados as his previous 150 did 100,000+ km towing the same van and he has huge towing experience. The point still remains that a new car should be fit for purpose and something is clearly amiss here! Meanwhile the car and caravan are on a truck back to Port Augusta tomorrow to the Toyota dealer there. We await the verdict from Toyota [ who did not answer emails and calls today]. All who have 1GD s or plan to buy a new Prado diesel should be following this VERY carefully and asking LOTS of questions when we have services etc. A car that cant do what it is supposed to do is a danger in inland Australia with its huge distances, number of people towing, strong headwinds etc. and is not fit for purpose. Lets hope this IS a one off and not the start of another D4D saga. Did Toyota test maximum towing load in hot inland conditions over long distances day after day in inland Australia? By the way, new 200s have a DPF as well.

That's all good detail that I'm sure he'll be giving to the dealer.
I'd hope this is a rare issue and its the first PP report of DPF failure so a long way from the whole 1GD programme not being fit for purpose. Certainly though something amiss and I look forward to your update when they have a diagnosis.
I'm almost 12 months in with around 5,000 towing, but like you, now crossing my fingers this is a one in a million event.Cheers

Don't we all! Mechanic in Coober Pedy says he has seen 3 DPF issues but not on Prados and he managed to clear all of them but not this one! We assume that about 5000-10000 of this motor have been sold in Prados in the last 12 months plus those in Fortuners and Hi luxes. Also lots sold in Europe but very different conditions there. Let''s hope that this is a one off that can be explained and fixed quickly. In the meantime it has destroyed my friend's trip and faith in his new Prado.

Makes me wonder of the future of diesels in the light vehicle market, say in 10 years or so. The emissions regs for diesels are getting out of control with all the complexity. Recently someone posted some details on the all the variants of the 1GD. We don't even have the most stringent version of the engine. Ours is the Euro5 version where as there is also a Euro6 version with the additional urea injection of top of the DPF and EGR that we get. So much crapped bolted on these engines these days with more stuff to go wrong.
With the worldwide diesel scandal going on currently, I do wonder if Toyota are going to stick with the diesels after the next Prado runs it course circa 2025 or so. I have a feeling we'll be seeing turbo petrols or even hybrid petrols in the distant future.

As suggested earlier an led or signal should be present on the dash when a burn is occuring. There should also be some feedback mechanism available with the ECU which intern can be shown with a scanguage or similar. Anyone know how this might be achieved with the Scanguage?

Hope he gets some answers about this and gets it sorted. The addition of DPF's will end my love affair with Toyota diesels. I had major dramas with a Subaru Forester diesel a few years back. That car travelled 200 km's a day on the highway and i didn't baby it or lug it either. Still went into limp mode on me numerous times with oil-dilution and DPF issues. Real safe when your travelling on the highway! I don't think people realise either that the DPF will not last the life of the engine. It eventually gets clogged with ash, which cannot be burnt off, and the whole unit must be replaced. With the subaru i could get the soot accumulation ratio and the cumulative ash ratio figures printed out for me and attached to the service paperwork. It gave me an idea on how the DPF was travelling and how much it was blocking up. Mutiple brands are all having DPF issues, and a lot of it comes down to the use and driving style of the buyer. Lugging the engine around town, taking it on short trips down the shops etc. will all clog the DPF up quicker. It shouldn't be like that with a new car, i agree, but it seems to be a factor. Does the Prado owners manual say that if the DPF light comes on you should take it for a 20-odd minute run up the highway in a lower gear to force a regen?1979 BJ40

I had my 10,000km/6 month service completed today and had a few things that I wanted looked at such as an increase in engine noise/rattle under acceleration, single engine knock at start up and an increase in fuel consumption.
Upon picking it up they said that the dpf was 60% clogged as a result of the factory computer and injector settings, which they related to the issues. They said they did a forced regen and reset/relearn the injectors. Toyota said that they are regularly finding that the original factory settings in the 2.8 are causing issues from lack of power to clogged dpf's and after doing what they did to mine today it has stopped those issues. I've only driven the car home for 10 min but it does seem much better.
404pug if your mate hasn't had his first proper service yet and not had these things updated, then it may have contributed to the issue he experienced.

I just had my 10k service last month and nothing mentioned about the DPF at all. Maybe because I didn't complain about any issue related to fuel or motor. Might ask if they do check the DPF and what level it was at. Wonder if its possible for us to be able to obtain this information somehow with a OBD2 connection?

Yep I have read that also however the Prado has a different system. The old school of DPF use the engine heat to breakdown the soot whereas the Prado has a seperate DPF unit where diesel is injected post engine which is much more efficient and less detrimental to engine wear etc.
The ECU is programmed to do a burn no matter the circumstances anywhere between 200 and 300km (based on algorithm that works out fuel usage and km's travelled). This is what has been explained to me by Toyota WA.
