D4D problems seems VERY widespread

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

One faulty car does not mean they are all faulty. Using that logic and based on my delivery experience all the autos must be faulty...

But this is what this thread is trying to establish, it seems this problem isn't just 1 car, and it also seems it's not just our "Shitty" diesel!!! It's happening to numerous Prados, Other vehicles with D4Ds and also seems to be causing problems in other countries.

Also if it is our diesel, why are toyota selling the D4D in Australia if it can't handle the diesel that is available to us???

i think it is just an australian teething problem that toyota aust will sort out.
when?
when they have a "fix".
the other country's that a similar sound is heard, what fuel quality do they have?
with any new type of design/technology, there will always be small
bumps along the way.
this is how we end up with a good product.
just is alittle rough to get there, but toyota will.

But what it it "Shits" itself miles from anywhere!!! Mav seems to do quite a few long trips and the last thing he needs is the D4D falling over.

I would still be getting paid by the hour as its a work car. As for Mav I do not in anyway disagree with him. He is doing what he feels best, I just personally feel the topic is getting blown out of proportion with 'new' prado owners feel like they are driving a ticking time bomb.

A fellow workmate's hliux ute had a leaking rear diff which was reported and inspected as soon as he could get it in. They had to order the parts so it was expected that he keep driving it for a week or so until they could get it in. In this time the diff let go, and locked up the wheels @ 100km/hr. The vehicle drifted of the road and had to be thrown down the dropoff off the side of the road or it may have rolled.
Its a case of a simple problem turning into a much greater/expensive problem, so if you think that you have a problem get it looked at. Imo a little noise for me isnt a big problem. I always use Shell diesel, regular sercving & it still drives find with ample power.

Don't get me wrong, Im not into driving cars with known problems (Hey they expected me to keep driving it while I was waiting for a new rego label to come in the post, after rego ran out :shock: )

1KZ's have being known to cylinder head/head gaskets blow, but I will still drive it to fraser etc. & have faith in mr toyota. Just a matter or looking after it and keeping an eye on things.

Do you have proof? Not 'I read it on the Internet so it must be true', so far it's only Mav who has a confirmed fault.

Personally I don't see a need for alarm. Especially in the case of new vehicles. My daily drive is an may07 D4D with 60K. Yes, its noisy at startup on a cold morning, but imo I dont see that as a major catastraphy. If its shits itself then It will get fixed under warranty, but theres no need to ride toyota until then.

This is exactly how I feel. If it shits itself in the middle of nowhere then I'll deal with that. Just like any car that can break down anywhere.

I'm even running mine on 50/50 bio!

Martybuzz, I am not going to say that using bio-diesel is risky but this is a quote from a post on D4D damage from the ExploreOz.com forums:

************************************************** ***********

The reason Toyota does not reconmend biodiesel is the damage it can cause to injection systems.

We are Denso service dealers and at a recent conferance we discused biodiesel.

Denso have done tests on injectors and found after 1000k with a 2-5% mix there was signs of injector damage.

This is highlited even more in common rail systems were tolarances are even greater.

They showed us photos under a microscope and the spray patterns to back up the claim.

The injectors in the D4d engine has a piston to bore clearance of 2 microns.

It seems it is traced to the solvents and other chemicals used in biodiesel.

NOW BEFORE SOMEONE GETS HERE AND SAYS THAT I AM TALKING SH** consider Denso is not affiliated with or has to be with any oil companys and they are the number one maker of diesel fuel injection systems and components.

If someone is going to knock me down on this, show the proof technicaly I will agree with you.

Denso stated to us it is in there best interests to suport renewable fuel source and that they were following the hydrocarbon to liquid outcome with interest.

And to jdpatrol biodiesel is still greenhouse warming, the main claim to fame is it is renewable energy and there is a strong belief that biodiesel may be worse for the enviroment with a higher GWP the standard diesel.

It has been said that to make biodiesel economical it has to be under 80 cents a Lt.

I would be asking the biodiesel sellers if the will warrant the product that it will not cause any damage in the short or long term to your engine/injection system........... they all say it is safe so get them to put it into writing.

So at the end of the day if something in your injection system goes haywire and its under warranty with Toyota and biodiesel has been used..... even a tank full and the part has to go back to Denso for evaluation (they take the quality issues very very very seriously) the chances of your claim getting accepted is zero!

I am not for or against biodiesel, but when the facts get stacked up it make you wonder....save 20c per lt. now may cost you big later.

Perhaps I should say use it and here is my business card, if you have any problems I would love to make some money from you.

regards Richard

At least you can make an informed decision on using bio-diesel and weigh up the effects versus the savings. :wink:

Well, you won't make any money from me I'm afraid. If anything goes wrong, which I doubt, I'll cross that bridge when I come to it.

They had to show photos under a microscope? This is a diesel we're talking about, not a finely tuned high performance engine.

I think there is a lot of scare mongering and sensationalism going on.

Why would Peugeot recommend the use of Bio, but not Toyota? All very strange and why I take it on board, but try things for myself.

The one good thing is we can discuss it on here

Yes it is a diesel, but it is also incorporates high technology and a finely tuned engine these days.
The engine and fuel system tolerances and room for bad fuel are nearly non-existant. Not like the old 60 series which needed a dose of 'start you bastard' on a cold morning to get it going.
The ratio of defective engines worldwide would be less than 1% but that does not mean it is acceptable, especially at $60k per vehicle.
Its all well and good to say we would deal with the breakdown if and when it happened, but what if you were on Fraser at low tide with the truck fully loaded with your gear, the tides about to turn and the Prado snuffs it???
Toyota will only fix the fault, not replace the losses incurred...

I know I'd rather drive a toyota than a Kia. Heard an interview on the ABC today, a fella bought a brand new Kia 15 months ago, Kia's after service is so good they've given him 3 brand new engines to go with it.
The last 2 replaced the original
Great after sales service, crap car!

Someone had a go at me for even daring to suggest I wait until the next model before contemplating the D4D even though that person had covered a mere 100,000km himself... Just goes to show my gut instincts were correct.

Nay, I decided on the petrol V6 version instead because the gummint did the math for me.

Sorry for not adding anything worthwhile to the discussion but I do sympathise with D4D owners who are affected. You'd wonder how this happens with modern engines... but all makes have problems. If you believe otherwise, you are an absolute dill.

Sorry to sound negative (and before you get angry, yes, I read you'd be hesitant about recommending the D4D)... but soon Toyota would be blaming the oil companies for the high sulfur content in the diesel fuel sold here. I'd be first to ask if other makers have similar problems with biodiesel. If not, then the ball is in Toyota's court as far as I (the potential consumer) is concerned.

A bit cynical of me you might think? Well Toyota did blame the thousands of owners with sludge issues in their Camrys (in the US) before agreeing to rectify the problem for affected owners.

Why would I get angry? You will notice that I merely quoted someone who is a Denso rep they were not my words as such.

I have also said that to be fair to Toyota it is also a problem for other car manufacturers that use CRD engines, we on here mostly have experience with the D4D which is why it seems we are only accusing it in isolation to others.

I have a Jan 07 build D4D going back for its fourth Toyota repair and injector replacement.
I agree that the incidence is probably small in the total number of D4D sales, but that doesn't diminish the hassle i have experienced.
It is a Fxxkn pain in the arse dealing with dumb Toyota repair people who appear to be unaware of any problem and try to tell me that it is worth spending premium money to keep the feeling when they appear to know shxt.
I love my car but i have limited money and spent $56K hoping to keep the car for 300K+. So it leaves a bad taste in my mouth, when the Toyota dealer on the fourth visit (having not solved it on the previous three) says: 'Are you OK to catch the train again today?' (while we wait for injectors to come in from Brisbane to try to fix the knocking).

[IRON-PAWW Avid PP Poster! Find all posts View Profile Close IRON-PAWW]

Catch the train?? No way in friggin burning Hell will I accept that if it happens to me. Not good enough. Plain and simple. A loan car is the least that could be done in a situation like that.

With most retail goods, if you take an item back with the same fault for a third time within the warranty period you are entitled to get your money back! Sounds good to me!

to answer this topic.
i 'm guessing it is.
i have just gotten my hands on a 3pg pamphlet from the toyota service department,
regarding

important information please read carefully
fuel system
for common rail diesel engines

why else would they put this out,
and i must say it is worded very well.
