Re: The D4D Death Shudder

So far 2010 is not a good year for me. It started with the guy not giving way at the roundabout. No sooner had the panel beater started work and they found the front inner guards on both sides had badly cracked (all genuine Toyota bullbar and winch fitted) and now the 'Death Shudder". Things can only get better ..... I think

Sorry to hear about all of your problems PeteS. 200k is hardly encouraging life from a diesel. With regard to your inner guards, what kind of life has the car had? I would be interested to know how much time you have spent on corrugated/off road situations or was it due to the accident the vehicle had been involved in.

Neil

Re: diesel rattle in D4D Prado

Starting this process tomorrow of getting the cold start rattle fixed. I have checked in my D4D (late 2007 62,000kms), with Toyota this afternoon and asked them to leave it parked outside and road test it first thing tomorrow morning to identify that there is a problem when cold. Will let you know how I go, its going to be a long process by the sound of it but I have told them I will not be picking up the truck until they have ordered the parts to fix it.

I wish you luck, hope you have a win!

Toyota just rang me to say they have upgraded the engine management software and will be holding on to the car to test it cold in the morning, will see how they go.

Hi Neil

The cracks are definetely not related to the accident, these are stress cracks and as I have since found out very common. I keep a daily travel log of the distance on black top and dirt roads along with the road conditions. I just did a quick check of my spreadsheet and the amount of time on dirt/corrugations would be under 6,500km. So far Toyota have not been able to answer my question as to what the fix is.

I received notification today that each injector has been tested with no problems found. I can't believe after all this time there is still no reason for the piston hole.

Cheers
PeteS

Re: diesel rattle in D4D Prado

Well I tested the car this morning and the cold start rattle is a lot less noticeable after the ECU update. Service manager at Toyota reckons in 1000kms it should be even better.

This guy also said the ECU update fixes 90% of D4D's that come in for the cold start rattle. Will see how it is in another 1000kms.

I think I must have one of the remaining 10% vehicles

Re: The D4D Death Shudder

Well here I am, it's over a month since the "D4D Death Shudder" occured and I'm still no closer to knowing the cause of the hole in the piston. All the injectors have now tested fine.

I was hoping they would find a problem somewhere. How can anything be fixed properly if they don't know the real cause. Will it happen again :?: have they missed something :?: :roll:

Stinks of a cover up imo, they would never admit to the injectors being faulty.

Re: diesel rattle in D4D Prado

There has been mention in here of a date where the "new" type of non rattle injectors were factory fitted, can anyone tell me what that date is (without me having to troll through the 47 pages to find it)?

I have a mate keen on a D4D but he only wants to look at vehicles after that date. I presume the new ones are still looking OK (no rattles etc)?

I do recommend you read the 47 pages! I spent a whole afternoon doing it and it pointed me in the right direction to fix my death rattle. From memory the new injectors were fitted around March 2008 onwards. I have a 2007 model now fitted with the new injectors and all is running well (touch wood) ~10000k later.

Re: diesel rattle in D4D Prado

It obviously only affects a few of the earlier D4D engines. Mine is a december 07 and I have now done about 50,000kms without any issues.
My FIL frequently travels to Japan to source various mechanical components. In 2007 Japan was hit by a huge earth quake. He reckons that several components containing tungsten were sub standard for a period of time after the quake. That may be part of the reason some injectors have failed????
D4D= Fantastic engine IMO.

I usually do over 50k kms per anum so time will tell I suppose.

Re: diesel rattle in D4D Prado

Hello all

Well it was a sad day today...."OH WHAT A FEELING"...

The truck went in for a warranty job (front LHS shaft seal was leaking) - evident at 40k service. At the service, I made comment that the car does the "cold shudder" after a few kms from cold and fixed once in neutral and then back into drive. They wanted it overnight to do their own checks...I dropped it off Tues night on way home from work.

well - i got it back tonight - and yes, the drive shaft seal was replaced (thankyou Mr Toyo) and they also re-flashed the ECU. Hmm....i guess i am truly a member of this club now. :roll:

(claiming ignorance of being well informed via Pradopoint) - I played "dumb" and left it to the service manager to pretty much summarise what everyone here has said. The problem is global and effects D4D motors in Prados, Hiluxes and Hiaces. The strange thing - not every motor that is a D4D is affected. Some....and i think from the way he made his remark, some = way too many.

He said the std Mr Toyo policy is the injector parameters have been measured (no idea what they are but i would like a copy for my records) and Toyo now have them. I need to report back in 1000 kms time with "yes fixed" or "not fixed".

I mentioned "if not fixed, what next" - and he said that Mr Toyo will advise what injectors (plural) to be replaced. Continuing my stance of being ignorant, i suggested if they would replace them with the same type would just repeat the issue and he said - yes that was the case early on but they now have new injectors which do not show the same problems. He also said, the 150 series - as far as he is aware - not had this problem yet and the injectors are on that motor.

So - my trip meter is now reset and im eagerly awaiting starting the car tomorrow to see how the shudder goes.

:cry:

cheerio

Re: diesel rattle in D4D Prado

I have the same problem on a 2007 d4d. Toyota fixed the problem today. They said the problem is pre injection timing when cold, they re flash the cpu to correct problem. Good old Toyota....well see if it does fix it.

Re: diesel rattle in D4D Prado. is it over?

I've been following this post for many months. I've noticed the postings from owners suffering this problem, has dropped off.
Has this problem run it's course? That is , if you were suffer this prob, it would have developed by now.
Or it because we've been having warm weather, this problem has declined.
will winter cause a rise in new rattly prado's ?
