    You're correct... I was getting a little carried away, my apologies. After I read your post I actually sat down and had a good read of it. I guess I got a little confused with the picture on the front page which as you say is a different looking filter which I took as an optional/add on filter. ops: Sorry for the run around. I've removed from my post.

    Regarding the filter, the service manual seems to state changing them every 20,000kms. For instance in my book 40k, 60k, 80k etc services state change diesel filter.

    Cheers,

    No worries, Crammy. Mines done 26,000 now and had its service recently and I was not charged for a replacement fileter between the tanks. Which means it probably wasn't done. I will get on to it though. As a subnote I have always used BP Diesel and now BP Ultimate. No injector trouble yet.

      10,000km and no rattle. Maybe Mr Toyota put the decent injectors into the recent batch of motors? BP Ultimate claims to have lower sulphur levels. Aussie fuel has higher sulphur levels than European diesel. The Singapore sourced fuel oil is lower than Australian oil, so those in Darwin and Queensland might have cleaner fuel than the rest of us.

        Interesting update on all this - after pointing out that my 07 sounded like a Fordson Major 1939 my Adelaide dealer /service did an overnighter cold run around the block - they agreed it don't sound good - but hey get this - unnamed service manager when advised of the threads on this site said, well of course, Toyota are short of update injectors worldwide, therefore the stalling tactics. There you go... (100 k into the proposed 1000k re-learn, not convinced, but it worries me that after service (80k) rattle is about 50% less noisy i.e. is there an issue with 10k interval?)

          So knowing what you now know and have experienced with diesel motored Prados would you rather opt for a petrol engine.
          Iam in the market for a Grande, and most of my driving will be in the city. I have just test driven both diesel and petrol, and now after reading all the threads I am super confused.
          So basically which is better

              I reckon if your only going to be doing city driving then your not likely to experience the poor quality fuel reserves normally associated with remote area driving. Plus if you can fill up with the new BP Ultimate Diesel then you should not have any problems.

                I agree,

                The D4D is very quiet on the new Ultimate diesel, extremely economical (it seems we go for months sometimes without needing to fill it up). I can't recommend the Prado D4D more highly. That is based on my experience anyway. The Grande has Sat nav, trip computer, reverse camera, console fridge and optional suspension settings. None of which we really thought we needed but are all added bonuses (we bought it really for the added safety features for our kids).

                When we went to the Flinders Ranges, the Service Station owners used to roll their eyes whenever we pulled in because they new we weren't there to buy fuel - just to wash the windscreen.

                  Would a poll be possible to gauge the opinions of the owners of D4D's?

                  This may give an indication of the extent of the problem.

                  Possible questions:-

                  1 - I have a D4D and have not experienced the rattle
                  2 - I have a D4D, have experienced the rattle and is now fixed, and happy
                  3 - I have a D4D, have experienced the rattle, been repaired and is still noisy
                  4 - I have had ongoing problems and am at my wits end!!

                  Just a thought, questions might need to be re-worded and someone might think of more to ask.

                    That poll won't really help unless you are thinking of buying second hand, as it's dealing with history, and we already know that some early D4D's get the rattle.

                    What we have yet to see is if any later D4D's develop the rattle.

                      The saga continues. I returned my Prado again to the dealer for diesel rattle and this time they said they have received a new procedure from Toyota to check this problem.
                      Just picked up my Prado late tonight. I was told they have followed a set flow chart set out by Toyota and then did an ECU reflash and reset the codes. I was then told I have to drive it for 1000 klms for things to settle down. If I have any more problems after that, to book it in again.
                      When I queried if they dectected any noisy injectors, the answer was "no". So one of us has a hearing problem.
                      I will report back after i have clocked up 1000 klms.

                        • Re: diesel rattle in D4D Prado

                          Had an interesting conversation with a guy at my eldest's Auskick session on Sat. This guy works in the diesel injector business and knows all-too well of the problem.

                          His take on it is that the engine computer or more specifically the program that adjusts/controls the injection parameters can not vary its curve sufficiently enough to suit a wearing-in injector. As the injectors wear in, the various sensors try to detect the combustion process and fueling and then according to preset parameters the program attempts to adjust the various injection conditions (duration, timing etc). Apparently, the program has limited ability to vary the parameters and once the limits are reached (ie: injector wears beyond the program's ability to compensate), there is no more compensation. Also - apparently - the engine on light does not get turned on as the computer still thinks everything is in order.

                          New injectors need to have their code inputted into the engine's computer so the computer can map the injector's parameters to the program's curve and parameters and what parameter ranges are applicable.

                          The alarming problem is that the issue is not just related to pre-08 D4Ds....but the manufacturer tweaked the ECU program and provided a new more robust injector design from '08 onwards and it appears the problem is almost gone for those vehicles. Note....almost gone.

                          For those of you who have had the "reflash and come back in 500-1000kms time" - the computer reflash cannot alter the parameters enough - so people who get the "reflash" - only get marginally improved operational ranges for the injectors. The manuf knows this and knows in almost all cases - will not fix the problem but may extend the life of the injector. If the injector is beyond the tolerances of the reflas then the problem persists and then the only option is to replace the injector.

                          He told me a lot more info - but i wont bore you to death. I guess i take what was said as another view of the problem - albeit with some hands-on experience and knowledge.

                          Yes - bad fuel contributes to accelerated wearing of the injector and so does poor design of the injector and engine computer and fuel filter.

                          He thinks the next version of the D4D will have a brand spankin new computer program that will be able to be re-programmable - or tweakable a lot more and able to adjust operating parameters a whole lot more. When this is due he doesnt know. Maybe this will also open up opportunities for tweaking performance settings (so no longer a bolt-on or clip-on chip)....

                          cheers

                            Well, still no rattle but I'm starting to see increasing full consumption figures on the scanguage whilst driving around town, especially at around 60km/hr.

                            I used to be able to plod along at 8 or 9 litre/100km, but the guage is now showing figures of 18 - 20. Maybe the guage needs a reset? Strange indeed.

                              this is a duplicate post ok
                              guys i'm new to your forum .
                              i dont own a prado but i do have a 05 hilux sr d4d 4x4
                              my vehicle is out of warranty by 6 months and 10,000 ks
                              just recently i developed a very rough start up being dodgy injectors they did get better after getting hot.
                              i'm one of these people that has been paraniod about my fuel to the extent of carting 300 lts with me at xnas when we went western qld just to be sure i had good fuel.
                              took my truck to the dealer from which i purchased the service tean reckon i had a case so they tried to get a warranty claim even out of warranty because toyota know they have injector issues.
                              to no avail they blame dirty fuel to be the cause (crap)
                              the denso agent told me the problem is suspended moisture in the fuel that is the problem in other words straight thruogh the you beaut filter and nothing i could do about it .
                              the new injectors plus extra's 3000.00 dollars and it should not happen again cos these have a special coating inside them hooray for that ye ha.
                              anyhow this is just to let you blokes in on what i'm goin through with toyota cos ive made an official complaint against toyota on the grounds of the injectors failed well before a reasonable service time 108,000 kms through NSW FAIR TRADING its in the system
                              regards
