  • D4D Fuel Injector Problems

    I had the motor blow in my 2009 Prado D4D which was being driven at 90kph. The motor had only done 147k,
    been regularly serviced and well looked after. Toyota wanted 14k to put a new motor in, which I thought was a bit rich. Managed to secure a 2nd hand motor, that had done 85k, for 8k fitted. That motor came out of a 2010 model, that had a burnt out interior. I thought I was very lucky. While the motor was being fitted, another 150 series came into the yard with exactly the same problem. I thought what is going on here. That was in January 2016.
    I managed to go to Victoria, towing a 1.8t caravan ok. We have just got back from a holiday to Cairns and back, towing the van, and guess what. The exact same problem occurred 50k's out from Three Ways in the NT on the Barkley Highway. No phone reception, no towns and no motor. I managed to get the vehicle to Three Ways on 2 cylinders, and flat out at 60kph. I thought the motor is stuffed, so why not keep going. I wrote to Toyota when the first motor blew and their response was that it was out of warranty, so bad luck, we are not going to help you! We had to purchase a new vehicle in Alice Springs because no-one could fix the car quickly, and we did not have the time to wait for repairs. I might add that I did not purchase a Toyota. Could someone advise me on what to do about some sort of compensation from Toyota. These sort of things should not happen to modern vehicles.

    Ouch!

    Before buying the secondhand motor, did you have it tested? Apart from normal checking of a secondhand motor, a Prado D4D needs to have it's injectors checked and the oil pickup checked to make sure the engine is up to spec. Checking the injectors is done with software and the engine is checked after overnight so it is cold.

    If we were doing it, the secondhand engine would have a major service including a new set of injectors installed by a professional diesel mechanic. Not cheap to do that, but without it done it is just a guess how good or bad the engine is. At $8k plus a major service and injectors I think I would have gone with the $14k new motor with a warranty.

    Even so, with any Prado D4D motor, the injectors need a regular check. http://www.pradopoint.com.au/showthr...ector-readings

      The Nissan Patrol ZD30 3.0L diesel's a well known "hand grenade" engine. The 2.5L Triton diesel motor has EGR & injector issues too. Diesel Prado's post 2006. D40 Navara's are problematic, just to name a few. It's just modern diesel passenger vehicles in general... I don't think you'd buy a modern diesel these days without the issues among the models being higher than what you'd expect considering the huge outlay. The maintenance is high on the buggers and they're sensitive with their fuel quality too. And yeah those injectors at $4,000 to replace 4 is a major outlay for part of a service. But is it what it is. I've thought long and hard about buying a diesel in a year or so when I'm finished with my car and unfortunately the pros could not outweigh the cons. Quicksta8, your unfortunate story along with many others is part of the reason why I wouldn't touch one. I'm sticking with petrol so I can travel with less risk.

        Hi Photoprado,

        Do you have a procedure for said injector checking? I'm either daft (very likely) or google is letting me down bigtime on this subject

        I have a 120 which is otherwise in immaculate condition, 66,000km and serviced religiously but I have nfi how to check if the injectors are ok or not

          Hi RedHotMike,

          Worth checking, not due to km but due to age. Our 2008 had the injectors done late last year with less km on it than yours.

          There are many threads here about checking the injectors and the pickup in the sump.

          Here is the big Techstream thread, lots to read but you will get the idea: http://www.pradopoint.com.au/showthr...Bay-Techstream

          If you want to do it yourself, you need the Techstream cable and software, available on ebay. Check which version works on your windows computer, some only work on 32bit, ours is "Mini VCI Diagnostic OBD Cable for Toyota Lexus TIS Techstream 10.30.029 FW 2.0.4" which is 32/64bit.

            Hi RedHotMike, sorry to hear of your situation, possibly talk with Fair Trading in the first instance.

            The consensus is change the injectors at or near 120,000km irrespective of reading etc. I had #### change mine at 110,000km and do an air intake clean etc as well as a valve clearance check. Happy that I now have full DLC injectors fitted and should be good for another 200,000 or more. Wasn't cheap but better than D4Detonation.

              Did my 120 motor last week in a little place near Gayndar in central QLD. Luckily had phone contact and RACV Total Care looked after us. Car and Caravan coming back to Melbourne by truck at the end of the month. Mileage was at 170k but new injectors were fitted at 100 thou. Car was idling at the time at a stoplight and when I went to take off no power and smoke out the back. What a heap of shit these D4D common rail motors are. Sold an 80 petrol to buy this Prado and it was the worst decision of my life. I will never buy another diesel. Now got to try and sort out this mess.

                  Was it white smoke, by any chance? Sounds like it could be a turbo failure, not injector failure, given the injectors are only 70,000 kms old.

                  What was the diagnosis?

                    Gday all
                    in the past couple of weeks my 10/2013 Prado has started blowing black smoke when starting off in mornings and when warm and taking off from lights. My fuel economy has dropped from 9l per 100k to 11l per 100 on long drives 300km+. It has been suggested to me that I need to get the ECU re set!!? Toyota apparently can reset it at what cost I don't know. I would be interested to hear of your thoughts and recommendations, ie replace injectors, and if Toyota in Townsville has a reputable service record. Looking forward to your replys

                      Who did the injectors? Toyota, Baileys or someone else?
