  1. Hi I'm also writing from Denmark Blocking the 5th injector would not be such a great idea. Without the 5th injector the DPF cannot regenerate properly. But from what I know and heard the DPF is worn. Has your car ever gotten a DPF? My car also has this problem but I have just driven it like that .
  2. Okay keep disagreeing with my true FACTS. I'm telling the truth and I'm not talking out of my imagination. I got all of this info from a Toyota mechanic that knows about these engines a million times better than any of you. How are any of you gonna say that the Toyota mechanics words are not true and how much experience have you guys???? I own a Avensis that has the same problem and I have experienced this. My car has 300.000 km on it and has never gotten a new DPF. What else could be causing the smoke?????? If it was anything else it would have caused a check engine light. A worn DPF cannot cause a check engine light because it is still free flowing. And yes diesel can vaporize Stivino. How would you not know that??? Blue smoke would have been oil and it’s not burning any oil. The ceramic filter looks like a honeycomb structure. This structure is covered with a layer of chemical catalyst that contains small amounts of precious metal, usually platinum or palladium, that interact with and oxidize pollutants in the exhaust stream (CO and unburned HCs), thereby reducing poisonous emissions. Let me ask how much experience guys have with these engines???
  3. It is by no means impossible. DPF filters become worn and looses their catalyst over time and by the milage. The job of the fifth injector is to get the diesel it sprays in the DPF to react with catalyst in the DPF to reduce the amount of NOx. But when the DPF is worn out and there is no more catalyst in the DPF all the diesel that is sprayed in the DPF becomes steam due to the diesel hits the warm DPF. And thats why the car only smokes when the engine is warm. Toyota never planned a service to replace the DPF at a certain milage. While other makers recommended that the DPF should be replaced at a certain milage.
  4. Just a quick add. The ECU update that Toyota made does not work because this issue is not ECU based but hardware based.
  5. If a Toyota AD series engine smokes blue smoke. Short answer the DPF is faulty. People tend to see this issue when their car has driven over 150000km. Many think this issue comes from sensors and the 5th injector which reacts with the catalyst in the DPF. Replacing the 5th injector does help until the ECU learns how to use it again. That takes around 50km, but when the ECU learns how to use it again. It does the job totally correctly. But the only reason why the car is smoking is because of a worn out DPF. The diesel that the 5th injector is spraying helps to react with the catalyst in the DPF. But when there is no catalyst left in the DPF and the 5th sprayes diesel. The diesel hits the warmed DPF and just burns and becomes steam. Many people think this it smoke, but it's not. It's steam. Other makers such as Mercedes and BMW claimed that the DPF should be replaced every 100000km while Toyota never claimed that to their cars so theese eninges run with faulty DPF and not get a Check Engine Light. So thats why the "smoke" happens.
  6. When i replaced the 5th injector it did not smoke the next 50 km. But it started smokin again for me
  7. Yes you need a Toyota/Lexus original dpf to fix this issue. In cold weather you can easily see the smoke while in the summer you don't see it very much. Thats because steam is easier to see in cold weather. But in the summer you car is still smoking and you can tell by looking at your mpg which should be very low if you have this problem. But don't take my word 100%. Be sure before changing the dpf and you can ask your dealer to see what they recommend.
  8. I talked to a Toyota mechanic about this smoke. There was a update to fix this but it did not work until they found out it's the dpf and not the ECU. He said it's the dpf because when the car smokes there is no more catalyst in the dpf to burn. So when the car regenerates the diesel that gets sprayed in the dpf and the diesel evaporates and thats where the blue smoke is coming from. Also the cars only smoke when they get up to temperature and the ECU is thinking the dpf is ready to regenerate but there is no more catalyst in the dpf so the diesel just everporates. Other automakers said the dpf should be changed every 130000km while Toyota never said that so these D4D go to around 200000km and the dpf is worn out. Many people has tried a aftermarket dpf but it still smoked and it has to be a oem one. He also said if the 5th injector is clogged it's also bad and there is a small chance that it's not the dpf

  10. I also have this problem and it's really common on these engines. When i had my Avensis T25 removing the DPF was eaiser when the car was on a lift. I'm not sure but I think it's impossible to remove it without the car on a lift. This shows how to clean it in the car
  11. Yeah. I have also trying to find a fix for this in 1.5 years but still no fix. Many people have fix this in different ways such as replacing engine sensors and disconnecting the battery for 15 min and the one you told about resetting the DPF. This guy with a Lexus IS220D with the same AD series engine did pretty much the same as you told and fixed: https://www.lexusownersclub.co.uk/forum/topic/107523-potential-fix-for-is220d-white-smoke-smells-of-diesel-poor-mpg/
  12. DId replacing the alternator fix the issue? I also had one that went out recently which is common for these engines.
  13. If it smokes it's not normal. These engines should go around 18km/1L. If you have been following us in this chat you will know me and 3 people replaced the 5th injector and it made no difference. Of course the car ran better but the smoke was still there. I have been driving my 1adftv with the same issue for 1 year now.
  14. Ok. Keep us updated. Btw my car still has thr issue
  15. My car still smokes but I don't care that much more. The MPG has gone up and it smokes alot less. Eventaully if anyone finds a fix for this I would fix it too. But for now I guess I just have to live with it.
