  • My car is not old enough to smoke

    I've read about DPF burns and thought these only happen on long runs, however, on two recent local runs around town my car has blown what I would consider excessive smoke from out the exhaust. I am not a lead foot and generally drive conservatively around town not using too much throttle but on these occasions I have been pulling away from lights or a road intersection and big clouds of smoke can be seen swirling behind me as I look in the rear view mirror, is this normal? Only last week I did a 600km road trip, I would have thought that would have cleared out the crap in the system. This week I've only used the car twice for shopping trips. I welcome any comments.

    They will burn as soon as it hits its perceived accumulation level only. Doesn’t matter if on highway or putting around town. A long run will not trigger a burn either it’s all about perceived accumulation.

    First thing you need to do is clean the 5th injector and force a regen if smoke is excessive. If accumulation level hasn’t come down enough force another, this one will be hotter.

    just note to is drive it harder when under regen it will burn better. I flog the fortuner when under regen, lots of throttle and boost.

      Definitely get it to Toyota ASAP.
      They will likely do a manual burn and squirt a can of DPF cleaner in. Not sure how much this actually helps, but most importantly you'll have started a record of DPF issues with them, all the better should it get worse in the future. The 5th injector clean really looks like a big part of the solution, but I personally wouldn't be doing that before talking to Toyota whilst still under warranty, don't want to give them any excuses, what do you think Luke?

      My DPF is still fine at 40k, but my friends 2.8 Prado at 40k has just started blowing smoke

        Unless you are a qualified or licensed mechanic it’s honestly better to not do it whilst under warranty.
        If a licensed mechanic in Nsw does clean the 5th injector it’s no issue. You don’t even have to take it to Toyota for services to keep your standard warranty.
        Other states don’t have same licence legislation as NSW when it comes to people working on your car.

      +1 for not touching the 5th injector. i think mine is just starting to go downhill ( 30,000klm ) and i was going to clean it myself , then decided not to just in case they accuse me of buggering it. If the DPF fails then so be it ( while under warranty )

        I have (Toyota) thoughts as mentioned above. The car isn't two years old yet and only done 28,000 kms so I think it will become their problem and not mine. Thanks for your help.

          Here's an update on my smoking car. Having done 4 DPF's in one day it was time to take it to Toyota, and what did they do? As far as I can see nothing more than getting out the Dyson and giving it a quick vacuum. They tell me they cleaned out the DPF unit (vacuum) did a PDF burn (my car does these regularly, just like we fart) and road tested it. Apparently my ECU is up to date, which is pleasing. One thing I do have is paperwork confirming the car has been in for a check up in this regard so if I get excessive DPF burns in the future I have something to refer back to. They adamantly refused to replace the DPF, apparently they cost about $5,000 and Toyota can't afford to keep doing this, I was told.

              Basically most people are still under warranty

            At the moment, Toyota can't sort out the DPF issues, even with all their techs, knowledge, machinery & money at their disposal. So I doubt any other organisation can come up with a solution. But hey, at least you got shove an ad into the forum

              Yeh, I saw the previous post but I would go to a tyre company to get tyres, not for mechanical issues, I think there are companies that are specialists in their field which I would go to first.

                  Hey Cookie, the burns lasted about 20 - 30 seconds each time. Most times I tried to burn them out by putting the power on and accelerating, which seemed to work. Large plumes of grey / white smoke came out of the exhaust, which is a bit embarrassing in a newish car and would have been an issue if Mr Plod was following me (I can't choose when my car wants to fart officer) but all appears fixed now as I had Toyota do a clean out. Mind you, I haven't done a lot of k's since they did this so I do not know if the problem has been fixed or if it will reoccur.

                    How long is a normal burn? I thought I read somewhere it lasted longer.
