    Icon4 407 HDi Particle Filter Blues

    Guess what!!!!!!! I'm BAAAAACK!!! The dreaded particle filter Block light has re appeared to haunt me again on this 407 HDi 2007 model 38000kms. No short trips - shortest trip is 40 km round trip at average 80kmh speed. Time to sell it ?????

    what engine oil is in it?

    Using the wrong oil causes particle filter problems.

    The best oil for the car is Total Quartz INEO ECS.

    Shell Helix Ultra Extra is used by the Pug dealer closest to you and it should be fine too.

    The oil must have a low SAPS content to avoid particle filter trouble.

    It might also be a false alarm - trouble with the sensors in the DPF?

    Get a quote on repair before giving up on it.

    Also have a chat to Laurie Ogle Motors in Geelong - I haven't used them yet, but I know a couple of Pug owners who say they are great, and very reasonably priced.

    Default particle filter 407 hdi

    Thanks for your response simca 1100- Last oil change done by Rex Gorell franchise in Geelong. You would think / hope they used correct oil. They also performed regeneration of the filter. Will get someone else to check it out as Gorell keep telling us there is nothing wrong with anything else????? As for Laurie Ogle - had a bad experience with them some years ago with 505 hard starting - replaced something @ $ 2000 but didn't fix it. Experienced Peugeot mechanic fixed problem with some hose clamps for $100. No confidence in them.

    the forced regen is no miracle either. If the filter is completely clogged the forced regen will only partially be cleaned. Then you have two options: clean the filter manually or keep the engine during driving above 3500 rpm for more than 10 minutes and do this for a couple of days.
    And if cleaning does not do the job, you have to look for another problem. Either the pressure sensor does not do his job anymore (or badly) and the regen is started to little to late, or the cerine is not injected anymore in the diesel making the needed combustion temperature for the particles in the filter to high and not the normally 450C.
    Your dealer should hook it to the diagnostics computer and see when regen takes place. It should be between 700 and 900 km's. Anything sooner means there is a problem.
    You might also look at the egr valve and that is something you can do yourself. If you want I can give you pictures on where to find it and on how to take it of the engine. If it is clogged just clean it out as well as the emulsion tube towards the inlet collector. The egr not only recirculates the exhaust gasses it also helps the engine when the particle filter needs to be regenerated.
    Again a clogged egr means that the car is driven to slow with to low rpm's of the engine. From time to time you need to give your engine some grunt and put the accelerator all the way down and max rev it out all through the gears. Mine sees the 4500 rpm max every day and has now 140.000km's on it with no problem whatsoever on the particle filter. Even my egr valve is as clean as a whistle. I took it off 5000k ago and I had residue only 1/10 of a mm.

    Default 407 particle filter

    Thanks once again Jurgen for your advice and assistance with this problem. After the regen at dealer the diagnostic report indicated a 6% blockage which is supposed to be a very good result so I am told. I don't have the facilities to clean / remove items unfortunately, so will try another euro car specialist whom I have spoken to about the issue. I have tried to interest peugeot Aust. in remedying the problem under warranty as the vehicle was still under warranty when the issue first appeared but funny how they don't want to know about it. I will also try your suggestion re high revs driving and see what happens. Thanks again.
