    Default 407 Diesel Problems Ongoing - Turbo issue

    As posted last week we've been having a few issues with my 407 Hdi. The car will just stop running and won't restart, it turns over tries to fire but won't run. Has only happened when the car was running but now won't start at all.

    It's been at my mechanic for almost 2 weeks now and finally have been given the following diagnosis.

    Diagnostic Report for:
    ADA Automotive Services.
    Peugeot 2006 407 HDi Wagon

    The DPF is logged as 47% blocked.
    There is a partial blockage from the exhaust valves to the leading edge of the DPF.

    I suspect the exhaust turbine has collapsed.
    There is excessive oil residue at the intake manifold indicative of a worn Turbo.

    Number 3 injector is over-fuelling and should be replaced.

    There is an intermittent comms error between the DME and BSI. This will take some time to diagnose.

    Only 1 DTC is permanent i.e.: 1351= Pre/post heating relay circuit. This is a common fault that relates to the Glow plugs/ relay or a potential wiring harness problem.

    Note: I suggest removal and inspection of the Turbo-charger, then removes and cleans the DPF.

    When the engine is running with little back pressure a diagnosis and direction for repair can be performed on the number 3 injector.

    The engine oil and filter must be changed before the vehicle is driven any further.


    The DPF Issue should be able to be fixed with a long run at highway speed?

    Big concern is the collapsed turbo - anyone know anything about this and how to fix? Assume its is expensive?

    The injectors look like they are about $500 each - can the ford ones be used in place of the Peugeot ones?(given that it is a ford engine)

    Any recommendation as to where i can get his fixed? Going to try Colliers as recommended but any other recommendations?

    thanks

    James

    None of that explains why it is not starting. If the turbo had failed, you would know. The noise and /or smoke is scary.

    If I were you, I would visit someone who knows the Peugeot/Citroen well.

    Note: there are two wreckers in QLD that would have used parts for your car if needed. One in Burleigh Waters (who I would recommend) and the other in Lowood (I have had no experience with this guy).

    Oil in the intake is not an indicator of turbo failure. Oil in the intake is a normal occurrence due to the crank case breather.
    47% dpf blocked indicates that the dpf if half way between the normal burn off cycles and not an indication of a problem.
    The other fault codes are common and not necessarily an indication of a problem ether.

    I think more investigation is needed.
    Is this the 140hp 2 liter hdi we're talking about?

    Denton at European Autocare in Penrith will do the job. As stated above, it's not going to be as bad as it sounds - show these results to some specialists (Denton loves to chat on the phone!) and let them put your mind at rest...

    Thanks guys,

    Spoke to Dave at Colliers and he said the same thing, so its on the back of a truck heading out there as we speak. Hopefully he'll have more luck with finding out what is wrong. And is doesn't cost me more than the car is worth ;-)

    yep Gromzx, its the 2l HDi.

    Thanks borosa, Going to give Colliers a try first and hopefully David can fix it. Thats after having a fight with AAMI roadside assistance who refused to take it to Granville, only to the nearest mechanic - useless!.

    Hi jt9876; a couple of years ago I had some problems with our 2.0 HDi engined 407 that indicated a faulty injector which are of the Siemens brand. We got 2 replacements from UK and swapped the dud 1 only to discover that the problem remained. The old 1 and 1 of the spares were tested and found to be working correctly. So if you have Siemens we have 2 good ones that will be less than new replacements.
    Our cars problems were no where near as drastic as yours. The local Peug dealer diagnosed it twice and could not find an explanation for its issue of poor low speed idling and slightly increased fuel consumption but a local freelancer with a particularly good ear and exceptional mechanical ability picked it as soon as it was proven that the injector was not at fault. I'm sure that if you have no luck in Sydney my lad up here will be able to help as he is very familiar with that engine due to its use by Fiat in the Ducato based camper-vans. Till his theory proved to be spot-on we bought a Stat write-off 307 for its engine which is currently still sitting in its engine bay.
    Feel free to contact me for any assistance you feel may be of benefit to you.

    Hi Guys,

    thanks for all the help, finally managed to get it out to Colliers on the back of a truck, took Dave all of 5 minutes to figure out that the issue was a stuffed EGR valve the was pouring exhaust into the intake as it was stuck open. $600 for the part and some labour and its as good as new, we'll it now starts and runs, took it to canberra and back this week and didn't miss a beat. Thoroughly recommend Dave, he knew what he was doing. Unlike my mechanics who had it for two weeks and threw up their hands in frustration.

    All the codes were symptomatic of an EGR Valve failure, just need to know what your looking for.

    Thanks again,

    James

    For future reference, a new EGR can be sourced out of the UK for $200 delivered.
