    Default 407 v6 diesel issues- help

    My 2008 407 SVHDi has the dreaded engine light on and diagnosis by two reputable garages has so far been inconclusive. Yes there is a fuel problem but not clear whether its the fuel rail, control valve or diesel fuel pump? In any event to find out for sure means dismantling half the motor. I have sourced a remanufactured diesel pump overseas for A$750 + fitment another $700 but not keen until I get some certainty. Has anyone had experience , can recommend how to get to bottom of this? Appreciate input thanks.

    If it were me, I would get my hands on or visit someone with Peugeot diagnostic tools and use them before spending money on parts that may or may not be your solution. The codes they give you should give you a good indication of what the problem is or where to start.

    I agree. It isn't just the error code numbers that are needed as the extra information that can be provided only by the PSA software. Too much money is involved to put in parts speculatively.

    Do you know the codes that have been read? The Peugeot commentary on them may be useful.

    the two codes that came up were : p0082 diesel high pressure fuel pressure too low and p1351 pre/post heating relay circuit.
    I agree with both of you re having PSA software scan vehicle but would appreciate independent garage to do so as if it's the pump I can source o/seas but if Peugeot scan they want $3100 for pump. Any ideas?

    I hope I'm not all mixed up this morning - I thought P0082 refers to the valve timing control solenoid, No 2 bank, and P1351 is the glow plug relay.

    Where in Sydney are you? There are some independent garages that can help you with the right test gear. Some that come to mind are www.colliersauto.com.au/ Granville, Car Mechanic Chatswood Chatswood, and Christie's Autocare at Penrith. Revivemylion is a mobile mechanic.

    Just thought the forum should know that as a hunch given the codes indicated a fuel problem and in light of the fact that my fuel filter had just recently been replaced, I decided to change the fuel filter. No more codes, no engine light, nothing but smooth performance as before. Considering the hundreds of $$ spent in diagnosis before, I think if these codes come up the first most economical thing to do is change the fuel filter. It may not be the issue and importantly mine had been replaced just a few months before but there you have it, a simple solution.

    A long time truck driver once told me that they always look at the fuel filter/s first as it's a common cause.

    So just for interest - was the "new" filter that was the first replacement, a faulty unit, or did you find that it was full of gunk etc. when you replaced it with the second new filter?

    If it was blocked then has the tank got a load of crud in it?

    I bought a pump for a misdiagnosed 306 from england , exchange ,and found that the return freight was more than the ,holding deposit they had charged till they received the old pump ,trap for young players ,especially as it wasn't the pump that was the problem ,check the simple things first ,pugs

    No the new filter looked fine. My first thought was that after the light/codes disappeared that there might be something in the tank but the car has now run for weeks without further issue. A friend did say it was possible some micro film could develop on occasion on the filter but to date nothing conclusive.
