Help Urgently Needed PLEASE!!!

Discussion in 'General Motoring' started by animalambulanceman, Nov 26, 2007.

  1. Yesterday I bought a 2003 406 2.0 litre 110bhp Diesel estate in Oxfordshire-
    drove it back to London no problems and yet this morning it threw up the
    engine diagnostics warning light after about 3 miles and has not gone out all
    day.It's doing less than 25 mpg today ,when I was expecting at least 40 when
    driving on the motorway.I'm very worried as it's my work vehicle and must be
    running 24/7 and in a normal manner not drinking fuel like it is.At one point
    it seemed to stop revving over 3,000 rpm as if a limiter had cut in.Can
    anyone please suggest what to do?Money is limited and I'm not too
    mechanically minded-but can follow instructions.As my name suggests I help
    injured/sick animals and really need a reliable wagon to move them to the
    vets,and had gone to my limit budgetwise buying a suitable one,so I'm really
    in deep doo doo if I can't sort this problem quickly and cheaply.THANKS IN

    You need to get the engine fault codes read. It sounds like something has
    switched the engine management system into limp home mode. It could be
    something simple like the ECU needs a reset although I don't know how you'd
    do that. Presumably oil and water are at normal levels? Try in the Yellow
    Pages for Peugeot/Citroen specialists NOT the main dealers. The independent
    chaps are usually much cheaper and just as knowledgeable (although I have
    met one exception)

    Oh, but the rain wasn't made of water
    and the snow didn't have a place in the sun
    so we slipped behind a rainbow
    and lay there until we had done.

  3. Hi Malc,
    thanks for your advice.Apparently in July it did the same thing and had the
    ECU reset at main dealer(found out by phoning main dealer who had serviced it
    from new and at correct intervals) and can see from speedo that it was 13k
    miles ago,so must have cured it for a good while.Did not want to have to
    repeat proceedure myself every 4 months but wanted a permanant cure,hence my
    question,any ideas what could be causing the trouble and tripping the ECU?
    Kind Regards

  4. Hi,

    I had a 406 that did this. Called out the AA and he disconected the battery
    and left it for 5 mins, fault cleared and never did it again. Hope it works
    for you.

    Not sure what is causing your problems, but I have 406 saloon 2.0 hdi 110
    and I expect more like 50mpg plus on a motorway run, especially if the run
    is at a constant (legal) speed.
    25 mpg sounds really bad, my old 1991 300tdi Discovery would do more than

  6. Today I went to First Diesel Injection Services just outside Croydon and had
    it checked on a computer that they plugged in to my dashboard-showed 3
    seperate faults-the main one being with the throttle sensors which are under
    the bonnet adjacent to the throttle cable.Tony-the owners son- reset the ECU
    again after cleaning the connections and told me to go for a drive and see
    the warning light would come on again after telling me that this fault was
    probably very intermittant and replacing the throttle sensor unit would cost
    about £100 including labour and VAT. Well I've now done about 100 miles and
    the light is still out(getting 40ish /gallon in London traffic) so I'm going
    to cross my fingers and keep driving until the light comes on again and then
    will replace the sensor unit( as it may not ever happen) Tony has assured me
    that it can't do any damage to the engine and it's pointless spending the
    money when it is not essential as cleaning the contacts and resetting the ECU
    again seems to have done the trick.They only charged me a "drink" for their
    advice/time and were really helpfull -not like a big main dealer where i'd
    have been possibly taken to the cleaners-probably the advantage of going to a
    family run business?Incase anyone is interested First Diesel's phone number
    is 0208 689 6360.

    Result I'd say! And you've found an independent specialist who were cheaper
    than Peugeot.

    Not just cheaper, but also not wanting to do unnecessary work at the owner's
    expense. This really is very good to hear.

    Seconded, good find. OP; If you find a too badly injured deer, sling it my
    way ;-)
