    hello I am peugeot fan;- I am now begining to hate them as a result of
    the dealers they are killing this brand and the company does not seem
    to care.

    I had a 1983 205GL great car never gave trouble and now I brought a
    406LX (2001). few months back the dreaded engin management light came
    on with the reading "Anti Polluition Fault" took in to dealer could
    not diagnose but charges me in total £50 for pluging in the machine!!.
    said it could be something to do with the "secondary air intake
    system" Then I discoved that the exhaust has a bolw out changed the
    whole system including the both the O2 sensors. Now the light comes on
    and off the car runs fine???!!!??? very frustrating wonder if any one
    else has had this problem I have so changed the spark plugs oil as
    well. thanks

    Welcome to the club. I own a VW Golf 2001 with a similar problem. A 80
    euro cleaning job had no effect.
    The dealer says there's nothing wrong with the actual emissions. He is
    earnest to tell me that he can try to replace parts but that he cannot
    guarantee that this will solve the problem.
    My solution: a piece of black tape over the light.
    Fortunately there are still indicators for oil pressure and coolant
    temperature and the car runs OK in every other aspect.

    A friend of mine had the same kind of problem with his Volvo.
    My sister evenually bougth a Skoda after her Peugeot 206 frequently
    simply did not start and the dealer was not able to find the cause.
    I also heard about these kinds of problems with a Fiat Stilo.
    I think it's all about software. Microsoft is not the only one that
    makes a mess of it.
    Garage people do not understand what they are doing when dealing with
    the motor management system. They simply follow outlined routes that are
    sometimes quite irelevant.
    It's time the manufacturers find a way so that the involved risks are
    better spread over customers.
    (I had also a 1300 euro misfortune of damaged valves due to a timebelt
    problem, in spite of all prescribed maintenance.)
    I noticed that e.g. Honda and Toyota owners were more statisfied, but I
    am afraid that these kinds of problems are very common nowadays.
    For the time being, my next car will probably a Honda or a Toyota.

    I've had that happen with a Fiat Seicento, also similar on Renault
    Megane Scenic. In both cases it was a similar sensor. RPM sensor on
    the Fiat, TDC sensor on the Renault. Both do a similar job - they
    won't start as the computer can't sense what speed the engine is
    turning over at in order to engage the choke/fuel.

    Thank you for both the replies, I think this is a joke the whole point
    of having diagnostic device is to find the problem quick it obviously
    seems to be doing the opposite!!!??!!

    I think as per peugeot I thinkthe owners of models with these problems
    should get to gether a send a petition to them, might wake them up.
    wonder why they cannot make cars, which when a light comes up means
    their is something seriously wrong!!

    Hi

    I had a citroen picasso some time ago with a similar problem. Garage never
    solved it and it went away of it's own accord. There is a web site which
    discusses this problem in greater depth
    http://www.citroenpicasso.org.uk/picasso/index.php?showtopic=14336.

    Whilst it is not the same car it may have commonality of parts / design and
    there is a link halfway down the page to a technical discussion document
    from Citroen about lambda sensors.

    Hope it hels.

    Thank you for all the good advice.

    I think the problem was (hopefully) with the lambda sensors I replaced
    both when changing the exhaust system as no voltage was coming to them
    and cleared the faults. Lo behold the light came on again, so i hooked
    it up for the million time into a digagnostic machine!!! if I had gone
    to a peugeot dealer I would not have money to eat but my local garage
    is very nice did it for free?? the fault code each time before this
    was was to do with the secondary air system this time it said it was
    the new and replaced lambda sensors, while they were swiching between
    lean and rich with out a fault.....the technician said he does not
    why, so ereased the fault codes and I am running car light has not
    come on so hopefully it would have sorted it self, funny I have spent
    over £150 now ONLY for diagnoseing this problem. Shame Peugeot
    SHAME!!!!

    Had the same problem with my 307 2.0lt petrol. Turned out to be a
    faulty coil pack. Had that replaced, problem solved.

    Well the light came on again.............very very frustrating..with
    rgs to the coil pack how can I check this Dan. The fault is
    registered between 2/10 seconds after I start the engine from cold in
    the Mornings. some times it goes away when I start again or continue
    to stay on for a week or so then go off come back in the day or two.
    good if you can give me more info.

    thanks.

    Sorry Laks, I wasn't the one who found my problem, the PUG mechanic
    did. This is what they told me it was. They said it could also be
    caused by bad fuel.
    I know....frustrating, and I'm probably not making it better either!
