    Unless someone's skimped on servicing won't it still be under warranty?

    Take her out on the motor-way and drive the living shyte out of her - redden her, having let her warm up properly first. Was she doing a heap of short journeys lately?

    If this doesn't clear the problem it could be a failed sensor or big bill. My pal in Galway got hit with €1,250 for a failed DPF in a Saab (Opel Vectra) a couple of weeks ago.

    OK, sorry about that. It sounds the regen can't be triggered by the ECU or by the "normal" fixes.

    Can your mechanic's code-reader / diagnostic system interrogate the ECU for faults even if it can't switch on the regen cycle?

    Those DPF's are a bummer, but needed for the Euro V emissions I think so you can't yank them out or it'll be a fail come NCT-time.

    On the 407 2.0 hdi's (Which i think is the same engine) the dpf usally
    blocks up around 120k miles.
    As mathepac has said it could be one of the different sensors used to monitor the condition of the dpf e.g. filter load..differential pressure..etc.

    Most garages with diagnostic equipment like snapon...launch etc should be able to check this for you and save you some money instead of getting ripped off at the main stealers.....:)

    Mazda engine is not a PSA/Ford unit, it is built inhouse. DPFs are a curse.

    And the problems with the Mazda diesel engine have dropped Mazda from one of the top 5 reliable car makes to one of the bottom five. Avoid, avoid, avoid!!!

    Aye and as you said, the DMF is a disaster waiting to happen on most modern diesel cars. A neighbour just spent €2,500 for a DMF fix (including TB and full service) on his 3 year old Korean car, just out of warranty.

    Painful money to spend on such a crap car...

    Modern diesels are far too complex for their own good.

    That said, with the new trend of direct injection and turbocharging, modern petrol engines are slowly becoming very complex too.

    I really am not keen on the current trend of downsizing.

    Perhaps I am backward and don't like seeing progress where you no longer need your own oil well to have something with decent power but my fear, which I feel is justified after what has happened with modern diesels, is that any fuel savings will be wiped out by the added costs of fixing them when they go wrong, which will get more and more common as petrol engines become increasingly complex.

    Tell me about it, just had mine replaced 3 weeks ago, my wallet is €900 lighter. The even worse thing is that I am planning on changing in the next couple of months.

    Just a shot in the dark,

    Why not pull out the DPF and install this small box of tricks:

    http://cgi.ebay.ie/FAP-DPF-OFF-DIESEL-PARTICULATE-FILTER-EMULATOR-/320559713381?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item4aa2d90c65#ht_943wt_1139

    I've no idea if it works or not, but it claims that you will never have DPF faults again (as its not there:D)
