    Smile DPF question

    Hi there, i'm relatively new here and would like to know if my dad's 1.9 CDTi 120ps 8 valve Astra H has a DPF filter on it. It is a 58 plate. Thanks for the help in advance.

    Most certainly it will do. All new diesels have them unfortunately.

    They don't do anything to aid performance either. All i know is that i can see an oxygen sensor just after the turbo before the pre-cat.

    The idea of them is to collect any soot particles from unburnt diesel from coming out the exhaust and are then burnt off at a later date.

    As they collect these particle like any mechanical filter they clog up and cause too much resistance to the airflow and reduce performance, not what we need. wonder if you can get them removed, sure i've heard you can elsewhere.

    yes this is correct they can be removed i have done it on many 1.9 cdti but the software has to be modified so it logs no error codes or does any future regenerations.

    Why are they fitted if they cause problems?
    The truth is always the truth even if you haven't realised it yet...
