    DPF - diesel particulate filter Problem

    Hi

    Please could anyone here help me?

    Car is a 2012 Passat 1.9 TDI
    Mileage 191k
    Recent work replacement EGR valve 180k, new cambelt, service and brake fluid change at 191k


    Initial problem/fault
    Car would attempt to start regeneration and start the usual process of revving higher at 1000rpm
    the car would be unable to complete the regeneration and eventually the yellow DPF light would appear.

    I then look the car to VW main dealer who diagnosed a replacement DPF alongside all the sensors that are related to the DPF front an rear.

    I took it to my local garage for a replacement DPF and sensors alongside some other work as above

    Since then I am experiencing the same initial problem with no change even tho the DPF is new

    I have attached a screenshot of the soot levels etc -

    If anyone has any advice on this be very much appreciated.

    Many Thanks

    It's called the dpf merry go round , people clean or replace but don't cure the actual underlying fault of what is a flawed system anyway .

    First posts normally go in introductions else you could get a free fix and we never see you again!!!

    If you had a VW dealer diagnostic scan you should have a printout of the results, you need to post all error codes.

    That picture isn't a genuine scan?

    You need to get your motor scanned (preferably with VAG-COM\VCDS) for any error codes logged in the ecu and post them, that will save a lot of guessing and check systems out.

    Ok i will look into this and post back - that is the tool the mechanic was using tho. Let me ask him

    Its true I am looking for a fix and some hope someone here might be able to prompt with an idea that i can recommend to the mechanic so he might be able to fix.
