    Lightbulb Passat B6 2.0TDI DPF test / time to repair?

    Hi all!

    Tested a little bit my Passat B6, 2.0TDI BMP for DPF measures. No fault codes, but Pressure Difference at idle = 7.65 (in some moments go up to aprox. 10).

    Pressure Difference in driving mode:
    2000rpm ~50,
    3000rpm ~100,
    4000rpm ~199.

    Pressure Difference Offset stays -12.75 all the time (negative is ok?).

    DPF Load Coeff: 0.0%
    DPF Carbon Mass: 108.0 (max value 60gr)
    Carbon Mass Learned: 0.0%.

    The car have 340 000km (212 500miles) on clock.

    Is it time to clean/change/remove DPF? Don't want wait till LIMP mode etc.

    Thanks for technical help! Cheers!

    Hi there,

    Posting a complete vehicle Auto-Scan would be helpful

    "DPF Carbon Mass: 108.0 (max value 60gr)"

    I think this (above) says it all..... almost double the "max value"? - with the high mileage, I would look into cleaning the DPF.

    Hope this helps,
