    Audi q7 3.0 tdi DPF

    Hello,
    A friend with a Q7 has problems with DPF and asked to help him with VCDS. The car enters limp mode, especially after a city walk, if it is driven manually, outside the city everything is ok. Below you have the DPF error and the filter values (14 mbar relanted pressure is ok you do not think). Engine: 3.0 TDI 171 KW year 2006. Thank you so much!

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.
