    Hi folks,

    Well i've had my 07 A4 2.0TDI 170 for a little over 2 weeks now and the problems still keep coming, Last night the engine management light came on and my vagcom came up with the following codes so i think my DPF is about to expire.

    From what I know that G450 must be replaced. I read that many 2.0 170 owners changed this sensor. What's the mileage of your vehicle?
