Audi Q7 2008 3L TDI - audi q7 DPF pressure sensor - barlas

hi

i have fault codes
1) particulate filter bank1 clogged upper limit reached
2) particulate trap bank below threshold not a plausible signal
someone told me to check DPF pressure sensor and change it. when I looked I just have 1 pipe connected to it. cant find 2nd pipe coming from DPF is it possible that q7 has only one pipe connected to DPF pressure sensor?

from catalist converter only 1 pipe and one wire comes out.

Or you could do the more sensible thing and test the sensor to make sure it's working properly before you change it, which it most likely is. Far more likely is you need a new DPF which has become blocked to the point that further regenerations can no longer clear it.
