DPF Differential Pressure

[miguegallo88]

Had anyone had a P2002 (Backpressure below threshold) code?
What is the differential pressure supposed to be? (in mmHg)

Is this an exhaust thing?

Yes, the DPF (diesel particulate filter) is on the exhaust of all modern diesels.

I haven’t had any check engine lights so I can’t help you there. But the dpf should be covered under the emissions part of your warranty depending on mileage of course.
