Hello, esteemed automotive experts, following some diagnoses with ISTA, I found the following values:

Exhaust gas backpressure: 36mb
Exhaust temp before the catalytic converter: -50.00°C
Intake manifold pressure: 1049 mbar
DPF pressure: 57 mbar (max 36 was written)

Is the DPF clogged? Please note that all values were taken at idle (with a warm engine).

*The car has a problem, it does not enter regeneration, 2.0 diesel (driven in mixed conditions).

Thank you in advance!"

I have no info with which to compare to those numbers.

Is there a strong exhaust odor?

Does the DEF tank have fluid?

Can you initiate a DPF regeneration?

If the engine is otherwise operating with no untoward behavior can you arrange for a spirited drive to run the DPF at a higher temperature and effect a regeneration the old fashion way?
