2011 OM 642 Engine "Huffing" at Idle
2011 ML350 Bluetec, 187K miles. At idle the engine sounds as if it is huffing or panting. Keep up with maintenance. Performed DEF delete via software hack.
Have CEL throwing codes as seen in photos below.

Any ideas or diagnostics to start with to eliminate the panting/huffing at idle.

Thanks.

You deleted DPF via software hack and now you have codes directly associated to the DPF. Now you expect the forum to help you after deletion?

There are NO "P" codes in any CDI or Blue vehicles.

This place is a joke.
I'm surprised your bluetec lasted 187k miles. Perhaps it's time to junk it.
