Running DPF on ecu with deleted dpf
Under which engine operating conditions would you be able to leave the stock DPF in place without having regeneration cycles clear out the DPF?
Thanks
Thanks

I'm referring to the exhaust diesel catalyst.
Perhaps I should add. One of the tuners deleted dpf, egr and intake flaps and told him that it'll be ok to drive the car. This is on OM642

Is it software delete, or mechanical delete?
If you delete DPF in software, the original DPF will clog with time.
Just like software deleting flaps is not preventing from intake clogs by the gunk.
It needs to be followed by mechanical jobs.

He only had software delete. So he's driving with original DPF. My understanding is that the ECU also had a stage 1 tune upgrade making the car run slightly hotter.
now the car is frying engine coolant temp sensors and just threw some kind of turbo error code.
my guess is that the dpf is plugged and causing engine temps to go high. im also suspecting that turbo is on its way too.

When I did DPF delete on my I4 engine, I chiseled all honeycombs from DPF.
Other members report that just drilling few holes does the trick and keeps the fill in case inspector would tap it.
Now with MBUSA settlement I am bringing it back to original.
DPF replacement is part of EPA modifications, so I hope they will not look too closely to it.
