Hello Spark, I confirm what already? said by Giarras and add this:
- If you remove the fap physically without removing it from the controller (directly or via the emulator), the risks that the control unit goes into recovery, why? the sensors in the upstream and downstream of the dpf does not detect a pressure difference, then the controller reveals that c'? an abnormality in the dpf.
In the fortuitous case that the car functions despite the removal of the dpf, the problem with you, you would almost certainly be the first regeneration.
- If you delete instead of the dpf from the ecu, but not physically from the car, this would gradually get clogged, become a plug on the drain: I'll leave you to imagine the consequences...
