DPF Recalibration – If you have had your DPF core removed, your Quantum dealer may be able to recalibrate your vehicle’s ECU to stop your engine going into limp-home mode, and to clear the DPF warning light. Consumers must be aware of the legal implications (as above) of this being carried out.

It is not possible to simply delete the DPF electronically or just remove the DPF unit without work on the ECU.
