DPF Regeneration attempt following DPF brick removal.

We are seeing more and more vehicles recently which have had their diesel particulate filters removed without their soot fill counters being reset or their ECU's being flashed with a DPF deletion file.

My question is this, have any UKAT members been able to successfully carry out a forced regeneration on any make of vehicle with the DPF's contents removed. I thought regeneration could only be possible with the "brick" being present?
