As said, you risk a massive thermal runaway in the DPF core, without EGR and doser valve, it's like starting a fire and pumping oxygen at it until it burns itself out, if the temperature gets too high, there's nothing the ECU can do to control the temperature.
Just because you have, doesn't mean you should, particularly the wet Eolys DPFs since the temperature the soot requires for light off is so low.
In terms of branded vs supermarket fuel... Again, drove my car on whatever fuel was available, never thought about worrying about what goes in the tank and again, did not have an issue.
