DPF regeneration

Have a Discovery 4 MY-11, TDV6 3.0 l. With DPF

Heavy oilconsumption, 1 ltr per 3500 kms. No smoke. Oil in intercooler.

Suggestion is blocked DPF.

Live values:
DPF remaining volume 0.0 ltr
DPF pressure sensor voltage 0,8 V

Tried DPF regeneration.
Engine temp 86 C
DPF Soot mass 0.0 g

Drove for more than half an hour with regeneration.
Message it was going on.
GAP support says it shuts off automatically.

Is it normal that it goes on for more than half an hour ?
The values I get, what do they mean? Discovery 4, MY2011, TDV6 Auto

Incorrect engine oil can cause a blocked DPF, do you change the oil and use the correct specification? - or rely on others to change it? It can when others can't,
It will when others won't,
It goes where others don't.

I assume the dpf has a pressure differential sensor? if so what is that reading?
