1 litre of oil per 100 miles S60 D5 185
 

No external oil leaks, 220k miles - complete cyclinder head rebuild 10k miles ago.

The only fault codes present relate to the DPF:
ECM 2A00 - Pressure sensor signal too high
ECM 2A30 - Particulate trap - Blocked
ECM Exhaust temperature - faulty signal
ECM 2BAA Particulate trap - Value


If oil were running through the Turbo - wouldn't I be getting turbo errors?
If oil were running past the piston oil rings - wouldn't I be getting misfire errors?

I'm getting repeated Soot Filter Full, Engine System Service Required and limp mode. If I accelerate beyond 2000rpm it immediately drops into limp (coinciding with the turbo 'opening' up more).

ECM - Soot mass in particulate filter 11.89g
ECM - Pressure sensor particulate filter 45 hPa

I'm using cheap 0w30 A5/B5 oil

Given I don't have any fault codes outside of the PDF is it feasible that the excessive oil consumption is wholly due to the blocked DPF ?

Remedy - checking PCV system and replacement DPF as a starting point?

cheers in advance
