Hi,
I have a 2008 D5 on a XC70. It's consuming oil since around 1~2 years (according to previous owner), but getting worse. As I'm leaving in a quite hilly place, I notice that the engine is burning lots of oil right after breaking with engine, making some thick blue smoke if breaking with engine for a considerable amount of time. That makes me thinking that the issue might not be the piston rings, but negative pressure on the engine head sucking up oil from the cilinders. Diesel consumption is awful as well and DPF is regenerating constantly, which makes sense with pressure issue...
Don't know where to go from here, would love to hear some opinions!
