It does seem a lot of oil - I'd try another Volvo dealer or Volvo specialist for their opinion or views on Volvo's clean bill of health.

I assume you've checked under the car for leaks, so the stuff is being burnt in the engine - and I bet it smokes mostly on overrun or light throttle, yes?

Would more mechanically expert readers confirm that a nicked ring or scratched bore liner would give this kind of trouble? If it is this, then it should be covered under the warranty, BUT only after you've paid to get it properly diagnosed.
