Black plugs and oil consumption could indicate that oil is being burned by the engine (that explains the smoke also). Possible causes are leaking valve guides/seals, piston rings, or a bad seal in the turbo. Pull off the hose to the throttle body from the intercooler and look to see if there is oil inside it, lots of oil in there means it's coming from either the turbo or the PCV system.
