Modern diesels can smell very peculiar when cold and the catalyst isn't up to working temperature, so I wouldn't be too concerned about that. Maybe compare it to idling when the engine is fully up to temperature after a run?
It takes only minute quantities of oil to cause smoke under hard acceleration, and as I think your car has an electronic dipstick you would need to monitor over several thousand miles to be sure.
