Sorry to through a spanner in the works, but my XTZ doesn't do it changing up to third and never has!? The sound reminds me of selecting first on a cold day, with a cold motor. Having said that I wouldn't worry about yours particularly, I'd wait to make a judgement when its fully broken in and, not just the engine, the gearbox and particularly the clutch plates too. In fact, have you checked the clutch adjustment? Dealers don't always get it right when they assemble everything out the crate.
