Sounds normal to me. Its how these engines sound. D5's aren't the quietest or most refined, but they're a very strong engines.

Just one thing I noticed. The coolant is the wrong colour. It should be green, not red. Maybe sometime in the future, flush the old coolant out and replace it with genuine coolant from Volvo. Also the power steering fluid is a tad low. Buy some CHF 11S fluid to top it up. That's also green.
