That should be fine. Fully synthetic and diesel rated are the most important things. A 5W30 or 5W40 grade will work equally well in almost all conditions.
For extended driving in hot weather involving high speeds and/or hilly terrain, a 5W40 might offer slightly better lubrication performance and lower oil consumption than a 5W30. But to my knowledge very hot weather is rare in your part of the world, and speeds are not excessively high even on motorways, so that should not be much of an issue for your situation.
Go for it and enjoy, you may notice slightly quicker and easier cranking during cold starts in the winter with your new oil as well.
