Nothing wrong there, that's how VW/Audi designed it. The engine can work within a specific temperature range. So owners don't get worried with a constant moving temp gauge they fixed it at 90c when it's within this design range. So for it to move to 95c is odd. Worth keeping a check on but could be down to the recent hot spell.
