Leak spotted - anyone able to identify what this is?

Hey folks, was just looking around the engine bay of my 2019 Q50 3.0t, the car has 52k miles on it. Spotted this tube with something leaking from it. Any idea what this part is? It's located on the passenger side, upper left side under the engine cover.

Update: after further research this seems to be the vacuum pump. Anyone know if this is covered under powertrain warranty?
