Well i am a first time audi owner and have no idea what's happening when i hear these weird noises coming from my car.

Noises i hear when my Audi A4 is idle, is a loud ticking noise from when i start the car and while i'm idle at a red light. The second noise comes from when i'm stepping on the gas pedal either on just "D" or "S". This noise is unfamiliar because i don't know how to describe it. If i were to take a guess, it sounds like a part is making a nose that is grinding against something to make some type of hissing noise.

So i have this service maintenance coming up and told them about the problem, and was told they would take a look at it.

Would this stuff be covered under my warranty?
