Hi I'm new here I have a 2006 b7 s4. I only have it a few weeks and there is a slight tipping noise coming from the top of the engine it's only slight and I want to know if this is normal. I have checked the u tube videos and it's nothing like the tipping or knocking that's on these videos it's only very slight. I have only noticed it but now I can't un notice it and I'm just checking if it's normal.
