Ok,well first problem is my HUD.When i sometimes start my car, the display on the windsheild does not get bright enough and is really really dim to a point you can't see it sometimes.And i have it set as bright as it will go. And other days it works fine.

The second problem is when i am at a stop and when i start to drive off,i hear what sounds like a water or air sound coming from the center vents. Is it something serious?? thank you for the help
