2008 Volkswagen Passat Komfort 4 Cyl 2.0L
During first 30 minutes of drive, it consumes gas crazy, and afterward, the consumption rate goes back to normal
I had this problem from a month ago, and when I first experienced this, I went to get wheel alignment, wheel balance, change ignition plug, fuel gauge sensor, fuel measure-related things checked. - None of these solved the problem. There is no check engine light on, or any other check signs on the dashboard.
