    Volkswagen Passat B6 Discussion
    If you get a check engine light and large evap leak code like I did on my 09 wagon, check to see if your gas cap wiggles a little or a lot after tightening. If so, you can order the part 1K0-201-557-A from the dealer for way less than the entire cap and swap it out in under a minute. Mine was...
