Hi All - I'm getting a "Loose Gas Cap" error code on my 2006 Audi A4, which is causing the check engine light to go on. The Gas cap is definitely on there tightly. I've had the code cleared and have been watching how tightly I am putting back the gas cap and the code keeps showing up ...

I'm not hearing any sounds from the gas pump ... Any other ideas on what could be causing the error code? Maybe a gas leak in the system?
