3 months ago my VW Touareg 2004 (1st Gen) warning appeared on the display to check the fuel cap. I did this as soon as I got the message but the message didn't go away and eventually the check engine light came on. I figured the easiest and cheapest solution would be to just replace the old gas cap that was original from the factory. Fits perfectly, after installing it I reset the vacuum code on my Touareg and it hasn't appeared since.
