Hi everyone,

I am new guy here and someone gifted me a 2015 Volkswagen Jetta over the summer that now has 122k miles on it. When I received the car in July it only had 119k miles. I have been having the same problem since I bought it though which is everyone time I pull up to a gas station and completely refuel I have to try and get my car started about 15 times before I am able to hit the road again. It has this same problem when I refuel with more gas in the tank but it doesn't take as long to get the car back on the road. When I am driving the car between refueling it feels great and I don't have any problems. Also, my check engine light is constantly on. I went to my local autozone a month and a half ago and they scanned it and said it was just that there was a little gas leak. I also went to a mechanic and he charged me $60 just to tell me that I needed a gas fuel cap because the one I was using needed to be replaced and that was causing my problems. However, I have now bought a new fuel cap and tightened it as much as I could but the problem still persist. Does anyone know what my problem is and how to fix it
