Gas cap and check engine light

Hi,
I have a 2010 2.0 with 66K miles. Recently I noticed the check engine light came on after my husband put gas in the tank. When I went to tighten the gas cap, it wouldn't tighten all the way - I can continue to turn it and it clicks, but never stops. Also, if I remove it, there's not that sound of pressure being released from the gas tank, and the engine runs a little rough.
I'm wondering if I can just get a new gas cap (and gasket?) to fix this, or do I really need to take it to the shop because of the CEL?
Thanks for any advice!
Sue

You most likely need a new gas cap. You can find someone local to clear the code for you im sure with vagcom.

Is it normal/common for a gas cap to wear out?

I wouldn't say it's normal but it does happen from time to time. Most likely from over tightening it

Sounds like a normal gas cap to me...I mean I don't twist my gas cap on until it stops turning, it just needs to click a few times. I even just went outside and gave it another turn, I don't think they tighten and stop turning like you think it should...unless you're really cranking on it maybe. I've never tightened my cap past more than a few clicks.

I also don't get the pressure release every time, so that's normal.

It's possible you just didn't tighten the gas cap enough and that's what gave you the CEL.

If you are on a budget you can buy the big O Ring seal for the gas cap from VW for alot le$$.

To test if it is your gas cap and not the N80 valve causing the problem you can spray the big O Ring seal on the gas cap with WD40 which will swell the seal slightly.

Cheers !

Update

I took the car to the dealer...turns out the check engine light was on due to an issue with the intake manifold that is covered by warranty (yay!). While they were replacing that, they cleaned carbon from the intake valves. It's running noticeably better now.

how much did they charge you for the carbon cleaning?
