Terrible gas milage

So the other day after putting some gas into my car, I started the car and my check engine light came on. So I went to autozone to see what it was for and it came up as P2015 which is a problem for the intake manifold. I figured the next day I would set up an appointment with VW to get my manifold replaced since I read that's the wise thing to do.

So the next morning when I turn on my car the check engine light disappears, however I noticed since it went away the past two days I've gotten awful gas milage and nearly went through a quarter of a tank coming home and going to work.

I'm certain it has something to do with the intake manifold but would VW replace it for me even if there is no check engine light? I'm at 61k, have an extended warranty, and I heard that there is even a warranty for the exhaust manifold.

Have them check it, if its the manifold they will fix it under warranty

It does store that code, bring it in they will cover it. Depending on your mileage, it may be time for a tune up or carbon clean.

Thanks guys, noted for future reference. The CEL came back today so I guess no need to pull the code.

Any issue that triggers a CEL will store a code even if the light goes away. Hell, even your ABS tire pressure sensors store codes for low pressure when they are triggered.
