Most of the time is when oils lick by the cover gasket to the exhaust monnyfold so fix the oil and rest of the light 🚨 code.

Can a misfire in cylinder 3 cause this issue. I have the cel for the misfire and I just got the p2096 code? I have a 13 vw jetta s and am absolutely clueless when it comes to cars.
