Check engine light code P1494

[Matrix]

What can I do? My check engine light is going on after some days. I cut the battery, then the engine light is going of. After some times of driving, the light is still going on. i know, that 1494 means fuel leakage, but I didn´t have fuel leakage. My gas cap is always closed, and the car is only some month old, so i didn´t think, the gaket is damaged. Anybody any idea?

That is a leak detection pump fault.

Check that the soleniod on the driver seide fender is working correctly and the vacuum lines are not plugged. If that is OK, check the LDP behind the passenger side rear wheel, specifically its hoses for leaks/obstruction. Other than that, the LDP may need to be replaced.
