I have a 2000 GTI VR6. My check engine light came on and code P0442 small evap leak came up. I pulled the purge valve off near Power steering fluid reservoir and as per my mechanicís advice that with the engine off, I should not be able to blow through it. I could not blow through, so I know my purge valve is closed and works. I smoked it at that point and couldnít see any leaks.

Next, with the rear right fender wheelwell off with access to the charcoal canister, I smoked it at the fuel tank. With it completely sealed at the fuel cap opening, no smoke was escaping. I tightened the gas cap and light was still on after days of driving.

Next I replaced the gas tank cap. If the cap is the problem, How long should I have to drive for the light to go off?

Any advice would be greatly appreciated. Thanks

I had the same problem with a Honda so take into advisement, but your car has to go through three testing cycles without the code being present to turn the light off.

This took about a week of around town driving, to and from work about 15 miles each way.

The light will not go off on it's own, it has to be reset.
