Question about 2000 Volkswagen Cabrio
1582 is likely a vacuum leak somewhere and possibly throttle body that is dirty. 1426 can be a couple of things one of which is a check valve at the fuel tank and or a cracked rubber hose from the tank to the evap. or a bad evap. They are made out of plastic and can and do crack. If the dealer cant fix this then they are really incompetent. The time to get this fixed was under warranty. Also the sensors associated with both those lights should be checked and or replaced. I prefer to test sensors rather then just randomly replace them. The car will normally run fine with these codes because it can adapt. the 1582 code can mess up the mixture though causing it to fail emissions. This is where having a second vehicle is nice. you can take the time to go over each system very carefully till you find the problem. use a vacuum pump and check the hoses and check valves etc. it can be fixed but just because some flunky passed a ASE certification does not mean he understands the physics of how it all works. Too many dealers have such mechanics, they can change a tire but have no idea how to use a scope to figure out the tough ones. They would rather sell you a new car. Find a rundown shop somewhere and ask the mechanic how he would go about fixing your problem. If he can give a good process that includes the tank the vac lines and plastic connectors and sensor testing then you probably have a good one.
