I really need help I don't know much about cars but I have a 2006 audi a4 s line with 88k miles and my check engine light is on the code is po455 I'm trying to get my car to pass smog and wonder if it will pass with that on there or do I need to fix it in order to pass smog also when I put gas in my car it doesn't start on the first crank it usually starts about the second or third try sometimes first try if I'm lucky any help will be appreciated thanks

 

Sound slike the purge valve (N80 valve). This is a cheap and simple fix. Not sure if it will pass your smog screen. Where I live any CEL will cause the car to fail inspection.
