PO455 code; purge valve?
 

I have been reading other threads about this. Im going to try to replace my purge valve. I have an 02 B6 1.8t. I replaced the cat with a test pipe and the old exhaust with a neuspeed system. I knew I would get a code for the cat but the PO455 code is a new one that just recently showed up. I have been searching ECS TUNING site there are 2 on the site for my platform. Which one should I go with?:confused:
