So I have had the P0411 code on my VW passat for probably a few months. About 6 months ago it came on, was on for a week, then left. Then a few months ago it came on... and did not leave. I tried resetting it just recently using the battery disconnect and discharge, but it returned after about 100 miles.
So yesterday I finally decided to diagnose it. First, I turned the car on and off and listened for the pump. I heard what sounded like the pump to me turn on and off. Great! Pulled the plastic shrouding and air ram out over the air filter box, and noticed the connection port on the side of air box closest to the front of the car was a bit loose. Pulled that off, and the gasket/rubber boot was ripped. Got under the car, found the smog pump and pulled on the hoses while the women held the one I disconnected from the air box in her hand. Sure enough, its the connection from the smog pump. Heres a picture with it disconnected and holding the ripped rubber boot
My question is, where can I buy this little guy? Do I need to buy a whole new hose? I can go to the junkyard if I must, but I would like fresh rubber for the best seal. Anybody know of a part number or name for this?
Side note: I didn't check for any leaks with the car actually running, so I don't know if this is actually the culprit, or if there is a leak in the hose somewhere else. But just the way the hose was barely held on screamed a lack of air tight to me and figured was the easiest first step to take.
