P0411 Secondary Air System Incorrect Flow Detected.
 

Hey everyone, I recently got an Audi A4 1.8T and last week I finally got around to scanning my car and got the P0411 code. I heard that it's nothing to really worry about, but yesterday I was driving home and and my car just died, lost all the power, when I pressed the gas the RPMs actually went down. So I pulled over to the side, shut it off and it never started back up, so I had to get it towed. I am just wondering if that P0411 code could have anything to do with the car dying out like that and not starting back up... Any help is appreciated, thanks.

Hey, so I finally got around to scanning the car after it died and I got two codes: P0342 Camshaft Position sensor A Curcuit Low Input(Bank 1 or Single Sensor) & P0102 Mass Air Flow or Volume Airflow Sensor - Curcuit Low Input. This doesn't sound good to me at all. When I try and start the car the accessory belt is moving, but the timing belt is not. Any diagnostic suggestions or should I just get it towed to a shop?

p0411 was a broken vaccuum hose to some black pump located underneath the passenger headlight. easy fix on a hoist. hope that helps
