I have a 2000 Passat (1.8T), and I recently had this code (P0411). First thing I did was to clean the mass airflow sensor (MAF) and reset the code by disconnecting the battery. Unfortunately, the code came back. It also came back with P1426. It ended up being the purge valve ($60 at ECSTuning, $140 at the dealer...I went with ECSTuning). Before you drop money on the part, inspect all of the hoses to ensure they are not cracked or torn.

P0411 Secondary Air Injection System Incorrect Flow Detected
p0411 is a generic code, probably a vacume leak,vacume hose broken check this first, check the air pump turn on the car but it needs to be cold, you should hear a high pitched whine, this is the air pump running,there are 2 hoses one suction one blowing thishose should be going from the air pump to the air cleaner disconnect that and see what the volume is should be pretty strong.
But mostly you probably have a broken vacume line somewhere

Even simpler than that, it could just be the two braided vacuum lines, one leads to the intake diaphram, usual culprit. They are mounted on driver side, back towards firewall.

SOURCE: The check engine light has be checked several-P0411 error.

If were to venture a guess(and i am) it is either a valve or something that regulates either the rate of fresh air or the direction of it. Check the sec air valve or whatever VW calls it for blockage or sticking.

It is very likely this code is coming up because of the vacuum hose as well.
