P0411 2001 VW Passat B5 1.8t Code P0411 Secondary air pump incorrect flow detected

Had this similar problem with my VW Beetle the plastic hose simply rubbed a small hole in it, large enough to cause a CEL and receive the error code P0411 sealed the hole protected the hose from rubbing again problem solved .. The secondary air injection pump on the B5 Passat is located under the front of the car passenger side, right under the Turbo this pump is know to collect water due to it&location it is a good idea to remove and inspect both hoses, if you notice water coming out of the pump as you remove the hose, chances are the pump is bad. My pump is good lucky for me it was a simple fix by just sealing the small hole in the hose.
