I have replaced the secondary air pump in my 2000 Passat GL 4 times since I purchased it. When it fails the check engine light comes on and the error message reads "emission controls". The last time it was replaced, I was told that water had entered the pump and my pollen filter was soaked. I was asked whether I drove through deep puddles - the only explanation they had for the water. I was told that VW would not continue to replace the air pump in the future. I don't believe I drive in abnormal conditions and have not noticed that it has been raining when it failed; however, the pump has failed more frequently since I moved to Rhode Island where it rains more often. Has anyone else had this problem? Any suggestions??
Thanks for any help!
