Hey I had a problem with my secondary air injection valve...well, basically the code popped up on the OBD-II, and I had no clue what it was, so i went in search of some explanations. Since my Haynes manual tells me NOTHING, I checked online. Check out this site, it's not a VW site, but the pictures of the parts are the exact same.

So you can all read, and get a little education as to what this thing does in yrou car, and to where it can/could break-down.

Most likely if you take it to a Dealership, they'll just start replacing parts, and that costs money. If you have a tools set at home ,you could replace any of the parts in this whole system....save some cizzash.

What code number did the scanner give you. When you start the engine cold do you hear the SAI pump run?
