i recently just bought a 2000 Audi A4 Quattro
from what I can tell there is no secondary air hose for my turbo so I'm pretty sure I have a boost leak the check engine light is on. I ran down to oreillys and got these codes. I'm new to foreign cars and have no idea what I'm supposed to do. If you have any advice or suggestions or have encountered these codes before please help me.

I have the same car. your secondary air injection runs from the air box down to the SAI pump, and then to the back of the motor through the kombi valve (no turbo involved). you can duct tape the brittle plastic lines, but your SAI pump or kombi are very much suspect. you may have to be like turbo guy and take your rig to the shop, because you have a steep learning curve ahead of you, but searching this forum should help. you bought a project car, and you need to find a friend in the German car biz. No need to wish you G/L, just hard work coming - but then it will be your baby.
