Codes, codes, codes. Any help divining the truth?

I know my SAIP is completely kaput. Could that be causing these other errors, or is my EGT sensor, and maybe the O2 sensor, really toast? Anybody know how hard these are to R&R?

Thanks!

They are all fairly easy to access and replace if you have the correct tools

I'd definitely replace the pump, clear all codes, and go from there first. Genuinevwaudiparts.com has the SAP, also someone, just recently, was selling one in the classified (I think they were from the S4 forum) Some have also rebuilt the pump themselves. I plan to do this when my pump goes. SAP then O2's then EGT's. Let me know if you need any help.

Dude want to swap SAIP's? If mine works....

You pay me for the rebuild, like $250 or something?

I'm not sure if my entire system is working, so it may be worth a shot to see if it works in yours.

I could do this this weekend, sunday, if interested?

Also, it sounds like your EGT sensors are dying - easy fix.
