  1. Was not able to write down the code, but is said something like "Air Injection system bank1 and bank2)
  2. Just bought an '01 Turbo. I'm getting a Check Engine Light and diagnostics says its caused by a problem with the Air Injection System. Have done lots of research and checked the following things: Refered to illustration 108-05 of the PET for the Air Injection System diagram. The air pump (#1 in diagram) itself works fine, I can hear it sound like a vacuum cleaner during start up. Also checked the lines and there seems to be no vacuum leak anywhere. Checked the following valves by putting 12V across their terminal and I could hear each valve "click" as I did. 996 695 123 01 change over valve (#17 in diagram) 996 605 155 00 cycle valve (#44 in diagram) 996 605 165 00 change over valve (#45 in diagram) My questions now are, can I assume that the 3 valves above are OK since I could hear a "click" as I apply 12V across each valve's terminals? If the three above valves are working fine, I guess that leaves either the check valves 964 110 950 01 (#21) or the valve 996 113 257 70 (#14) to be the culprits. Is the valve 996 113 257 70 a part known to fail? What are the chances that it is the culprit? What about the check valves? Or could it be the diverter valves? Could my diverter valves be defective even if I don't hear a "honking" sound upon acceleration? Any other suggestions as to what the cause could be? Thanks. :)
