Secondary Air pump
Car makes a loud whistle noise when it is turned off sometimes. Codes show Reverse air flow detected. Is this the part that I need http://www.ecstuning.com/Audi-B5_A4-...r_pump/ES3279/
Or is there a cheaper solution?

my car did it too when the car was off. i replaced the relay that controls it and it went it away. I called my dealer and asked for the relay for this SAI pump and they knew which one right away. it is located in the plastic box under the hood on the drivers side. simple fix. good luck
