Questions for Model Year '2004'
My '04, Boxster base has a high pitch whistling sound (driver's side) once I get up to speed. I recently replaced the AOS as I was told it could be the culprit. The whistling sound is still there. I can even hear it with the windows up, just not as much. What else should I consider or look into?

A Porsche parts shop has a set ECU, DME, immobilizer and key from a 996.2 C4 and wondering if this will work? The ECU has the same numbers on both the Boxter and 996.
