High-Pitched Frequency Update

BTW anyone figure out how to find out if your serial number ends with the A or the B?
From my manuals or from the dealer?

I hear the noise too. It's very subtle to me and if I were to guess off the top of my head it sounds like fuel pump whine to me.

I'm not saying it's not the ECU like you guys are saying because maybe it could be a bad fan bearing in the ECU or something wierd like that. But again to me it sounds like track cars I've heard with high flow or external fuel pumps.

I think the only way you can find out your ecu is type A or B, is go to the dealer to take the ecu out to check.
