In my dream world, they sit in the car, hear it immediately and say, "we'll fix it right away" and all will be well with the world.

Ya right.

the trick is to get them to sit in the car and agree theres an abnormal sound there that needs fixing. I had this old guy sit in my car the first time and needless to say all i got was some skeptical looks. then i went to another branch and had this younger guy listen. without revealing too much info at first i asked him whether he heard anything and where he thought it was coming from. and viola he actully identified the sound and the area it was coming from.. then i promptly whipped out the stack of printouots relating to this problem from this forum (and there is alot). haha i think he had not much choice but to concur with me from that point!

well then they did some mandatory sound tests (they still didnt believe it was the ecu intiially) and eventually replaced my ECU with that from a newer Z.

and the sound is absolutely and completely gone!

after my complaint he went around testing the other Zs and apparently the vast majority of 09 370zs have this problem, some louder, some softer. GTRs have it as well

all the best in getting ur problem sorted out. i know i felt immense relief when i had mine fixed.

I'm glad you got yours fixed. I seemed to have solved my problem with my high frequency sound:

I sold it. LOL!

I've missed her every day but am enjoying my new MBZ GL. I do sort of feel bad that whoever buys my used 370Z at the dealership will have to deal with that high frequency noise.

I was JUST getting ready to take her in to have this looked at when my H2 broke down and we decided to just get the new GL. Even my husband could hear the sound, so I was hopeful that someone at the dealership would be able to as well.

LOL Tam, that's how I fixed mine... I sold the car.

LOL. My husband told me it was an "expensive fix."

honestly, that's not WHY I sold the car, but it did solve my problem with it
