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.

My stupid service maneger didn't check it before he placed order.

Anyways...I hope it's true this time.
Dealer just gave me a rent car(sentra) and I have to wait another 1weeks to get it fixed. I will update if its fixed.


Bummer! Can you see if you can get hold of the right part number and any service bulletin that goes with it? This noise is killing me!

I havent heard it in mine but Im also a little on the bad side for hearing in certain freqs, like 6k etc but my wife hasnt said anything about a noise ye teither so hopefully I dont have it. So are they putting the ECUs with the "B" in models still being sold today or did they stop the "B" at a certain time?

My car was manufactured in 10/08 and has the "A" ecu. Uprev's software reads the number as it needs to know which ecu is being tuned. Don't have the high frequency noise (yet).

My 370z Nismo, which I bought 2 months ago started getting the noise. Right now I have 1100 miles on it and it just got louder.

I'm afraid to take it to the dealership and not have it happen. I have very bad luck when it comes to taking a car to the dealership and not being able to show them the problem.

Does anyone have any suggestions on what I need to do?

Is at a point that now all I focus on is that dam noise and it started giving me head aches.

P.s/ if anyone need contact number for department rep guy, Pm me
When you get it fixed can you please post some sort of official paper by the dealership showing what they did?

Bumblez posted in my thread about the same thing, i pmd him few days ago. Here was his post

Bumblez-
"Ok... here is update for my highpitch noise.
My dealer just change ECU which is ending with A..
That noise has been reduced a little bit but still can hear.
General service maneger was not there when I picked up my car.
I think he might say try another ECU.
Anyways... we gonna talk about this on monday.
I will ask them to change to another Z.
If they say NO?? I will hire an attorney."

SUCKS BALLS huh

Does anyone out there know a fix for this problem that effects alot of Z owners ?? can anyone solve it, 1 million dollars to the man that does

Once in a while I hear a very slight high pitch noise, but it comes from the rear of the car. This I would think is the fuel pump. I hear this in a lot of cars, mainly from the outside of the car though. This is probably because most cars have a lot more sound proofing than the Z.

Any news from anyone on this issue? I just hit 3100 miles on my '09 and have had this issue for about a month. Took it to the local dealer yesterday and only one other person could here it, and they "can't replicate the sound" and are unwilling to offer a fix. Looking for any help I can get at this point!

Drive the car with the service manager in it, and point it out to him. Or get those sound measuring devices that measures the frequency of sounds. And show him.

I thought I had this problem with my car. Turns out my wife had closed the A/C vent on the passenger door, causing a high pitched noise where the air was leaking out at the door-to-dash seal. Whew!
