Make sure you have a tech ride in the car with you and duplicate the problem. That will also help. See if the dealership can swap the ECU with one in stock and see if that fixes the noise.

Actually, when I visited my dealership at first time, I told to the service maneger " I read it on the internet"

At that time, he thought I'm crazy guy. He didn't belive that noise is coming from ECU. BUT few weeks later, he decided swap the ECU for me. He did that because there were 9 tech had ride in the car with me and they couldn't hear anything. So it was unable to duplicate the problem. Also, I went there like more then 20 times and had call him twice a week.

Every people in that dealer thought I was lying. However, I was right!!! I mean we were right!! I'm really thanks to every forum members!!

I have personally taken the TSB to them when I had some issues with the 350Z and they acted like freaking stupids. Like saying" You are not supposed to have that".

FuszNissan · 02-05-2010, 07:16 PM

Is there a TSB out on this? I haven't read the whole thread.

That stupid service maneger ordered wrong one again that time. So my car was in the shop again yesterday. This is 3rd time they replaced ECU and Finally the last one does not make noise.
If anyone has this problem, ask your service advisor to order ECU which has part number ending with A. I don't know what exactly the number is. If you have question or need service advisor's phone number, let me know.

OH MY GOD !!!!!!!!!

WOW its fixed, amazing, congratulations!!!

For real i'm happy you don't have to deal with that horrible noise anymore!!
Please get the word out as there are alot of guys on this forum with the high pitch ringing noise problem and they would die for this fix

Can't believe its fixed lol, btw does anyone know what is differend about the new ECU that makes the ringing sound go away??

I hate to bump a semi-old thread like this, but has anyone else had luck getting their ECU replaced?

I just bought my 370 a couple of weeks ago, and noticed the high pitch noise this past week. A quick Google search found this thread and a few others, and I'm fairly certain my car has the same problem.

I've got an appointment next week to check out my hatch springs, so I'll probably bring up the high pitch whine then too. Any advice for bringing this up? As in, should I go ahead and tell them what I've read online about ECUs with B serials, or just play dumb and see what they say?

My local Nissan/Infiniti dealers suck bawls. When I bring up something about TSB, they go... "What's a TSB? What's that?" Thus, I only take my car to trusty Riverside Infiniti or Performance Nissan. Seriously, most dealers suck major bawls when it comes to these kind of things.

If my dealer's service dept said "What's a TSB" to me, a customer, I'd be in the GM's office in 10 seconds with a very foul mouth!

dudafunk · 05-20-2010, 02:21 PM

Hoping Nissan comes out with a TSB on this.. I don't understand why they don't.

getmecoffee · 06-11-2010, 07:58 AM

Any news on a TSB release?

Zedliath · 08-27-2010, 12:40 PM

sorry for reviving an old post. I got my Z about 2 weeks ago and noticed the high pitch noise problem. The dude at the dealership called the "high authorities" and they have admitted the high pitch ECU problem. What's strange is that the "high authorities" have told the technician that the ECU ending with A are malfunction and the ones ending with B are the newer revised ones and should fix the problem. Currently a "B" version is ordered...and leaving me all confused about this A and B issue.

Again, sorry for bringing up this topic again

spearfish25 · 08-27-2010, 08:42 PM

FWIW, I had the high pitched noise and it's been gone for about 4 months now. My 'A' ECU must have evolved into a 'B' ECU. Weird.

ECU High pitch sound,

What's the latest on this has this been fixed!
Any bulletin numbers or factory recalls?

Thanks

Alex

Zedliath · 09-09-2010, 06:51 PM

I took my Z to the dealership. The first thing they wanted to do is to know what I'm talking about so I had the technician sat in my car and listen for the high pitch noise. The technician was not able to hear the high pitch sound, so they had their front desk lady sat in my car, and she said she was able to hear it. I told the dude something like "I read this sound is caused by the ECU, if you call your factory rep or support or something, they should be able to tell you what to do." So the technician called and the other line confirmed the issue and authorized the technician to order me a new ECU. (Upon until this point, my car was not even driven into their shop, the tech did not even open up the hood)

After exactly a week, the ECU came and I brought the car in, the tech installed the new ECU and the high pitch noise is gone.
