Bulletin just posted - ecu noise replacement - nice work members!!!!
 

Just got a call from NISSAN service in D.C. and they said you all were right. The ECU is problematic and the corporate rep out here today verified this and they are replacing ALL nissan 370zs and inifiniti G37s ECUs now.

BRING THEM IN!

Problem Solved: Elimination of High Frequency Noise after 5 mins idle.

*************BULLETIN UPDATE**************10/28/2009****************
Ok guys. I went to pick up my car and found some information. The Bulletin on this noise is "coming" in a few days/weeks. My dealer called in a "factory rep" who immediately knew the problem and said to go ahead and order the replacement ECUs. However, the darn things are on backorder. arggggg. There is no bulletin # or info I can give you...BUT if you call your dealer service or go there, you have to ask them to call their FACTORY REP and all of them know of this problem. They will order a new part for you and when they get it will call you. I'm stuck with this noise until my part arrives.

That's all I have...spread the word. I guess this is fresh news and the ball has just started rolling with this process.

In for more, is this all or only if a tech claims you need it?

all models have the noise...all need it. Make sure your tech hears well and your general service manager looks this up..its FRESH

So is this something that dealers will start sending letters to owners about or is it more owners will have to bring the car in complaining/requesting this service? I hear it on occasion but nothing too bad. If it's something I'll have to fight with the dealer about I'll just wait.

no fighting...just go in ...tell them your buddy got it done..its a fresh bulletin and say you want it replaced. Call ahead and ask..i'm sure you'll be ok. The dealer makes money off of this stuff anyways. hehe

Oh hell yes!

HOWEVER I would like to see proof of this bulletin please before I go prancing into the service dept.

...Doesn't this mess w/ people who got tunes already??

wow i never had that problem but then again i never really listened closely to my Z because someone is either talking to me or the music is blaring out at ridiculous decibels
most probably the latter... haha. i think ill listen to my Z when its idle next time i take it for a spin.

cool at least its before we all get reflased too.

And this needs to be a sticky too.

X2. Any form of physical proof regarding a bulletin? Has anyone else confirmed this? Seems fishy.

I haven't seen any bulletin yet . OP, did they REPLACED your ECU yet? please keep us posted.

thanks

FWIW I'm going to call my service dept. today and ask if they've gotten any TSBs for the Z recently.

Hopefully this isn't a horrible trolling attempt.

14 posts. Lots of noise-threads on the first page...

I'd put money this is some 13yr old kid...

Mine doesn't have this noise. Never has.

:bs::wtf: Come on.... 'nuff said!

(sorry, there's just no "polite" way of saying that)
