High Pitch Noise Fixed!!!!!
 

Thanks to the help of bumblez and his dealer in richmond I'm finally getting rid of the dreaded high pitch ECU noise that has driven me crazy the past couple of months. The first time i brought the car in nobody could hear the sound but me and the dealership acted like i was just hearing things. I told them that I was 100% positive the sound was there as I am an air traffic controller and have my hearing tested annually. After that unsuccessfull attempt I PM'd bumblez which led to me calling his dealership and speaking with the gentlemen that solved the issue for him. They were AWESOME!! and explained to me how Nissan knows about the issue yet won't issue a TSB because so few people are actually capable of hearing the sound. They gave me the part number and told me to tell my dealership that Nissan is aware of the problem and on the Nissan Tech Line they acknowledge the issue and list the fix. It has something to do with the capasitors and ECU that causes this head splitting noise to occur. Even with all this info that i brought to the table on my second venture to the dealership they stated that the problem need to be reciprocated and they needed to hear it. This is where the Richmond dealership gave me the best tip. They told me to have a young female, if available, that works at the my dealership to sit in the car because it seems they hear the sound instantly and better then most males. After about 2 or 3 guys said they couldn't hear the sound I had them bring a young lady that worked in the service dept. to sit in my car. Immediatley she confirmed the noise and it was only then that my dealership searched their Tech Line and found all the information that I had already given them. Thanks bumblez and thank your guy the next time you see him!!!!:tup:

hmmm interesting, since most guys cant hear it, it mean the noise must sound like our wives complaining again and we are just used to tuning it out. lol. Glad you got it fixed.

I'm really happy that u solved this problem!!:icon18:

Most goys can hear it? You mean Jews can't? Oy vay. :happydance:

I guess Ill go edit that real quick. Didnt even know that was a word. Man I screwed that whole post up. I was drunk typing without being drunk. Kinda funny tho.

Might need to get my eyes checked out! huh?

:bowrofl::bowrofl:

If i hear it on my 2010 model would they fix it? or is Nissan only acknowledging 2009 models?

Congrats, once I got it fixed EVERYTHING WAS BETTER.

i believe issue is solved on 2010 models
 

i believe issue is solved on 2010 models. So it won't happen to you. But if it does, don't wait as long as i did and make the dealership fix it

they said they fixed it on the 2010s but i still hear it... or am i just "hearing" it because im actually looking for the sound?? oh god... i.. think im going crazy...

The real issue here is why was it "only then that my dealership searched their Tech Line and found all the information that I had already given them"? Why couldn't they simply have confirmed what you had already given them and take it at face value that you could hear the noise?

Exactly. I am about to go to get mine fixed at the dealership. Will post how it goes in a few days.

Whine
 

BumbleZ or CubaRican,
Do either of you know the part # for the fix? My dealer is either ignorant of the issue or playing ignorant. I have to blast music just to drown out that whine...not a good solution.

^ ditto here, my dealer is being a pain in the ***. either of you PM me please?

I thought the same thing. I guess it just comes down to how they want to handle it as there are certain procedures they are supposed to follow. One of them being hearing the problem themselves. The ECM is $1200 part without installation. The real issue is with NISSAN. They should have put out a TSB on this but they figure to save money because people with sub par hearing don't know the problem exhist. Not until they drive with a passanger one day who goes madd because of the piercing sound pounding their skull! LOL
