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!!!!
