So the general maneger called to the nissan department rep. And
They said they found the ECU which has serial number end with B, makes high pitch noise. Old ECU should be change to New one which has serial number end with A. My service maneger checked ECU's serial number on my car and it's end with B. That's why my car still make noise even though they changed to new ECU. My stupid service maneger didn't check it before he placed order.

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.:shakes head:

Hi everyone!! :icon18:My dealership just fixed high pitch noise which is coming from ECU. As you can see, I updated that dealer had replaced ECU which has serial number ending with A. But it was not. 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.:tiphat:

There better be a TSB. My dealers battle me like crazy when I bring up issues. I've just called them about the hatch spring problem and they were giving me the run-around again until they finally took down the TSB number. I don't dare try tacking the ECU sound without a TSB as they will blow that off every time I bring the car by.

If my noise was more blatant I would bring it in, but as it's slight and some of my friends don't hear it, I'm sure the dealer will be in the same boat and avoid fixing it.

Yep, the eye rolls they give when they hear that are priceless.

+1. It sucks, but that's just the way it is.

If a TSB is issued I will probably bring it in. If not, I am just going to deal. :rolleyes:

I know what it stands for lol. I was asking if there was one. Especially since he knows the whole version "A" thing.

I'm in your boat. I don't want to fight a losing battle. If there is a TSB, then at least I have a foot to stand on when I start convincing my dealership that they have to actually fix something.

Your guys dealers suck...lol

If I drive out to St. Louis will you replace my ECU? :icon18:

I don't hear the pitch but a lot of my passengers complained about it. Working at the flightline has sure taken its toll on my ears I suppose.

Come on out!

With all your tuning expertise, I am surprised your ecu is making noise.
