High-Pitched Frequency Update

Silver37 · 12-17-2009, 06:30 PM

The noise wasn't present in my car last Saturday until I flipped on the lights to drive in the rain. The noise came on pretty loud at that point. I'm finding that something is triggering mine to start, and once it has started it won't stop that day.

Finally, I went to Nissan dealership for replacing ECU to get fixed high pitch noise today. After the tech replaced ECU, I did test drive and that noise was still there.

WTF!!!? I've been waitng for almost 5 hours at the dealer today!!
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.

Anyways...I hope it's true this time.
Dealer just gave me a rent car(sentra) and I have to wait another 1weeks to get it fixed. I will update if its fixed.

P.s/ if anyone need contact number for department rep guy, Pm me

Bummer! Can you see if you can get hold of the right part number and any service bulletin that goes with it? This noise is killing me!

When you get it fixed can you please post some sort of official paper by the dealership showing what they did?
