HELP REQUIRED!! Strange high pitched noise!!

HelluvaGuy · 07-18-2011, 12:40 PM

I did a quick search but the reports of the whine are cars that are running at the time. Mine was stood still on the driveway so is this still possibly the ECU? It's the first time it has done it in two years!

I had this problem. Yes it still made the noise even when sitting parked. Sometimes the noise wouldn't be there when the car was cold, but once it warmed up it returned. After just starting the car I could just push the gas just a little bit and the noise would start. Then let off the gas and it would stop. This is how mine was until the car warmed up and it would be on all the time.

I took it to two different dealers. One couldn't hear anything and said it was a mechanical noise after I told them it was an electronics noise. The second dealer ended up replacing the ECU, problem solved. On my receipt it said something about replacing the ECU according to a service bulletin. I'm fairly certain that Nissan is aware of the issue. The problem is finding a dealer that will recognize the problem.

Hope that helped.
