Please post your answer above...

YOU CAN SELECT MULTIPLE ANSWERS!!

No poll...

Poll available...

WOW, can that poll be anymore confusing?

it should have been ONLY about the ECU noise.

I got noises but at this point in time no ecu noise. What answer you looking for my man?

ECU or no ECU noise? How should I know? It's a high pitched noise.
How about a poll on whether or not this is a totally confusing poll?

Sad to see so many people with this issue. I've got sticky hatch and the fuel light problem though.

I think all 2009s with the "infected" ECU have the whine. If you haven't experienced it yet it's probably because you haven't driven the car enough (mine didn't start 'til around 8500 miles) or you can't hear the whine frequency.

I've always assumed it was ECU noise. It occurs when I put my foot on the gas pedal. But if I'm coasting the sound goes away. Does that sound like the ECU to everyone?

Sounds like something else. This is constant.

Hmm..So does it sound like I have a fuel injector/fuel pump problem? lol

Didn't someone complain the ECU noise came when pressing the gas pedal? Pretty sure I read this a while ago, and a few agreed with the initial poster...

Maybe. But for most people it's a constant thing.

My car used to have highpitch noise when I put my foot on the gas pedal.
same as yours. Replaced ECU and no more highpitch noise. I posted about this few month ago. Mine got fixed.
