It's intermittent but very annoying and it happens even if the radio isn't on. I tried to reset the module by taking out Fuse 25 and it seemed to have fixed things for a day but now the noise is back.

Does anyone have any suggestions?

Thanks,

Pat

Could be water ingress issue on the back of the CIU.
Did it rain recently there?
Another way to test is to remove the fuse for the CIU, and does the sound still happen? If it does, the it might be the amplifier inside the rear deck lid.

sorry, not very handy when it comes to cars ... is the fuse for the CIU the same fuse I took out and put back in ie. Fuse 25?

Also, how do I access the amplifier in the rear deck lid so I can check it out... I'm always taking in and out large hockey bags from my trunk, maybe that did something?

Did you ever figure out what was causing this?
