Hello, I have a 2007 M6 and I recently completed a spark plug change on my car. When I started it up after the change for the first time there was a high pitched sound coming from the engine bay, it sounds like back-feed through speakers but is definitely coming from the engine bay. It makes the noise for 30 seconds and then stops, the car drives normally and has no other symptoms or warning lights come on. If I turn off the engine it will not happen again until the engine cools down completely (about 4 hours). The spark plug change went smoothly and I followed the walk-through that was posted exactly. If anyone has any ideas of what it could be please let me know! It really is a horrible noise and makes me cringe everytime I start her up in the morning. Thanks
