Hey everyone, I'm new to this forum as I just bought my first Mercedes (2004 E55 AMG) a couple weeks ago.
I've been trying to figure out this whining noise that I can't pinpoint but does not really sound like it's coming from the front of the vehicle (engine). I could be wrong but it sounds like its from the middle or rear.
This whine happens during hard acceleration like over 60% input and gets louder the further I put the pedal down.
At first I thought it may be low diff fluid as the car has 125k miles and I didn't get a service record for that so I replaced the fluid and no luck.
It's so loud that if you're driving behind it you can hear it from a couple hundred of feet away
Any advice would be greatly appreciated.

Thanks

You should move your post into the W211 AMG sub-forum to receive lots of TLC from the gear heads there.
