Well today, after returning from the beach and seeing 110F temps after getting home we then had to go get something and when the car returned, 2002 ML500, my sister and dad went, there was a high pitched constant sound that was coming from the engine or drivers side compartment. We restarted the car and the sound came back. Anyone know what it is or what it could mean?

Did the whine go away? IIRC, it's just the injectors and it's normal. I've heard the same pitch on my ML and other MB vehicles I've driven with the same engine design.
