I have a 2009 with the 3.0 six. Just for kicks I started logging temps during my commute. Nothing really triggered this, the engine doesn't seem to smell hot or run hot on casual observation, I was just curious.

Outside air temp has been between 65f and 75f. The drive is 55 miles one way and consist of twisty mountain roads, highway and stop and go. The temp range I have noticed is 88c to 105c. She seems to average around 95c on the highway at 80 mph, will cool off to 88c during acceleration or a gradual climb up a hill. Will hop up to 105 to 107c during stop and go but usually drops to 99 quickly once it hits 107c.

Has anyone else bothered with this? Does it seem "normal"? Seems on the warm side to me but its the first time I have paid attention to a BMWs coolant temp.
