It's not in any of the sound menus. I can't look it up right now, but I think it's in one of the vehicle settings menus. Make sure it is not checked, since it does degrade the sound quality dramatically.

Auto volume is not "increasing the volume slider," it is compressing the dynamic range. The loud passages stay the same. Otherwise, the loud passages will be louder than desired, and the effect of ambient noise is negligible in the loud passages. It is boosting the soft passages so they can be heard more clearly over the ambient noise. Soft passages boosted + loud passages the same = diminished dynamic range.
That is why getting rid of my wind noise problem is important to me. My car is in the shop for that now. The noise is quite soft. I have to listen for it to hear it over the audio system (and it is pure white noise). So the noise itself doesn't bother me. However, it degrades the sound of my Burmester system, especially since I have the auto volume turned off. Even with the wind noise, my C300 is so quiet that I don't need the auto volume. When the noise problem is fixed, the noise floor will be that much lower.
Anyone know where the auto volume adjustment is on US models? I thought the dealer would have mentioned something about it by now since I've taken it in 3 times for this issue...
I found it on my c450. Pm if you need more help other than above.
In my car the volume automatically adjusts to uncomfortable levels when the car gains speed and becomes exceedingly quiet whenever the car is stopped. The volume will not ever remain constant, which is extremely annoying, especially in stop-and-go traffic. The variation in volume occurs regardless of whether the "Automatic Volume Adjustment" box in the vehicle settings menu is deselected.
Have any other W205 C-Class owners with the Burmeister stereo experienced this problem?
