Rear View Mirror
I apologize if this has been brought up before, but I couldn't find it anywhere.
Per the owner's manual, the auto dimming mirror on the Roadster has the light sensor (rear-facing) on the top lip of the mirror housing and the Coupe has the light sensor on the bottom lip of the housing (near the clown nose). However, in my Coupe, the light sensor is on the top lip. I'm trying to figure out if my car was built with the wrong mirror, or if BMW planned on having different mirrors for the Coupe and Roadster, wrote the manual that way, but then ended up just using the same mirror for both the Coupe and Roadster. I know, 1st world problem, but I'm thinking it affects the speed at which the Coupe switches to dim mode. Any insight is appreciated.

Coupe mirrors are oval shaped. Roadster mirrors are rounded/trapezoidal.

Can you include a picture of your mirror for reference?

Some coupes have the oval mirror, some have the trapezoidal mirror. My November '06 production '07 model has the oval.

Just to close this up, my question was not about the shape of the mirror, but rather the location of the rear-facing light sensor. The excerpt from the owners manual below says the Coupe has the photocell on the bottom lip of the mirror and the Roadster on the top lip. I assume this has to do with folded position of the Roadster top, where it might block the photocell if it were on the bottom of the mirror like it (is said to be) for the Coupe. In reality, it appears BMW did not make a separate mirror design for the Coupe, as my 2008 (Oct 2007 build) car has the photocell on the top lip of the mirror. I was just checking to see if anyone with a Coupe had the mirror as depicted by the language in the owners manual.

I definitely have both oval and trapezoidal autodimming mirrors in my cars. I can't check the location of the photocell right now, but the mirrors are not identical.

I have a 07 Z4MC w/ oval mirror and the sensor is on the bottom. I used a flashlight aimed at the sensor and watched the mirrors all dim, I then put my finger over the sensor and watched them un-dim. It's not too fast, maybe a couple seconds.

Same with mine.
Sounds like OP has wrong mirror, for whatever reason. Does it matter? Probably not much, if at all.
