F430: What is that little thing underneath the driver's sideview mirror?

thermometer? its on the 360 as well

 

It is the outside temperature sensor.

 

Here are a couple of pictures so, others will know what you are talking about.

EDIT: I never knew what it was before now. My guess was that it had someting to do with the alarm.

It is the infared sensor for the door locks / alarm

 

Nope. That is right on the dash in the middle.

 

just a wild guess as my '97 355 has the same tities.

could it be the lower pivot for the mirrors?

On the 360, it is outside temp sensor. I guess it's the same thing on the 430.

 

it is on the 355 as well. i have always herd it was the temperature sensor.

 

Okay, I'll throw a monkey wrench into the mix...

Are the door lock remotes even infrared? That seems highly unlikely. They should be RF.

The thing on the dash is for what? My guess is automatic headlight sensor.

 

I think you might be right Dave.
Does anyone know if 360's or F430's have automatic headlights where they turn on when it gets dark outside?

 

The 360 does not, I don't believe the 430 does either.

What is the temperature sensor used for? The climate control? There is no outside temp gauge is there?

 

Yes, there is an outside temp gauge in the 360. As per the MANUAL, its the temp sensor. I hope this settles it.

The one on the dash has something to do with the A/C or the alarm.

 

there is no outside temp gauge in a 355 but it has the nipple under the wing mirror?

 

It is a special feature designed to get manic obsessives to make new friends by discussing it on internet forums!

 

Yes, the F430 does have an outside temp gauge on the dash. I'm new here & so is my Yellow/Black F430

 

My 95 355 has the same little nub, but doesn't have factory keyless entry, no inside temp readout, and certainly no auto headlight feature. Can someone clear this up? There has to be a F-tech out there somewhere that can tell us, I have always been curious about this.

 

Show us a picture of what you are talking about. Are you talking about a sensor or a guage on the dash?

Would love to see pictures of your yellow/black F430. Please post some.

 

the nub on the mirror is the temp sensor. you can read the outside temp by pressing "mode" to the left of the steering. the circle on the top of the dash, according to the owners manual is the "sun radiation sensor" for the AC system.
