Does anyone know where the sensor for the outside temperature is?

I saw on TV that Germany's under severe weather conditions...

Sorry, I don't know where the sensor is.

It is in front of the left (driver's side) wheel well. Right behind the front airdam.

I second Nate but can't find it in the Bentley manual. I remebered mine hanging there after the wreck :( said -40 degrees once broken.

You see that blu-ish cable that connects into a ramp like tube on the lower right hand corner?? Yup, that should be the temperature sensor :)

Yup, I ran over a sharp piece of metal :rolleyes: Took out the hooks for the sensor. Had to replace the sensor, bumper cover, wheel well liner :(

Nate, did yours go -40 too?

yea, but it would warm up if I drove in water or something.

I'll leave the flamethrower test to VinceTopasBlau3 since he seems willing to show and tell with his car :) (thanx Vince)

BTW, what desert were you in @ 112?

The desert of Houston freeways in traffic on a sunny, summer afternoon. ;)

Hi Vince,

LOL!, your car's looking scary without the bumper.

And yes, very kind of you to take it apart for us http://www.plauder-smilies.de/happy/mdrmed.gif

I think mine was attached under the front of the car, on the left hand side. At least that is where I was told (last week) when BMW installed the OBC on my car.

I heard it was -45C in some places around Munich! That is cold even by Finnish standards ...

It is -16C and snowing here at the moment. Damn, I need to go and plug in my engine heater!!!

Is that -40F or -40C?

I broke the right front side of my car and found another temperature sensor. What is this one for?

Is that -40F or -40C? 40 degrees C is the same temperature (Kelvin) as 40 degrees F.

See this graphically in the photo below from the E39 thread http://www.bimmerfest.com/forums/showthread.php?t=90159

More to the point, I think the bimmer's dashboard display can be switched between C and F degrees by the BMW dealer so I think the correct answer is actually whatever you want it to be. :)

On the topic of WHERE the BRACKET is for the ambient temperature sensor, I searched Bimmerfest (where I stumbled upon this thread), I searched the Bently's, and I searched the ETK. I find plenty of diagrams of the sensor itself but none of the bracket which holds the sensor and harness connector to the underside of the front passenger side bumper. (I just now posted a separate E39 thread asking for a photograph or a diagram of that location at http://www.bimmerfest.com/forums/showthread.php?t=101296 ). Here is just one photograph from that thread.

On the topic of temperature reading, it is interesting to note that it takes a bit of time for the temperature reading to rise from -40 degrees to ambient. Unfortunately, since I had not expected such a gradual settling, I didn't document the time, but, I did happen to snap a few shots of the dash display while I was test driving the car during the few miles where the indicated temperature slowly rose to ambient (see photos below).

Does anyone know where the sensor for the outside temperature is?For the bimmerfest cross-reference record (to make it easier for others), a handful of complete photos of the temperature sensor safely ensconced in its dual brackets in front of the passenger front tire are at the E39 thread http://www.bimmerfest.com/forums/showthread.php?t=101274 (http://showthread.php/?t=101296)titled "Diagram where ambient temperature sensor assembly attaches to the E39"

As far as I know, that thread has the only set of photos on bimmerfest showing the outside air temperature sensor in situ. These photos are NOT of my bimmer (mine is missing the plate that holds the brackets that hold the temperature sensor); hence the reason for the confusion on my part (and on many others if the bimmerfest record is correct).

Seriously, you´re the perfect poster. :)

Thanks for the accolade. I've won awards in my field, and even at other marque's web sites as the poster of the year; but, being in a different field altogether, I'm a fish out of water on this site replete with afficianados. I perceive my value to be not what I know about bimmers, but what I can learn and then disseminate so others can pick up more easily where we left off than before.

Of course, it takes effort to cross reference posts; and it's problematic (links move). One frustrating problem I have in creating fully cross referenced summary posts is that a bimmerfest link to other bimmerfest threads *sometimes* works and sometimes doesn't and I don't know why.

For example, even in this thread, the same or similar link works sometimes and doesn't work other times, it seems. Does anyone know what's the secret to posting a cross reference to another thread in a different forum so that the link always works? Normally I just cut and paste (using the FireFox 1.0.4 right-click "Copy Link Location" pop-up menu) into these messages. Sometimes the link that results is usable; other times it's not.

For example, even with "automatically parse links in text" left at the default (i.e., on) value, the link to the thread http://www.bimmerfest.com/forums/showthread.php?t=101274 (http://showthread.php/?t=101296)(containing the summary photo below from a buddy's bimmer) sometimes works and sometimes does not work (yet this cross-reference photo from that same thread always seems to work). I don't know why that would be.

Shaftdrive, the cross reference is not working, because it's missing the domain name in the first part of the link.

When I go with the cursor on the (first) link you posted above, it's only showing http://showthread.php/?t=101296.

In order to make it work, it should look like this

the domain name is missing ... it's only showing http://showthread.php/?t=101296 it should look like this
http://www.bimmerfest.com/forums/showthread.php/?t=101296 See. That's the wierd part.

I cut and pasted the complete link (showing the complete domain name of www.bimmerfest.com (http://www.bimmerfest.com) in addition to the rest of the link, i.e., forums, showthread.php, ?, t=101274) into multiple cross referenced replies. Some work; some don't; same link.

Yet, as you noted, when I double-click on the pasted link in my previous message, up pops the error (in Firefox 1.0.4 on Sun Solaris 8 anyway) of http://showthread.php/?t=101296

Huh? I pasted the entire link (which had included the complete domain name and the forums and the showthread and the thread number) and I can even SEE the entire link which includes the domain name of www.bimmerfest.com (http://www.bimmerfest.com) - yet - as you and I both noted, when I double-click on the results, up pops the error "Alert: showthread.php could not be found. Please check the name and try again."

In fact, I KNOW the fully qualified link to be correct because I can manually cut and paste the link from the message above into a new blank browser window and it works just fine, every time. If I click on it, it fails (as you noted); but if I cut and paste it, it works. So, it's in the browser or web page domain - and not the link, per se.

Wierd. The domain name falls off somehow when double-clicked, even though it's there and works fine with a manual effort. As this is beginning to get off topic, maybe I should post this question to the administration sections (after searching first to see if anyone else already figured out the cause and effect and summarized completely the solution or workaround).

So that others who ask the same questions can benefit from the cross reference, there is an excellent article on repairing the E39 temperature sensor and mounting brackets with lots of pictures, part numbers, prices, etc at http://www.alisons.us/bmw/tempsensor

Does anyone know where to purchase the plug / electrical connector that plugs into the temp sensor?? Anyone know the part # ??

My temp sensor and connector were ripped off (just bare wires hanging). I have a new temp sensor, but I can't seem to find where to buy the connector!!

The above link http://www.alisons.us/bmw/tempsensor Doesn't work. Not complaining at all, this is a 2 year old thread, just wanted to mention that I did try to use all the available searches..... not sure what is kosher on here (ie, to start new thread now, or reuse old... I thought I'd try re-using an old thread)

Just reparied the ambient temp sensor on 325i 2002. It was located on the drivers side, behind the lower grill, and under the headlight assembly. Had to remove headlight assembly to get to wiring harness. The problem was the the sensor was reading -40 F.
Cause of the problem was a fraid wire. Repaired wire and sensor works fine.
