Is there a way to re-calibrate the outside temperature read-out that displays in the dash ? I have had this feature in several of my vehicles in the past and they were right on. My 300C read-out is always 5 to 7 degrees higher than what it should be. I know that the dealer could probably do something, but I just hate going there if I don't have to. Know what I mean?
Anyone else have this problem? How did you resolve it?

mojoman, I will be watching responses to your query with interest. My GM cars, including the current one, have all had inaccurate exterior temperature readings. My wife's Audi is always spot on.

i had the same problem with mine. personally our thermometers are sh!t if you ask me. i took mine to the dealer because for about a week strait the only thing it read was 38 degrees when it was either way hotter, or way colder. they downloaded some new software and said it might help it, but basically the excuse they gave me was that the thermometer was only accurate once the car was moving and such. today it was a record 80 some degrees here in NY and i was driving all day long in mesh shorts and a wife beater with the windows down, and yet it still said 66! definatly not right!

in my old car, a mazda 6, the thermometer was always accurate no matter if the car was moving or idle. youd think after upgrading to a substantially nicer car i could get an accurate thermometer, but nope! if you ask me, youre better off trying to find the temperature somewhere else cause the car isnt going to tell you much!

How can you tell what is right and wrong?

But if it is supposedly 80, 66 is definitely not right

 

[300Con23s]

Mine is always 3 degrees higher. Why? I don't know.

This was a problem on the 300M too. I don't understand why they can't get this right.

What does the function in the EVIC Easter Egg (Avg and Raw Temp) do for us here. I have adjusted it attempting to make things more accurate, but it does nothing, or it returns back to what it was eventually.

You might want to check that the temp sensor is seated properly. On my dad's 5er the temp sensor got knocked by some road debris and was just ever so slightly out of position (but still properly plugged in) and it was giving me 110F when it was 80. I seated it back in and then watched the temp display drop until it hit 80.

lennoxavesosa, what the hell is a "wife beater"? That is a new one on me.

Secret knowledge = secret power

Mine was way off, and then jumped 10 degrees yesterday - but only after i hit the "secret" easter egg buttons.

 

[marlinspike]

A wife beater is a sleeveless undershirt...because that's what a stereotypical wife beater wears.

 

[rdmac]

Mine was way off. They loaded the latest SW and it is much better. I do notice it tends to be 2-3 degrees higher on general.

Now during this time of year there can be huge changes in temp from morning to afternoon. Its slowly driving me nuts. I'll drive to work in the morning and the temp will be 50 and it shows that. Then when I go home in the afternoon and its 80+ outside the temp still reads 50 (or whatever the morning temp was) and since there's tons of traffic on the way home I mostly sit aqnd crawl in traffic about 90% of the way home. So 45 minutes later when I get to those last few miles before I'm home and I'm able to pick up speed the temp will finally go up.

Quick fix. Take whatever the readout is, let's say 70 degrees and add or subtract 6. This should give you an accurate reading +/- 1 degree.

I don't understand the big deal here (other than simply that something should be accurate).

I mean, if it is chilly out, I KNOW it...if it is hot out (and here it gets bloody hot), I REALLY KNOW it (i.e. sweating my butt off). I don't need some readout telling me what I already know.

It is a nice feature on cars, but what really is the point?

Mine was like yours before they did the SW upgrade. Its much better now.

I agree 100%; that being said, now that this has been brought to my attention it is a minor irritation....I know this is not rational, I never paid attention to the reading untill this forum brought the "problem" to my attention in an earlier thread, I guess I'm wierd.

Prior to the 300 I got in March 2005, I had a 1998 Dodge ES and with an outdoor temperature read out. It was ALWAYS spot on to the temp I heard on the radio or saw on bank signs. I can't imagine that the hardware would have been changed by DC so this must be a software issue. My 300's outdoor temp is always 6-7 degrees higher than what is correct.

BTW, my build date was February 2005 so would I be wrong in assuming that the 7/27/04 fix was already included?

Mine seems to be stuck at 10 all the time. Of course that's probably what is is for real up here.

It is an important feature for me, especially when I am on a road trip. When you travel long distances and the climate control is doing it's job you can pass through a variety of different temperatures and have no idea how hot it is outside. Maybe it is only "interest factor", a bit like the saying "everybody complains about the weather but nobody does anything abou it ".

You know what? My build date was February 2005 also???? HHHMMMM!
Could this be a factor? I have never had inaccurate readings on any of my previous Chrysler or Jeep products. Why now? Maybe it was a bad batch of parts on hand at the time they built our cars. Just a thought....

Some guys mentioned that they had theirs re-programmed! What is that all about?
