Information Temperature display bug

I was driving to work this morning and noticed the temperature dropping from -4 to -5 as I got out into the country lanes nearby. At this point the "snowflake" symbol was visible but as soon as it dropped to -5.5, the "snowflake" symbol disappeared!

As soon as the temp rose above -5.5, the snowflake appeared again... It looks like the software can't differentiate between + and - figures so thinks that it's above 5 degrees and turns it off (or maybe in Germany ice doesn't form below -5 Degrees Celsius!).
 
Funnily enough my VW Beetle has a bug with the snowflake too, albeit not quite as you describe.
 
Mine did the same thing this morning. I put it down to the fact that if it was -6 I didn't really need a Snowflake symbol to know it was frickin freezing! ;)

I did laugh when the temp rose to -4 and the Snowflake re-appeared.

It all adds to the character. :D
 
The owner's manual states that the snowflake symbol appears at temperatures between +5 and -5 degrees C. "This is to warn the driver that ther is risk of ice on the road" :D
I don't know what is supposed to happen below -5 :confused:

Enjoy the cold weather ;)
 
I miss the sound on the A2 that the snowflake symbol makes on the VW Golf I Had. It was a nice quiet calm sound, kind of like the seatbelt noise on a plane, not like the horrible frightening fuel low noise the audi makes!
 
Below -5, the snowflake disappears again - I know this as an earthing fault caused my ambient temperature readout to plummet to -12 on even the warmest days a few months back!

Cheers,

I see the snowflake play on the display daily over here.:D Below -5 degrees, it disappears. I think they thought you don't need the flake to warn you that the road is frozen below that temperature, and you would certainly feel that.
 
It's not as mad as it sounds. Black Ice, which is the ice that is particularly hazardous to us drivers due to its clear appearance, can form in the absence of snow and rain, is most likely to form down to a temperature of -5C - this is from water in the air freezing on the surface of the tarmac. Below that, you'll get the formation of "snow ice" -which as Trex points out, you're much more likely to spot as it'll more likely be snowing all around you!
 
makes sense to me... but then, you need to watch below about -15 or so, as then the motorways turn to skating rinks and below -20 it's fine again.

It's too warm here, anyway, only -3; I want serious cold so I can get the pics on the ice done!

They're saying parts of the UK will see -10C tonight. Global Warming in full efffect I see!

It was seriously slipperly 2 mornings ago on an untreated backroad here -there was about 2mm of snow on the road and me in my 215 summer tyres - the traction control was having a work out that's for sure, and the ABS.
 
It's very simple. When the road SURFACE temperature is around 0 degrees, it's usually the most slippery, no matter what the air temperature is. Since the air temperature is the only temperature that is practically measurable in moving car, the snow flake is there between +5 and -5.
What I would like to see in future passenger cars, is a traction measurement wheel that constantly measures the traction as you drive, to alert the driver when traction is limited. The technology is available , since it's used in salt- and gritting vehicles already. And at airports to measure the traction on the runways. -31 degress celcius yesterday morning...
