There is a warning 'ding' and '*' indication when the outside temperature is nearing freezing. In the Mk1 Octy this was 2degC but in the OctyII it's 4degC, first question is why?, the second question is can you change this when the warning is activated via VAG-Com?.

Isn't it a pain? 4 degrees, so what. Cost of a lot of this electronic stuff would be better spent on decent door seals etc.

My last passenger laughed when it dinged and said "The captain has just switched on the 'fasten seat belts' sign". The trouble is they build cars nowadays on the basis that 90 % of the owners could be nutters - they could well be right!

It's because when the air temperature is about 4 deg C, the ground temperature can be about zero hence ice can form.

I know, but with our kind of temperatures where it hovers around either side of 0, my dashboard thermometer changes about every hundred yards. Dodgy ice you can see and feel, black ice you can't so it doesn't matter much what the dinger tells you. It's just a mild irritation I guess - I'd rather be treated as a grown-up. [too grown up!!!]

There's a very good reason why the warning comes on at 4 degrees. It is not to warn/tell you that the temperature is 4 degrees! It warns you that there may be ice patches on the road since water freezes at 4 degrees, not zero...

Water freezes at zero. But as the car monitors the air temperature it accounts for the fact the ground is colder and so warns at four.

Intrestingly as a bizare fact for the day they can use water to protect grapes for wine from freezing. They spray water on the grapes and because when ice is forming the temperature is always 0 degrees it does not go down to minus 4 which is when the grapes are harmed.

I think you will find that normal run of the mill water freezes at 0oC not 4oC however it may still be in ice form at that temperature if it has recently got warmer. Thats the reason they set 0oC as the starting point for the positive temperature scale ,at the same point as water freezes, not just a co-incidence

You can tell the octavia is a good car when the most people can find fault with is the fact that it goes "bing" when it's cold.

Exactly, for gawd sake lighten up.

The warning sound came on at 4 degrees with my Fabia VRS and also with my new Octy. I guess having got used to the first it doesn't bother me with the second vehicle. Truth be told I quite like it, just love the fact they have a temperature gauge as our previous cars never did. It is a standing joke in our household that the main thing a new car has to have for me is a temperature gauge. Not true of course but I do like it.

I never said that the warning was an irritation far from it, however, I did ask the question as to why there was a difference between the OctyI & OctyII as to when the warning comes on and if you could change it on VAG-Com neither of which questions have been answered as yet!.

my octy 1 is at 4 degrees

why doesnt my fabia go ding:( its an elegance it should!

Yes, very true!! If that's all we could find to grumble about wouldn't we be pleased! Okay, Octy, Ding Away! [by the way, I think it said in the Book somewhere that you don't get a true reading till on the road for a few minutes]

It goes ding on the Fabia too

Have you tried driving *very* fast in icy conditions then braking hard as you go round the corner? It will probably go ding then, unless you're lucky and miss everything.

Sorry, irrelevant to the subject, but it's nearly lunch time and I'm bored here at work.

Just as a point of interest, water is densest at 4 deg C. So in a frozen pond of sufficient depth, when it is zero where the ice touches the water, it is 4 deg C at the bottom of the pond so the fish survive. If water were densest when cooler at zero, the pond would soon become a block of solid ice. As far as a liquid goes water is unusual in that it's denisty increases as the temp. decreses - from 4 to zero.

lol i think if i did that a few hedges will be my next best friends...

Looks like 4 degrees is the VW standard. My wife's Golf also dings at 4 degrees.

My Fab 1.4 mpi clock reverts to showing temperature at/up to 4 deg. (no ding, hrmmph!) but I never knew why. Seems I might have been skating on thin ice :eek: :bowdown:

Mo

ding envy :confused:

Sorry to bring 17years dead thread alive. Did anyone find the solution? Is there anyway, we can change the 4° threshold? it's really annoying.

Really good for those that might not notice it is pretty cold, and even if it is 4*oC or a bit above there might be black ice on the roads, 

as it is air temp being given as a warning not the ground / grass / road temp.

I know its good..anyw warning is good. i preferably wanna change it t 0 ° if there is any way.
