How does Climate Control affect MPG?

mrk · 2 Dec 2009 at 13:14

Yes and thanks, I guess. Thanks for being a douche about it too (as usual I bet you're laughing with asses off in IRC about it).

I have never seen ECO mode before so was commenting from what people were saying above.

Edit*
Jez, explained it more sensibly ¬_¬

Very surprised that it makes anything like as much difference as that, what does 0.5mpg represent in terms of total %'age on a tractor like that? Must be a fair bit?

I agree with you there mate, I'll ask the Scania Workshop chaps (which is on-site at my depot) for the definitive answer.... (Will probably be told "**** knows mate!" )

If it really is 0.5MPG, i'd hope that its damn good climate for that kind of load! I am surprised that the owners of your fleet dont rip off and board over the AC button tbh

I thought your 323i had climate control?

Actually maybe it did.. you could set the temp but I thought CC did some other things as well?

Jez · 2 Dec 2009 at 16:29

CC doesnt do a lot, it just allows you to set the temperature in the car which it then automatically regulates instead of you turning red/blue dials all the time depending on how hot/cold it is outside. If it had a digital screen showing the temp rather than a series of turney dials then it had CC.

Duke · 2 Dec 2009 at 16:33

Ah ok. It only had on or off for the air con button (snow flake) which was always on.

Jez · 2 Dec 2009 at 16:34

How did you adjust the temperature of the car?

Duke · 2 Dec 2009 at 16:35

Sorry I meant it didn't have Eco mode button or anything like that for on/off, as Fox said above I think it just is the on/off button

Jez · 2 Dec 2009 at 16:36

That ice symbol button IS the eco button. But it works in reverse on BMW's for some reason.

The ice button on my car turns the A/C on, on VWs eco turns the A/C off.

Some cars like the E60 haven't got a digital screen to display the temperature but do have climate control

Indeed.... :confused:

The screen is still digital regardless of what else it displays

Doesnt make any difference at all on my cars...

no difference on my car either

There is no screen, just a twirly knob to set the temp.

Eco button is simply an AC off button. Thats it!

Thats what it does in my car...

I thought the main factor was whether the compressor was belt driven or the more eco electric compressor version, in the same way that cooling fans were originally belt driven the electric radiator fan improved engine efficiency considerably

Not on a 12v system it wouldn't be!

Some cars have an eco button instead - the function is the same, it just TURNS OFF THE AIR CONDITIONING! Thats all it does.

Econ leaves the AC on mine

Just lets the engine stop when the car does.

There is a screen, think about it

iDrive doesn't control the climate control on those models?

On E60's with the small engines and only the standard climate:

It's a temperature dial which sets the temperature the climate control is to maintain when the "Auto" button is pressed, there is no screen on the Climate Control system. It is only single zone. There is another dial where you can change the vents used (i.e. windscreen etc) manually. This overrides "Auto". There is a ********* button - light on is Air-conditioner enabled and light off is Air-conditioner disabled. There is also a "Off" button.
The iDrive only has control of the centre vents, and you chose whether the centre vents are to have the Warmer air, the Cooler air or the Medium air (overall the climate control system will still be achieving the temperature you dialled, the iDrive is just controlling which range of temperature the air hitting your face will be).
