We have a Climatronic system on ours though.
I'm not sure where my patience comes from!
I don't understand what you're getting at. Why would the cooling function be relevant?

If you remember, I was suggesting a sequence near the end of journey that might help to reduce moisture in the air conditioning system, to avoid undue misting when the engine is next started.[/quote]
Yes, and I've taken it into account, but I'm not particularly concerned by misting.
Although, the penny's just dropped and you're relating the necessity of demisting the windscreen to my turning the heater off to speed up warming.

Yes, and ...

Yup, that's the economy mode - in the past the button was even labelled "Econ"
Oh, I see. I was simply a bit confused by Gareth speaking of an "econ" mode when there's no econ button. I'm afraid I've never linked the AC to an econ function. Even on our '06 Galaxy (thankfully retired), the econ mode just meant the AC was switched on and off as necessary as opposed to having it running all the time.

About 1.5 mpg in my old Octavia 1.8T (petrol)
Well, 1.5 mpg isn't much when the car is currently underperforming by about 25 mpg, according to official figures, and underperforming by about 10 mpg according to realistic figures predicted by me.

Not any more, it isn't. Modern refrigerants don't dry out seals like the old stuff used to do.
I didn't know that! Perhaps I'll switch off the AC for a trip and see what happens.

The difference will be marginal. Diesels just take longer to warm up, period.
It did make a difference when the temperatures plummeted to -8.5. I had the oil temperature reading something within 5 miles, whereas when it was -2 and I left the heating on, it took approximately the same amount of time for the oil temperature to read something...
Mr Cholmondeley-Warner wrote:TheInsanity1234 wrote:Eh, well. I'm not bothered by economy anyway, it's mainly because I tend to rev the engine a lot, and so having an engine up to temperature is ideal for me.
Well learn to drive sensibly until the engine is warm (and that doesn't just mean the temperature gauge - the oil will take significantly longer to warm up).
The oil doesn't reach full operating temperature until after about 8 or so miles of normal driving (including full use of rev range). I tried once, to keep revs under 2000 rpm until the oil was at operating temperature, and it wasn't reading 90 until I was within a couple of miles of my school (15 miles one way).

The impatience of youth!
I simply gave up caring about the economy. I have bigger fish to fry, like completing my A-levels, and dealing with a grandmother that is constantly on the verge of death.
I may go back to worrying about how terrible the consumption is when I've finished my A-levels, and when my grandmother has finally given in.
