I always have mine on, and In a way yes it is reverse cycle, it adjusts to the outside temps, so if it 15c outside and you have it at 22c inside, warm air will come in, if it's 30c outside and you have it set at 22c, cool air will come in.

The system is not rocket science, set it to where it's comfortable for you and leave it, there's no affect from whatever the passenger side is set too that I've noticed.

Once it gets to temperature it then begins to regulate/cycle.

With the rear zone, when the front is set to auto it works with the front settings..

The problem with that though, is what people want, is for the vehicle to go to a higher or lower temperature for some time, and then correct back to normal comfort.

In winter, the normal setting might be 22 or 23. In summer, it may be 21 (due to sunshine radiating heat there are differences). But when you step into the car in the winter, the whole car is cold. Its radiating cold too. You probably want to the temp to go up to 25, and a female 26 or 27, and then have that high temperature sit there for 10 minutes. Then you get warm, and car gets warm too (the radiating surfaces) and that's when the little lady dials the temp back down.

Its the same in hot weather - set it at cold, until you get that way. Then dial in your comfortable temperature.

These days, we have to rely on computers.

Another annoying thing is that I always check that the left central dash air outlet, will aim towards my face. So that I can set the left side for cooler, and blow the air from the left central onto my face. But ... with temperature controls being only - what was it? - 5 degrees different, even that trick is getting less useful.

Why can't they allow me to have a top and bottom temperature. I'd love that and I reckon its safer too.

By the way, I reckon the D4 takes a long time for the heater to get hot ... is that normal?

By product of being a Diesel - can take quite a while depending on outside temp... By a while I mean about 2-3 minutes... Especially noticeable if you pull almost immediately into stop/start traffic.

Agree with you on the warm feet, cool face... I've always considered that a safer option - And can achieve it on cold days - Feet and Screen works well - the screen cools the air as it passes over.

My 20yr old camry does this well - the blanking plates behind the dash vents dont work so you can set feet to hot, turn the aircon on and get warm feet and an icy face.

Im happy to swap for a D4 if anyone wants :p

Cheers,

I don't think it's because it's a diesel, but more the interior size of the vehicle, I've had quite a few cars over the years, and I reckon diesels have always been quicker at heating up than the petrol vehicles of a similar size.

(eg) our Ford Explorer, Falcon station wagon

The D4 is the quickest of all, mainly due to it having rear air, it also cools quicker too, great for when we have the fridge in the car.

Baz, I think he's referring to the point in time in which the vehicle has got sufficiently warm coolant to start pumping warm air...

I've noticed in Winter the engine barely runs warm by the time I'm at work ;)
Starts to just produce reasonable heat by about 2km from home... (no stops in my journey).

Once its going - it works amazing...

Are you talking the metaphorical "walk into a room and stand by the fireplace"? :)

LR produce a perfect option for winter for this - Heated Seats :cool:

Seems I have a well informed female ;) She just sets her side in the D4 at 23 and leaves it there... And I just leave it there... My side - 21... And doesn't move... Rear set on Auto to match the front...

In the 90... We have CC pack.

My D4 as soon as the car starts even on cold mornings even with it on auto will start blowing air and even if the air is freezing cold, where as the bosses Audi won't blow anything until it starts to warm up and then starts blowing warm air, i like the Audi idea there because jeeze its cold some mornings. But i must say the D4 has one of the best air con systems around even hot summers day it cools very very quickly and does a great job.

Strange, mine starts blowing warm air less than a 1k from home, I work 43k from home, I'm warm for 42ks:p

How many stop starts from home do you have?

I have none.. and I'm at work in 3km :cool:
