If the ambient was 0C I'd need to be running 20 mins+ or do about 10 miles before the gauge reached normal.
Sounds very much like mine doesn't behave as it should. It's due an annual service very soon so I will talk to them about it. If there is an issue I will expect it fixing for free seeing as I flagged it a year ago and they couldn't diagnose it.

Might it also be a fault with the temp sender, wiring, or with the cluster, and that the engine is reaching normal temperature quite normally? 58 HSE, auto, lago grey, tints. Mine and my dogs Storm and Sky

The main reason why it's a problem is that the cabin heater is next to useless for the first 10+ miles and beyond that, it is only acceptable once the T gauge is at normal. Because of that, I think the engine isn't heating nearly as quickly as it should.

Doesn't sound right Andy, even today with the low temps we have within 3 or 4 mins were getting warmish air.

I assume you had the pdc heater reconnected during the recall? It needs testing to see if its working At work

Sounds like the thermostat is faulty - Mine is as warm as toast after several mins. driving  2007 Freelander 2 HSE TD4 Manual with Premium Pack & Moonroof.

During recent days (-7°C to -13°C) cold morning starts the car takes anything from a 2 second delay to a 5 second delay to fire up. At -13°C it was a distinctly lumpy start.

Once underway with the CC set on auto and dialed cabin temps set at +22°C the car takes between 10(-7°C) and 15mins (-13°C) to reach warm air blowing in the cabin and engine temp guage to read normal.

The heated seats respond immediately and are really toasty after 3mins.

Have you tried pressing the "PROG" button on the dash. It turns on the PTC heater and warms up quite quickly. ______________________

its 0 here and my wifes car has not been run. In the interests of science I'm going to see how long / how many miles it takes to hit the "normal area ie the first mark on the white sector. I'll try not to stop but I cant go faster than 20 - 30 mph due to the snow - I'll report back very soon.

"pdc heater"

What and where is a PDC heater?

"Have you tried pressing the "PROG" button on the dash. It turns on the PTC heater and warms up quite quickly."

I thought this was just for the climate control and front and rear heated screens? PTC heater what heater???

give me information NOW

Back already!

Took 3 mins / 1.5 miles for the car to feel "warm and comfortable" and reach the bottom of the indicated white normal zone and at 4 mins it was scortching and well into in its "normal zone". At 3.7 miles it was nearly at "half" but was very comfortable!

External temp had gone to 2 deg.

3.7 miles in total took 7 mins.

I did not use the prog button or heated front or rear screens, I used the wipers and set climate to auto and temp to full on both sides.

I reset the trip counter so if you look at the trip counter in the pics versus temp it should give you a fair idea.

PTC Heaters........

Positive temperature co-efficient - PTC heating elements are small ceramic stones with self temperature limiting characteristics. PTC stones have fast heating response times and plateau once the pre-defined reference temperature is reached. The shape of these stones can be be designed to be square, rectangular, round, ring or doughnut style. Above the reference temperature, the semiconducting and ferro-electrical properties of the ceramic are utilized to produce a rise in resistance of several orders of magnitude, and hence produce it's self limiting properties.

This resistance rise can be experienced over a temperature range of a few degrees Celsius. This PTC attribute results in a heating element that self-regulates at a pre-set temperature and automatically varies its wattage in order to maintain that pre-set temperature. Hence, a greater degree of thermal dissipation (cooling) will result in higher power.

The materials used are doped polycrystalline ceramics based on barium titanate. Once the ceramic body has been formed through processes including blending, milling, drying and sintering, metallized contacts are applied to the surface to facilitate electrical connection.

Yes thanks perfectly clear....as mud

we have already discussed this Dave, the PDC comes on automatically when its cold, no need to press 'prog' now do pay attention  At work
