Been watching for my glow plug light for the last few starts, had:

No Glow Plug Light, instant start, Dash Temp Indicator 2 Degrees.

Yesterday:
Glow Plug Light, about 1 sec delayed start, Dash Temp Indicator 0 Degrees.

This morning:
No Glow Plug Light, instant start, Dash Temp Indicator -4 Degrees. Question

Thought it would come on for sure, this morning. Maybe it's significant that there wasn't as much frost on the car this morning at -4 as there was when it was 0 Degrees?

Crank delay takes its input from the engine cooling temperature sensor, not the ambient air temperature which may explain the anomaly.

Fair enough, but I wonder why the engine cooling temp sensor was warmer with the ambient at -4 than 0 ?

Mine came on yesterday for the first time -3 here although car still failed to start after 6 attempts, I had to put the battery on charge over night . This morning -3 again no glow plug light but the car started first time so i think I may need a new battery.

Although only owning the freelander 2 for a few weeks, I have never noticed the glow plug light.
This morning it was -4c and engine started fine with no light.
It seems the early FL2's are reporting similar.

Joe Fix it until it's broke !

Why the hell it have to be like this... why they cant design it to work like manualy from button etc, just like older cars, you just turn the key to glow so much as u want!

this could be one kind of project to somebody to figure out if it could be manualy done Smile??

same in here sometimes it shows glow light, but im doing this 2 step ignition, just setting up the powers whit out clutch on floor, 3-5 times just pressing it on and waiting until light goes of and then again again

Mine lit for the first time in memory this morning! -1 deg in Portsmouth, with thick ice. Nice to know it works (2007 XS).

No coil light yet though engine has a definite delay before turning over a bit laboriously. Makes me wonder about battery life and whether its getting close to needing a replacement. 2010 XS

It's not only to get the glow plug pre-heated, it also helps with cranking. The start relay is held in by Engine Man ECU until the engine starts. Normally, after a pre determined time, if the engine doesn't start, the Engine Man ECU open circuits the 0 volts at the start relay coil to stop cranking. This is to help you prevent flattening the battery.
The delay and glow plug w/l works fine on my car and I think it's a really good feature. Another member of the failed FL2 clutch/DMF club, twice.

That just shows the difference, I tried starting mine last night at about 2230 and it was -1 and no glow light or delay, just started right up. Same year as yours, same city as yours, same night and temp as yours. Freelander 57 plate XS Blue Auto

Ay EY correctly pointed out, it's nothing to do with the ambient temperature, it's coolant temperature.
Had the vehicle been used earlier in the day? Another member of the failed FL2 clutch/DMF club, twice.

United Kingdom 2007 Freelander 2 TD4 XS Manual Lago Grey

Sorry for the resurrection of an old thread.

I am having issues with my 07 xs. It doesn't like the cold. Anything under -3 and it cranks until the battery goes flat. There is no delay when I press the start button so I think it's missing the pre-heat phase. Once I've got it started (jump off my 02 200k miler FL1 which starts first time every time) it runs perfect, no smoke or roughness.

Is it new plugs I need or is there a sensor that tells it to preheat?

Thanks

I replaced the battery about 18 months ago. There appears to be plenty life in it, it will turn over for 5 - 10 minutes before going dead.
