Hi everyone. For once this isn't a topic about a problem with a Freelander 2! I know there are some very knowledgeable people that are very clued up about the cars we drive on this forum. I quite like knowing the inner workings/the geeky bits of Freelander 2's and hope you don't mind me picking your brains.

Thanks for the post BossBob. Here's where I'm at so far with trying to figure out how the Freelander 2 warms up the diesel when it's cold.

My Diesel filter doesn't have any sensors connected to it, I don't think many in the UK do.

You can see at about 2:50 in this video ( https://youtu.be/fuAY1_hFuPQ?si=zB25-hIfW2ubfdBK) that we disconnected the fuel temperature sensor from the filter.

The fuel filter bypass valve is entirely mechanical and recirculates 95% of fuel when returning fuel is below 10C.

What Jules says. The thermal system in the fuel filter is self contained. That is why it is so important to use an authentic filter. |

Ah, I was thinking about the bottom of the filter, there are some FL2s that have an electrical component that connects into the bottom of the filter. Hung like Einstein, smart as a horse. |

Its for a water sensor though not fitted on most FL2s 2013 FL2 XS.

That puzzled me for a while as my 2014 even has the wire and connector for that in its loom - but the filter have no sensor just a dummy connection - a rollover from the Evoque loom at the end of the FL's run. Jules |

As above Back last winter we had a few weeks (don't laugh MRRover75) of -12 +/- degC and the Freelander started with no problem at all. Double glow plug and keeping the battery in tip top condition is critical. When it is due to get cold like this I tend to stick the battery conditioner (CTEK) on overnight to keep things warm and charged. Never fails to start in the morning. |

Just to round up this thread and in case anyone else is interested in how the Freelander 2 warms up the diesel on cold days in a very basic form. I first started off by opening up an old diesel filter we had to see what was inside and how it worked:
