As coming into winter noticed even more my fl 1 td4 is taking about 45 mins to get the temp gauge to half way and obviously hot air taking same time to come through looking at people thoughts could it be thermostate taking needing replacement as maybe stuck open or taking longer to open ? Can say when it's hot stays hot ;)
 
Had same problem on mine and changing the termostat solved it. Replacing it is hard because there is very little clearance. There are two ways: the Haynes method which involves removing the cam cover, aux belt, water pump etc, and Creeeg's method which is how I changed mine.

or put one in the top hose, preferably in a proper ali housing like I did, works great. and cheaper (much) also looks the dogs .
 
If temperature will be on level when "half" way of gauge is reached (not go down when driving) thermostat will be fine i think
Td4 freelancers should have two types of aux heaters - one is FBH (fuel burning heater) second is PTC - an electric heater in your fan/air box inside cockpit.
For 90% you got one from these two systems, so check that it works. FBH can be tracked if small exhaust pipe is visible from LH side of front bumper. PTC if you got a relay on bulkhead (just aside fusebox). You also should have small fusebox fitted to L-box with ECM.
When PTC works heated air is available quite fast
 
I did mine the "hard" way
the main stat on these engines is well known for failing (happens on BMW's too)
I used a basic OBD code reader / data logger to check the water temp and found out that the stat was goosed.
As stated above - its tricky but do-able

Mine does have the fbh mate but not working for some reason and still should not take 45 mins for gauge to get half way even when that ain't working lol this is why stat is a suspect lol
