Heater
Can anyone help please, I have a 2009 2.4tdci and the heater when then idle is blowing cold, what do you suggest to improve this ? It is perfect when the revs are 2000 +

Does the heater valve move when you turn the knob inside (heater valve seams to be a cheep part on these and breaks often) Searching for my first Defender...and started just as Covid hit, so talk about timing.

5 months after starting the search I found it, and here is the details

Yes, it works fine when driving along at 2000rpm but when stopped on idle the heat stops

This is fairly normal on a TDCi, and provided that the coolant level is well up there is not much you can do about it. The heater is extremely sensitive to coolant level, but will also vary enormously according to what the engine is doing.
