Overheating Mystery

You are better off looking at the live engine data for accurate temperature. This will give you a better idea of true engine temp. The fans are under ECU control. So if they aren't coming on, the engine isn't as hot as the gauge shows. Or the engine is hotter than the ECU thinks.

Your mechanic did modify the original thermostat at the back of the engine, didn't he?

BTW it is under zero celcius out here, so even tho going uphill, the requirement of cooling fans seems absurd to me.

If the fans kick in late, what would be your suggestion to fix it? Replacing ECU is the only way?

Yep, he emptied the center of it and put it just as a placeholder to prevent leakage.

The engine gets it's temperature information from a sensor. It is possible for the sensor to go wrong.
What year is your Freelander?

99, temp sensor at the radiator side of the motor is renewed. I dont know the place of the other one(s) and they are not replaced.

A 99 Freelander has 2 temperature sensors. One is for the engine ECU. The other is for the gauge. So it's possible that the gauge sensor is not giving the correct signal to the gauge.
