E4 air conditioner

Hi, someone know something about error E4 on climatronic of Land rover Freelander TD4 2004? Thanks in advance Matteo from Florence Italy

So

You have an automatic air conditionning, and have E4 instead of the temperature display ?

The problem, automatic air conditionning comes as an option, there is almost no documentation.

What are the issue, no heating, air flow to the maximum ?

No cold air comes out, but the engine run.

Hi,

Since when do you have the car ?

Does it heat, when the engine is at temperature ?
Can you control the air flow level ?
Can you see the internal / external temperature ?

Oo an FL1 with electronic climate control, that's rare.
It was a seriously expensive option on the later facelift cars only, but it was so expensive that almost nobody optioned it.
As Andy said above, it's virtually undocumented in an service or maintenance manual.
However it's still just AC, but with servo controls of the blend doors, so start with simple stuff like making sure the refrigerant is at the correct pressure.

The pressure it's ok, i'm sure about this.... I just recharge the gas.

Hi,

Have read the code with a fault reader ? With an OBD reader ?

Do hear the Compressor Clutch engaging when you put the air conditionning on ? Simply push manytimes the « auto » button.
Manual / auto -> AC On.
Eco -> AC Off.

Is the radiator fan in front of car running, when you put AC On ?
