Do you have airconditioning in use? This will affect fan operation.
The fan relay is working as it should, as it turns the fan off when you switch the ignition off.

So its normal to work almost all day

Hello @Dragos1990

Doesn’t sound normal if you’ve not got the Aircon running. Our local Evri delivery chap has a 72 plate and leaves it running whilst working and the fan isn’t constantly running

Amongst a myriad of issues, you could have ;
A faulty fan temp or coolant temp sensor.
A stuck thermostat ( should show as an over heat on the temp gauge).
Wiring fault or stuck relay.
An emerging problem with the coolant system such as a beginnings of a head gasket leak.
( could show as under heat or over heat no the temp gauge.
Is the ambient temp sensor reading correctly on the dash? - that can cause all manner of running issues…the list is endless

A check of any existing fault codes and live data is in order me thinks….

 

[Dragos1990]

No any faults
And we’re is the relay position
And no overheating
And sometimes start on stage 2 of the fan

Still under warranty?

Plus get exterior temperature sensor fixed

Can be a problem exterior temperature a problem?
And start stop don’t work

 

[AsdaPricey]

…the no reading of the ambient temp reading will be a cause of all manner of issues - have you had a new wing mirror in the past?

On vehicles without adblue no exterior temp signal = no dpf regeneration.

I do not know if lack of exterior temp signal affects adblue vehicles but it could.

 

[Dragos1990]

Yes I get a new wing mirror changed

My van got adblu

My van got adblu

No exterior temp signal could still cause expensive problems. It is up to you if you wish to avoid the risk and get a mirror with a temp sensor in it.

 

[AsdaPricey]

Did your symptom start after the mirror change?

 

[Dragos1990]

Did your symptom start after the mirror change?

I buy the van from auction and was side damaged and I change the wing mirror I’m not sure if got this problem before or after I change the mirror
But start/stop don’t work because the fan works almost of the day

 

[Dragos1990]

If I don’t drive after 5 minutes fan stop and get back after 10 minutes and on motorway same stops

 

[AsdaPricey]

My advice would be to reinstate the temp sensor function and work from there

 

[Dragos1990]

Al good now I take down the wing mirror and the temperature sensor don’t was connected and now everything works perfect and start/stop works perfectly now
Thanks for your help
