Automatic air recirculation

[cool5077]

Hello. I have renault arkana with easy link.
I have a climate control and I have a trouble with them. When the tempreature outside +27c , climate control automaticautomatically turn on air recirculation. I heat how valve open recirculation inside and see this at ddt4all. Can you help me. how can I turn off automatic air recirculation?

And what do you want to do HVAC at +27C outside and inside you ask for +15C????
It is logical that internal car air is more easy to cool, instead to cool the oven air from outside.

[cool5077]

I understand this, but if I will drive for example 5 hours at a temperature of +27 and above, air recirculation will always be on. I think this is not correct, because there will not be enough fresh air in the car.

here is setting for my car - but my car has the rlink1 and not the easylink , so sorry not much help

[cool5077]

I don't have air quality sensor, but maybe if I turn on this function, it will still open air recirculation. Tomorrow will test this.

@cool5077 the car is not made to asphyxiate you inside, be sure about that. It knows how to adjust itself fast temperature inside car.
I have been In Saudi Arabia at +50C outside and to be possible drive a car which stay on sun all day, we need to start car put AC at maximum and stay out of car waiting at least 15min for cool the interior.
To be against the system is not always the best.

if your arkana easylink system is A-IVI v1.9 you could try adjusting this setting (I presume you have got past the arkana security gateway on the obd2 port?)

And I dont know what HVAC ECU you have in your arkana - but for example look for the AQS setting or air quality setting.

Changing these settings may possibly stop your car from auto recycling the recirculation flap on the heater and allow you to bring in fresh air from outside?

well, if anything its 'off / disabled' you want to set it to.
What the AQS does is monitor the air from the outside. If it deems that the outside air is polluted then (along with the setting in the rlink or easylink) it will automatically trigger the recirculation flap in the heater and close it so no more outside air can enter the inside of car

So, the weather was cold, I can’t test enabled air quality function. Now the weather warm and I can test. Result test- air recirculation turned on automatically 😞
I don't know what to do, any ideas?

see on my car with rlink1 it has a auto recycling setting in ddt4all.
You could try your navigation for your easylink and go through all the settings and see if there is something similar.

iam presuming seeing as you have a later renault and with a easylink you will have to get a token to unlock the security gateway to make any changes.

How can I get token?

[AndyIreland]

I think only renault garages and authorised repairers / people with garages can order a token:

possible maybe if you took apart the dash and found the right points you could possibly bypass the gateway by directly wiring it up .
here is details on the Clio5 gateway - I suppose yours would be nearly the same?

So, I check autorecycling on my easy link in ddt4all, I can’t configure this. I make PRESENT, but it tells me - command not recognized

[AndyIreland]

have you unlocked the security gateway?

[cool5077]

have you unlocked the security gateway?

as far as I understand, it was unlocked. But I can’t write the data, because it unsupport.
I have a climbox, but I tried to write in MFD.

[AndyIreland]

OK if you are absolutely sure the gateway is unlocked , then other things I can suggest is did you do a search with the DDT4all magnifying glass or did you pick the ECU's manually? (if you pick wrong ECU then you could come up with unsupported)
If you are changing the parameters on the right ECU (no red 'NO DATA') on the read column, then try increasing the CAN timeout to 600ms
see how you get on with that .
Other than that your ELM327 may not be totally compatible with DDT4ALL (has your ELM327 adaptor got the required PIC chip in it that DDT4ALL wants?)
