Is my air con clever or is something wrong with it?

Hi,

Can anyone with a mk2 Leon (ideally a 1.2 tsi) Do a little test for me please?

Basically, my AC on my 2010 tsi is ice cold if you put it on lo on the climate panel and the rad fans spin at low speed.

However if I set it to auto and pick a temp ie 20 degrees the fans stop and only come on for a few seconds at a time when the car is stationary. This results in noticeable air temp changes in the cabin when stood still. Is this normal?

I worry as I previously had a mk2 toledo with climatronic and that had the common resistor failure for the low fan speed which made the fans pulse at full pelt to keep the AC working properly (until they also failed) and I fitted a nime box to get low speed fans back.

So could someone test on their drive when they pull up after a journey please. When i stop and pop the bonnet the fans are not running. As the fatter AC pipe to the left of the engine gets warmer the fans then spool up on low and the pipe gets cold again, then the fans stop again. It will then keep doing this. (Unless I spin the dial to low and then the fans spring into life and stay on.)

I wondered if it was either a problem or some kind of eco thing?

Thanks guys!

Not sure exactly what yours is doing but obviously with climate it's not "hot" or "cold" necessarily. It monitors the temp in the cabin and will adjust temp/fans accordingly to try and keep the temperature at whatever you set it to.

Obviously if you pick LO it will just go all guns super cold and HI will be make it as much like a sauna as possible.

That's my understanding and I think how mine works, the missus hates it because it's not classic hot or cold or somewhere in between... so sometimes you do get extremes in temp similar to what you describe I think?

That's just how climate works (or doesn't depending on how you look at it) I think.

Hi. Thanks for the reply. It's not the interior fans I'm on about, it's the fans in the engine bay that cool the AC radiator. I know what you mean about climate though my wife doesn't like it either!

Oh haha sorry! Well I've only really ever heard my fans kick in when it first turns on but mines a 1.6 TDI
