Clio 172
So, being here around 41°C in these days,
my 172 air con is not helping that much keeping me from sweating.
Thought it need to be regased or topped up.
No, was about perfect.
In the traffic seemed just fine, not as cool as Artic Pole, but fine.
But as I hit the MW, temp coming out of the vents went up, no matter what temp I set in the automatic climate control, recirc didn't help nor rising the speed of the fan, air was warm, not cold.
Compressor is kicking in, you can hear hit clearly at idle, if you hit the button.
Until you stand still, everything is about fine, as you move, you start to sweat, a lot.
So I made this test:
fitted a temp sensor in the central vent
at idle you can hear and feel the compressor kicking in
and the temp lovers until 9 or 10 degrees in a few seconds
if you slowly rev the engine (neutral, standing still) until 3500 rpm or so, everything is ok, temp stays around 9, 10, 11 or so,
if you go over 4000 the temp starts getting higher and higher
you lift off the throttle and leave it at idle
in a few seconds, you hear the compressor kicking in AGAIN
tested this many times, confirmed all the times
at about 4000 rpm the compressor is clearly disengaged
you cannot hear it disengaging,
'cause the engine sound obviously covers it
but you can clearly hear it engaging again at idle
I thought this was due to the Renault Sport Ecu,
in fact, partially it is,
switching quickly back to stock ecu,
it behaves the same, except that the limit is not 4000 rpm but around 6000 (had not so much time to find it exaclty)
has anyone ever find out this?
