As I knew, my 2008 E92 was low on AC gaz (only 0.37 lbs was in the system). But it was working I got coolest temperature reading still around 44 deg F. (7 celcius) on best setting. but not in large amount in volume of air...

My local AC specialist drain everything and put back a little bit more than the recommended 21 oz (1.3 lbs) + the correct amount of oil. The compressor is now silent again !!! Oufff...! PRessuse is good too. But he didn't get as low as initially... He re-drain everything and put back a little less than the 21 oz.

Still he didn't get as low as initially... He charged me 170$ and let me go... Everything seem perfect to his eyes...

At home, I did not get cooler than 50 deg F. (10 celcius)... Not good to me.

Please, I need help...
WTF ?????

PS But the spec is 1.3 lbs plus or minus 0.02 lbs, which appear thigh to me...

I guess just make sure that the correct amount of PAG oil is in there plus gas. If it's under or over, it's not going to operate normally to protect the compressor. Fill it to exact spec. Everytime I overfilled my compressor, my compressor would surge on and off and it wouldn't cool as well. As soon as I evacuated some, it worked perfect.

The end : the drain of my evap was clogged making the heat transfert innefficient after some minutes ... 2 visits at the garage and 400$ bucks later, the air is blowing at 4,6 deg cel (39 deg F) :-)

With air gun and camera, they open the drain. I have a risk that it will come back... Was it the best way to go at the evap and clean it effectively ? From the insine or the outside ???

Thanks

Coil drain tube (from the drain pan).
The pan seems over the transmission and the final exit tube is 8 to 10 inch up the bottom of the car... Black rubber...
I need a pic to show you...
