That is what i mean...

You have not. If the cooling power will go lower and lower, you have to change a part named "Trockner-Flasche" (dryup-bulb?) and refill gas. If you have the old gas you have to install an upgrade kit (about 200EUR ) for the new "earth friendly" gas.

THANK you for this invaluable answer ! (English humor)
But the real question is to know if i have to reload every year air conditionning system with gas or if i have to look for leak?

Best regards

I think if the Air Condition will not work it should be changed then ...

Please, somebody can inform me on the frequency of gas cartridge renewal on E31 ?
