Sometimes a the conditioner additive is enough to re-seal the unit, they get hard with age and leak. But ya never know. AC service kits are readily available in the US ,, don't know about Brazil. FYI - My 318ti is the touchiest on charge level I ever played with, it only needs to go down a few pounds pressure to quit working, and only 5 or 10 high and it will stall from overpressure.
