he means that did your mechanic vacuum the ac lines?
the drier bottle is always supposed to be bought brand new, otherwise it is just a show piece, it won't be doing any drying action.
i hope your problem goes away with a gas refill, i always wanted to see someone fit a baleno condenser in a margalla.
btw don't get a new dryer bottle if you want to go back to the same mechanic, he will most probably waste it
