Any idea how it is the easiest to find aircon AC leak on a C-class w205 ? It keeps gas only few months and need refill.
I read about dye or sniffers ?

And do you know if it is bad to use aircon without enough refrigerant gas in the system ? Should I refill as soon as it's not cold anymore ? (until I fix it definitively)
