After several leaks I had the condenser replaced on 2007 Jazz by a well established air on firm. It still leaked so they came and re-gassed, then returned a few weeks later to test for signs of leaks. None found. They re-gassed last year but I just tried the AC and there is no cold so:
Where else could this be leaking?
If from compressor, then what sort of cost is this please?
Is it more cost efficient to have an annual top up?
Any other advice welcomed as I have spent a lot to get nowhere!
TIA
