I bought a 2014 116i with non working air con. When the gas pressure is low, the compressor won't run.
I bought a regassing kit from ebay for £75 (inlcludes lubricant and leak stopper) and followed the instructions - easy to follow and this fixed it.
But, there must be a leak because the pressure slowly drops so the air con becomes less and less effective. It's still working after a month but less well and eventually the compressor will not activate.
Finding the leak won't be easy.
NO DON'T LET A BMW DEALER ANYWHERE NEAR IT.
Take it to an air con specialist if you don't want to regas it yourself.
I bought a BMW compatible fault code reader (a BM500 off Amazon) and this told me the compressor was disabled due to low gas pressure. No fault codes for the engine.
