Did you recently add Freon in your AC system? You might have too much Freon in the system, which caused the AC compressor to recycle more frequent than normal. Or you might not have enough Freon in the system. These BMW's are very AC system are very finicky. Get an AC gauge and check the level (high side & Low side) pressure.

My 318ti coolant fan is not working. just changed the radiato and bled the system. the fan only comes on when the ac is on.

fan will not come on until pre determined temp has been reached
will come on with a/c that is normal to lower condensor freon pressure
you do not state a overheating problem is the temp gauge going way up
or stays normal

verify the engine cooling fan runs at idle without the AC on, it should come on around just past 1/2 scale on the temp guage, do not let it overheat! these engines have aluminum cylinder heads and u can blow the head gasket out, let me know the results
