You might have a door lock actuator (electrical) problem. I would let your local BMW dealer take a look at it. Good luck.

Check the body control module for proper operation. Check with the dealer on the exact procedure. It may have to be replaced.

Friend, you've changed everything but the right thing. The temperature sending unit. It tells the computer to go into cold start mode to start the engine by putting more fuel into the engine. If this sensor is erratic, sometimes don't work, it will cause a hard start situation if not in cold start mode. Dealer cant find this because it's a manual thing and may not be showing up on his tester.

probably a bad air/flow sensor, try to clean it with sensor cleaner, its by the air intake filter box. if not clean the throttle body really good. pls vote.

run the fault codes first as the light also reports on transmission problems just turning a light off doesn't fix the fault that put it on in the first place

have a compression test done to check for head gasket or cracked head

Year, make and model of your vehicle would help. Do you have any codes in your ABS control module ?

The pressure sw. on the dryer maybe weak but the way you explain it I think the sys is low on Freon. The reason for this is you said it did not get that cold. I would add a half can or one to the sys and see if the compressor cycles longer. Hope this helps.
