German cars are weird. Changing a battery can disable many things. It will have to be reset by computer. Don't be surprised if you have to go to the stealer dealer for that.

fan electronics start at the sensor in the cooling system, and sends a signal to the ECM which in turn closes a relay and turns on the fan/s
There are 2 fuses in the system. one for the power to the sensor and one for the power through the relay
I suggest an accredited auto electrician with experience on your vehicle to quickly find the problem point.

The EGR valve opens when the engine is warming up, which allows exhaust to enter the intake manifold. This is essentially "extra air" coming into the engine. The engine has an "idle speed control" function, which is either a solenoid or small stepper motor connected to a valve that allows a controlled amount of air to "sneak" by the throttle plate in the throttle body. Fundamentally, it is the amount of air entering a fuel injected engine that controls engine RPM. A defective idle speed control ("ISC) motor or solenoid can cause the problem you stated. (I do not know which type is used in your BMW.) Often, a check engine light will illuminate of the engine computer cannot adequately regualte engine idle speed.

One of 2 things. The part on the end of the starter called a bendix is bad (most likely and less expensive) or the ring gear that the bendix engages is bad. (less likely MORE expensive). If you are comfortable with the work try locating a starter locally and replace it yourself.

If you just got gas, check your gas cap is closed tightly. If it isn't it can't pressurize correctly.

Remove all spark plugs and see that they all look the same as each other in the electrode area if one looks darker than the others or oily
then you have a faulty plug or ignition unit. In the case of an oily plug it's going to be a bit more serious
