If youre battery is good and charged then it will be a bad starter

Why are you convicting the idle control valve? was it properly diagnosed? Could be coolant sensor, intake sensor,O2 sensors etc. Check it out first.

there is something wrong with cylinder power, and engine control unit have problem with smoothness regulation at idle, it might be spark plug, cylinder compression, cables , ignition coil... etc you should have some other fault codes witch are connected to this code, send all your codes pls

Hi sounds like the same problem I had crankshaft sensor my battery light came on and the engine would cut out sometimes would start straight away other times took 5mins to start again. But would get a garage to check fault codes costs about 40pound but could save you 100's as it may be a faulty alternator/battery.

What's your question? And what is the model and year of your BMW

did you reconnect the coolant level sensor that goes underneath the expansion tank ? it is fragile so possibly it broken - cheap to replace.

it could be something as simple as a broken exhaust hanger, take a look underneath, move the muffler and see if you hear it. I could also be a heat shield that has come loose.

Has to b the battery,if you changed the alternator then the batter isnt supplying any power to your sensors and computer. if your battery is weak the car might run at idle, but as soon as your drive your useing more draw. swap out a battery from a friend and you should b good.
