Every now and then it does not want to crank at all... This is especially true when the engine is hot. Or when it's cold early in the morning. I assume that's when high cranking amps are needed.
Once it cools down, I can get it started on 1st or 2nd try.
My car is an MY09, does not have iDrive, and I'm not seeing any errors on the dash display.
Is this the battery on its way out? Or is it the alternator?
Car has about 85,000 kms and I suspect this is the original battery!!
Thanks for your help.

Do you mean nothing happens at all when you press the starter button? Even a low battery will at least click the starter solenoid
Probably the starter motor, not an uncommon failure on these cars, usually the starter solenoid on it gets stuck and another attempt later and it fires up no problems. Does it crank strong when it does start?
