When using OBD Bluetooth adapter i get readings my operating temperture during drive going to 105 Celsius and stays there. is this the normal temp? i think its quite high.

what are your experiences?

 

my 535i runs about 98 Celsius or so

 

That sounds about right. on the highway, my 550i runs at 102 F. If it senses you're driving aggressively, or putting the engine under load, like going up a hill, it'll drop the temperature about 10 C. You have an electric water pump so the differences are more pronounced when the engine switches modes.
