okay sorry bout that, ill drive the car for about 15min. doing around 50
mph, the temp will go up a little -just past the blue, but if i stop and sit with it running for about 2 min the car heats up to the center of the guage. is it bad for me to drive the car with it staying cold? is it normal for the thermostat to go out?

that doesn't sound like a problem at all. It is very normal for a BMW to heat up quickly. If the temp gauge hits middle and stays there, thats normal. Middle is where you want it. If it goes up further or lower, then you have to start thinking there is a problem.

no sorry im a retard , let me explain better- i can drive for 15 min and the temp guage only goes up a little (steady drive at about 55mph) it doesnt go to the center or normal position- now if i stop at a light and let it sit at idle the guage will creep back up to normal. Now- can i drive the car a couple days until i get it fixed if its the thermostat?

ohhhh...seems like it isn't a real big problem, so long as your car itself isn't actually overheating. It just seems like you don't accurately know how warm your engine is. You can go a little while driving like that, but I would definitely recommend fixing that soon enough.

Sounds like a stuck thermostat. They're nice a cheap to get a new one so go ahead and replace it.

I would not disreguard this as no problem. It seems the thermostat is stuck open.
These engines are designed to maintain a constant operating temperature in which the thermostat maintaines the temp.
You would not want the engine to have the drastic changes of heat expansion and contraction.
Once up to the operating temperature is achieved the engine and all the mechanical clearances are designed to stay in that range.Mess with that and it causes undo stress on components.

FIX it !!!

Don't disreguard my low post count I have been messing with vehicles, motorcycle and Aircraft for a long time.

I think all that they were saying is that he doesn't have to drop his car off today, he can wait until whenever this week he has time to fix it.

thermostat sounds stuck open, meaning the flow of coolant is at its highest at all times,
