Hey everyone! So after like 10 seconds I start my 7, the "Add Coolant" light and buzzer comes on, then turns off after I drove a few feet. It only comes on when the car is cold, but turns off after I start to drive? On warm/hot starts, it doesn't come on. It runs perfectly fine and doesn't overheat. I'm just trying to figure out what the problem can be. Is there air in my cooling system? Or can it be the sensor directly on top of the radiator?

Thank you all in advance!

Pressure test the coolant system, followed by: bleeding the coolant system for 15 minutes, making sure the front of the car is higher than the rear. After that, I would look into that sensor.
