Dumb question but I need some advice
So my wife's 2018 X4 M40i has a bad coolant temp sensor. From everything I have seen online it says that I am supposed to get the air out of the coolant system after replacing the sensor because the air may damage the system? I've never heard of this sort of thing before but I wanted to get some advice on it. The coolant reservoir doesn't appear to have a "bleed screw" so if I am supposed to bleed the system of air where/how would I do this? Also for context, from my research this is apparently the N55 engine. Thanks in advance!

Yep, as far as I can tell it only has one and it doesn't have a bleed screw or anything. The temp sensor is not that hard to get to. I'll take a pic and post it. She is in healthcare so she won't be home until later. I thought it was the N55

Coolant Temp sensor replaced-still no temp reading
I replaced the coolant temp sensor but the check engine light is still on and the temp gauge on the display isn't working. Any thoughts?
