I’ll do more research on the motor and bmw but if this is normal, should be purchasing coolant to refill every service ?
My last post on this thread.

1) I posted before here, the SA is correct. Cold weather causes the coolant level in the system to contract and can trigger the low coolant light. Whether you choose to believe that or not is up to you.

2) The coolant may or may not have evaporated...no one knows (including you) that the level was correct when it left the factory

Up to you if you wish to keep some additional coolant around for top ups. It should not require it other than at the start of winter, as mentioned previously. You are under warranty...if the dealer is not far, you can simply drop by if the low coolant warning were to pop up and they will add the 6 or so ounces and you are on your way.

PS, thanks for posting your service video...cool to see the M Sport differential (limited slip) used from 2020 on has a coolant fins on it. Alas, my 2018 has an open differential (non locking) and no fins.
