Temp gauge moving upwars

[ErdeM3]

I'm not 100% convinced, the system on E46 is self-bleeding, so I somehow doubt that air was causing the temp spike.

You may be right! All the main components is due for replacement…i am about to put this car into storage in the next 3 days, will see how it goes..

I will bullet proof everything upon return.
Appreciate the input.
