car is 2010 n52. I haven't checked in a long time, probably about a year now or so (maybe I checked 6 months ago and it still was in the normal range). cant smell anything and when I changed the oil about a month ago, it looked normal and no signs of water. no smells and like i mentioned, can't see any wet marks or white dried up areas...
Ill keep an eye on this closely now for next couple months.
