[LUX3]

Hi Aziego
I read your thread; frustrating indeed.
Pretty sure I don't have any leaks because my previous E92 was loosing a small amount of coolant and, whilst it never dripped on the floor, there was always the sweet smell of hot coolant in the engine bay. Eventually pressure test detected hole in radiator where crusty deposits of dried coolant had accumulated. So that was easy fix with new radiator, problem solved in that case.
This car is using a lot more coolant, but no dripping on the floor and no sweet smelling odor of coolant. ... So I'm baffled!
If it's going through the engine, it might show up in emulsion of the oil when I change in a few months, (although oil filler cap is clear). No whispy smoke or odor from the exhaust, but then the quantity being consumed is probably too little to detect in this manner.

Are there many others with this problem?
I have read that B58 owners suffer as well. Similar design engine??
