To All Sifus, I have one technical question. Is it normal for my 2000 E46 coolant level to drop every 3-4 days? This has never happened before but lately I need to check the coolant level frequently. There is no leackage whatsoever underneath the car. But it has come to my attention that the coolant stick drops to minimum level every 3 or 4 days. Would really appreciate on any advise given. Many thanks in advance.. Andy
