Hi guys. I have owned my 3.0 2003 z4 now for about 2 months and have been very paranoid about everything from the beginning. The engine uses oil but have read that this is a known thing so I haven't really thought anything of it since. About a month after purchasing I had a mayo oil filler cap but not on the dip stick. I took this to a local specialist as I was loosing coolant also. After the specialist had it for a day he said there was nothing wrong, coolant had dropped because it had been over filled and mayo was there because I was doing little mileage (6 miles a day). He had pressure tested the cylinders and leak tested the coolant system and found nothing wrong. Tonight how ever the low coolant light lit up for about 1 minute then went out, this was after driving approx. 15 miles. So I stopped and opened the bonnet. I could see fluid on the under tray, had a look about and couldn't see any leaks or water marks around obvious areas of the engine. I had a look at the radiator and could see it was wet all over the front. I then felt the radiator hose and this was rock solid. Let it cool down a touch and checked the coolant level, there was enough there to get moving again. I managed to get home with a watchful eye on the coolant temp with my trusty mobile code reader/live data tool and the temp at its highest was 103°c. I kept the engine running and had another look under the bonnet the fan was spinning at a slow constant pace yet my A/C was not on. Am I being severely paranoid about it being HGF or have I got reason to worry?
Many Thanks
