BMW X3
i have a X3, 5 years old with 70000 miles. a few weeks ago the water temp light came on, when i removed the expansion tank filler cap the water looked more like grease. The garage replaced the whole coolant system including the radiator due to the contamanation. A week after getting the car back the temp light came on again only this time the car overheated, the car is now back in the garage only now they say the cylinder haed is cracked.
Has anyone experience anything similar?
