I just bought a '97 bmw 740il with 90000 miles and I went to a local garage and had oil changed ( 5w-30 bmw synthetic oil) also air filter, everything was allright the car was running smooth but suddently the heating stop working, so i went again to the shop put the computer on it and read three faults: aux water pump, coolant temp. sensor and oil level/temp sensor.Afrer that I went home and coolant level light came on and service engine soon also. I go back to the shop and had aux water pump , expantion coolant tank and water pump replaced but the mechanic told me that oil from engine is leaking and he don't know where is comming from -yet, I wonder what that could be , thanks for any helpful info.
