My X3 hasn't been able to start for two days now in pretty frigid weather (-35c). At first I thought it was the battery so I left the charger on over night and it still wouldn't start. I then went and bought another battery put it in and have the same problem.
When I try to start the car it is very slow to turn over, it makes a sputtering sound and almost starts but then dies. I popped the hood and noticed that fresh oil is leaking from the part in the picture, I'm wondering if that is the problem?
