I ended up buying this part along with the second one from him for $60 extra to put onto my 06 650i which was running at the time . After giving them to my mechanic (which has been certified dealing with foreign cars for many years ) installed them, the car has yet to start again. Now nearly a month later I even got the car towed to another shop (since it won’t start anymore) & now I’ve been told that the engine has lost compression & I’m going to end up needing another engine.. not necessarily putting the blame on him but before I installed the parts that he said have been tested and work, the car was still running now unfortunately I’m not sure what to do . Thanks man ...
