Its not mileage that counts!!!!
Its TIME IN SERVICE!!!

The water pump impeller doesn't wear.. All it is moving is clean coolant, there is no friction. What breaks the impeller blades is EXPOSURE to the environment that the impeller is a part of whether the engine is running or not.

Because of this we see cars with 10K miles from 1997 crack heads because the impeller has become brittle and a piece of it snapped off.

The last M96 engine that was built came from 2005, at this point ALL M96 engines are AT LEAST 5 years old and ALL of them need the water pump changed.

Don't consider mileage for an AOS, water pump or IMS precautionary procedure to be carried out. The IMS bearing's outer seal is exposed to engine oil even when the engine isn't running, the seal breaking down and allowing engine oil to attack the bearing and wash away the permanent lubrication is what begins the IMS bearing failure.
