The original water pump in my 2008 135i made it to 110k!!! I was shocked. But the inside cylinder plastic started cracking..
I changed mine as preventative maintenance doing other work under there. So glad I did.
But mine made weird buzzing noise.
And your water pump will run when car is off sometimes, it's programmed that way if it's too hot when you shut the engine off.
