Hello - I drive a 2011 Z4 s35i w/17K miles. I do my own maintenance on my cars however, this is my first BMW, so - I want to make sure that I understand how the car needs to be properly cared for.

My questions:

1). Besides the obvious visually cracking, loose, squeaky belt issue(s) - when is a good time a belt and belt tensioner should be replaced for an 8yr old car not driven too often?

2). Is it necessary or recommended to replace BOTH the tensioner and belt at the same time?

(Fyi, this car has the original belt and parts but I would feel better if I kept it up with current parts.)

I would appreciate any mechanical advice you all can offer! Thanks in advance for any feedback/answers.
