There is no belt tension "adjustment" on BMW E36 engines. There are
automatic belt tensioners for both the Alternator-Waterpump-Power

How do these automatic belt tensioners know how much tension to apply?
Is there a spring? If so, isn't it possible for it to fatigue?

Thanks in advance.

Yes, spring tension. There are two types. One that has a little
mini-shock absorber looking spring assembly and one that has a torsion
type spring assembly. You'd have to look up your car to see whaich you
have. And yes, either way it is possible for them to go bad.

Dunno about BMW. FWIW, on the Alfa 2000 GTV I had back in the 70s, there
was an oil pressure operated chain tensioner. I think there was also some
kind of ratchet arrangement to keep the tension, once it had been adjusted.

We were talking about the drive belt tensioners, not the timing

belts/chain tensioners.
