Z3 power steering resevoir location

Hi all. My bmw z3 1999 steering wheel is bit stiff and I was wondering if the fluid level is low. But I have looked everywhere many times but cant find the resevoir cap. Can anyone tell me the location please.

Hi there, if you look in front of the engine down below the the airbox near the alternator you should see the PS reservoir. Please note that the power steering system in BMWs uses dexron automatic transmission fluid.


Best of luck!
