ok at my Z club meeting yesterday I had teh only Z31 (figures....). anyway, they were all admiring the car when they wanted to see the engine, than asked what the sound was. it was a mechanical sound, coming from the front passenger side, like up by the headlight. it made the sound when I put the key in but before I started the car. anyone know what that is? some kind of motor or pump or something? I hear it all the time before I start the car up and never really paid attention to it but come to think of it Id like to know what it is.

 

thank you AGAIN. and I guess its a normal sound.
