Alot of e39 will have the sound from belt tensioner. This is mean the tensioner need to change. As long as the belt is tight enough then you no need to to change the belt tensioner.If you able to unplug the belt tensioner then put libricant oil or 4WD oil. Or you can unplug water host in order for you to spray 4WD oil to the bet tensioner.Due to belt tensioner dosent have the bearing, whenever the hole holding the shaft of the belt tensioner is bigger causing the lose of the body. Then the friction between moving parts of the body causing sound. If you able to add lubricant oil to the belt tensioner the sound will reduce.I have changed the new belt tensioner recently. But still got very little sound from the belt tensioner although it is new. To prevent this happen, please add lubricant oil to belt tensioner before fit to your car.

bro which belt tensioner are you talking about?the main one or for the a/c compressor?
the a/c tensioner does emit sound even if it is new but not due to the tensioner itself but due to the asembly that hold the pulley.on this assembly are roller bearings that wears due to age.i've lubed these roller bearings but this only works for a while before the noise comes back.
and no it is not wise to lube new pulley bearings as the lubricant WILL attract dust and accelerate wear,even if there is a pulley cover.

This is what is i am talk about -->http://www.ebay.com/itm/BMW-E36-E39...ies&vxp=mtr&hash=item3f0a991ebc#ht_2270wt_952
I already confirm that is not the pulley and the bearing makes the sound. Before i changed the 2 bearing and pulley for this tensioner due to BM World bad works. After changed the belt tensioner to sound is gone. And due to the BM World bad works, i have 2 new pullies and bearings

That is mechanical tensioner..there is a coil spring inside that..it is possible that the sound is the result of coil spring rubbing each other when it vibrates..
another solution is..change to hydraulic type...then when the time comes, just change the pulley..(but so far I manage to change the pulley on the mechanical tensioner eventhough BMW sell the tensioner and pulley as one unit...)
