Not quite sure which is actually causing the noise or both? on Youtube the disa valve sounds really clicky compared to mine and the video sounds alot different than in real life. but i was wondering if anyone can give me an opinion on either its the DISA valve going or if its actually the pully bearing?

Unplug the connector at the DISA valve and let the engine run ..if the noise goes away, if it does than you have bad DISA valve .but in The VID sound like you have both.

Thanks Tom, i did the disa valve check and i guess mine is fine i didnt hear a sound change. I guess ill try changing the pulley's first. RealOEM.com * BMW E53 X5 3.0i Belt Drive Water Pump/Alternator number 6 and 15 right? might aswell buy a new serpentine belt too but they come in packs of 6

Yii I have those pulleys laying in the trunk. I replaced mine with Turner Motor sport pulleys. If they are the same as an '02 and you want them PM me. And you can buy a serpentine belt at autozone.

X had 80k when I replaced them. Turner are pulleys are the shizzznit. They are more reliable as they are hard aluminium and take a lot of stain off the alternator.

I am guessing that's the one everyone has. Looks pretty sturdy.

That's for HP pulleys .... Not the one you need... You just need tensioner pulleys.
