Just noticed a nasty rattle at 2-3k RPM today. Sigh.
It sounds just like the DISA rattle on my dad's car. Problem is… I replaced my DISA only 4 months ago.
I can't quite differentiate where the sound is coming from, and my iPhone can't seem to pick up the rattle in video.
Any ideas?
Can I unplug the DISA and run the car at 2000 RPM as a test? If it goes away, it's the DISA. If it's still there, it's not the DISA. Does that work?

Disa works off of vacuum so if you unplugged the vacuum hose I imagine it would no longer serve its function.
However if the flap or pin itself have failed it would still make the noise I would think. Honestly may be easier to just pop it off and take a look at it.
How did you replace it? Just a new unit from BMW or the rebuild kit? Can't remember who sells the rebuild off top of my head.

I replaced it with a brand new OEM unit from ECST.

So it's DISA and not VANOS?

Based on sound, that's my guess. But I'm not 100% sure.
Is anybody familiar with the differences?

I would think you'd be able to tell with your head under the hood (and localize it), but I can't be sure. Can someone confirm if you can feel the vanos rattle if present?
Big Earner
Not sure if you can feel it, but my suggestion would be get a mechanics stethoscope and have a listen while someone revs the motor.
That should make it obvious.

I've never heard of the disa actually rattling but I could be mistaken. My car has incredible VANOS rattle at about the same rpm. Have you installed new seals or an anti rattle kit yet? I plan to have mine installed soon.
