I’ve been having a strange groaning noise in my 04 330. Sounds just like Chewbacca. At first it was only when I first started the car but it got progressively worse. I swapped the power steering pump and CCV system a couple months ago so I thought maybe it’s the DISA valve. Swapped in a used one I had and there was no change. I bit the bullet and ordered a newCCV and all the tubes. Swapped it all out and no more noise. So don’t buy cheap CCV parts. This last replacement was OEM. The one I just replaced was cheap eBay

The moral of the story: you get what you pay for.
Out of curiosity, did you replace it with the standard one or the cold-weather version?
