E39 M54B30 engine CCV (general question)

Hi all!

Do you know if the M54B30 engine has an issue with the CCV going bad?

Is the CCV known to go bad and need replacement every certain amount of km's?

I am asking because the CCV on my car was replace in 2012 with the cold weather package CCV, the car then had 150k on it. Now the car has 270k on it and I am just wondering if after 120k the CCV needs to be replaced.

I am trying to rule out (if possible) the CCV as a culprit causing a rough cold start.

Any helpful feedback is much appreciated!
