about this?? They weren't much help on my 330 but now that I have the info about this valve, I could tell them about it and see if they know anything. This problem is really annoying and it was one of the biggest reasons I got rid off my 330. The X5 that I test drove did not seem to have this problem, maybe it did. I drove it a few times just to make sure but I never noticed it. It's very noticable in the X5 that I bought though.
