I have mine scheduled to be done by my indie next week.

My '04 has 180lk on the clock, original CCV. Light vacuum when the oil filler cap is removed, oil consumption is variable at 800 - 1000 per quart ( I sure hope that gets better!) and there is a subtle ringing "tambourine" like sound emanating from the engine bay I associate with the CCV. I have the OE BMW cold weather parts for this, but no time or inclination to do it myself. Not looking forward to the bill either, but well, it does need to be done.

I have the same 'light vacuum', just barely noticeable, have to pay attention removing the cap to notice it. My Oil loss/Consumption is much higher, but I know most of it is leaking out..

This Tambourine sound you refer to, not the DISA valve rattle is it? I ruled this out on mine, but have an odd vibration like noise I can't seem to track down that seems to be coming from the same area, would be nice if it is the CCV..

Nope. I had the DISA rattle, installed a new OEM DISA maybe 500 miles ago.
