Questions you thought were too dumb to ask E53 edition

On my E53 4.8 :
Close your moonroof fully (close sunshade also). Hit the moonroof button once upwards. Does your sunshade split in half like this? Moonroof goes in tilt position while sunshade splits.

I'm asking this cause I never noticed before and on my wife's E70 , the sunshade doesn't split in half with this function , it only opens from the front a few inches.

Ditto Vein, this is normal for the e53 Pano sunroof. It was definitely a departure from the way the regular sunroof's shade panel operated when the sunroof is in the vented mode (front of shade panel moves back a few inches). From what you describe about the e70...looks like they went back to the old way.

Bought a 2004 X5, 3.0i w/155K. Beautiful car but has issues. I've been correcting one by one.
My issue is the AM/FM radio isn't tied to the ignition key. It's always hot. You have to manually turn on and off.
When on, it will turn off after 20 mins on it's own. If you press the volume/on/off button it will come back on for another 20 mins.
And unable to set the clock on the radio. I had the LED strip replaced.
Also the number 73 or 74 10a fuse in the back (for the radio) seems to have a short. Every time I a new one in it blows the fuse (only took me three to learn something is wrong).

Okay, I'll take a shot... where is the PCV? Thinking to check it and swap out, since I've always done that on used cars soon as I get 'em home, along with the thermostat. On my previous cars it was always easy to find. With the battery under the spare tire, I'm almost scared to ask. Those germans are so darn sneaky! :P

There's no PCV because the Germans replaced it with a CCV.

Lengthily video walk through of CCV on M54 in an e39 which I hear is same for the X Replacing the BMW M54 Crankcase Ventilation System, Part 1 of 3 - YouTube

What I found when buying the parts for CCV replace is that there are two kits: normal and cold weather. The cold weather has insulation on he outside.

Also this was posted in these forums few days back:
