CCV Replacement on an M54 (E39)

I successfully removed and replaced the CCV and all hoses using the DIY procedure posted by Fudman. This job was a royal pain and took about 12 hours; 1/2 day saturday and full day sunday. I had two areas of difficulty. One, removal of the hidden 10mm nut behind the intake throttle body securing the electrical junction box. I bought a 10mm socket w/swivel and was able to final get in a remove. Second was the re-attachment of the connector-line hose to the top port of the CCV. I had to modify the new CCV component as described by Fudman-- reduced the stab/twist locking detent from 1 inch to about .3 inches work for me as well. I used a 1/8 inch diameter endmill type cutting tool in my Dremel instead of a sanding stone. I labeled all of the electrical cable assemblies with file folder labels- worked great. Great write up by Fudman-. Thanks, BMW657.
