Today we (my mechanic and me) had some free time and decided to go
through the removal of the CDV.
For this purpose, I ordered an empty CDV; a valve with its internals
removed.
The source and information:
http://www.zeckhausen.com/CDV.htm#Theory%20of%20Operation.
Good communication over e-mail and fast delivery from USA.

This is what I received in the mail:
As you can see, the CDV doesn't have anything inside.. It's just to
be bolted in the place of the old one thus avoiding bending the
clutch lines and manufacturing custom made bolts/nuts to fill the
gap.
I had the luxury of lifting the whole car in the garage and I could
easily work. If you are attempting this, a good set of jack stands
is a must.
Car from below. The CDV is easily seen without removing any covers.
Just next to the gearbox under passenger's side.
After replacing the CDV, I had to bleed the clutch from the bleed
screw. It's good to have one person in the car pumping the clutch
and another person under so that when all air comes out, to tight
the screw. Pumped the clutch 3 times.
I used this pair of clamps to prevent clutch/brake fluid running.
The removal of CDV is dead easy. I don't remember the key sizes but
I used to pair of keys, one to hold it and one to unscrew it. Placed
the new one in the same manner.
Finally, don't forget to top-up the brake/clutch fluid which was
lost during bleeding. I used the OEM BMW DOT4.
Now the good part...
THE RESULT IS AMAZING!! I CAN SHIFT THROUGH 1st, 2nd GEAR SOOOOOO
SMOOTH I CAN'T EVEN FEEL IT!!!!!!
Can't recommend this mod enough!! I just wish I done it earlier!!
