Hey, just removed the CDV from my 335i today. Very straightforward and much simpler than the CDV removal from my E46 M3. Steps are as follows:

1. Jack the front end up and put it on JACK STANDS. Do not get under a car that is supported by a jack only.

2. Remove the 6-or-so 8mm screws that hold the center underpanel in place. This should be the one under the transmission, with the air vent in it.

3. Release the clips from the CDV inlet, and the CDV outlet (actually the regular clutch line adapter). These clips are just small, paper-clip like clips that you'll see on some electrical connections (at least on older BMWs).

4. Remove the CDV, and install the rubber clutch line directly into the CDV adapter. Replace the spring-clip on the adapter.

5. Use a 7mm box key wrech and a friend to bleed the clutch valve. Be sure to pump the clutch a few times to get the air out of the system and into the bleed valve inbetween bleed sessions. 2-3 times should be ample.

6. Replace the aerodynamic underpanel.

7. Lower the car, and enjoy your new CDV-less shifting!
