I've never bled the slave cylinder, and it still has the CDV.

Clueless question--What is a CDV?

Clutch delay valve- (big e39 540im issue)Originally Posted by Gayle
Heres a good description of what it is in theory and why you would get rid of it
Check it: http://www.zeckhausen.com/CDV.htm
I know it's not from an e34, and I've screwed up all the other links I've given today, so go easy on me Bill.
P.S
no affiliation- just had the link.

The Clutch Delay Valve.
Designed and installed to release the slave slower and, supposedly, to prevent driveline wear. All it actually does is accelerate it. I'm told that 150k+ used to be typical for a 540 clutch, whereas some claim they only last 60k now. Everyone I know removes them, if installed.
best, whit
Is the 540 the only E34 with this CDV? I am not sure my 535 has one!

The 540 6 speed is the only E34 that I have ever heard of having a CDV.
