BMW, in their great engineering wisdom, has often decided that we aren't fully capable of controlling clutch engagement on our own.
So they put a valve between the Clutch Master Cylinder and the Slave that restricts the flow of fluid. When you move the clutch pedal, it actually slows the release of the slave cylinder to not be completely linear with the clutch pedal movement. Thus "Clutch Delay Valve"
Coming from 22 years driving Miatas where the clutch is hard-wired to the pedal (especially after you swap out the normal clutch line with a double loop, for a direct SS line) it's a bit odd to have it be so laggy
I've adjusted, but it's annoying not to be able to replace the CDV with one that's been bored out (no restrictions) so it acts like a hydraulic clutch system should, and pedal movement is directly reflected in pressure plate movement.
It used to be external and you could just swap it for one with that was modified so it provided no restrictions. In the 2 series, it's been integrated into the bell-housing/clutch, so not an easy external replacement/fix/hack/whatever.
