Its fairly easy providing you are nimble or have a lift/ramps, anyone could do it really providing you have a little knowledge of
Theory of Operation - What is a CDV?
The Clutch Delay Valve (CDV) is a one-way restrictor installed by the factory between the clutch slave cylinder and clutch master cylinder, as shown in Figure 1. It "delays" the engagement of the clutch, much like old record players used a damped tone-arm to gently lower the needle onto the surface of a record.
Because of this valve, no matter how quickly you lift your foot off the clutch pedal, the clutch engages the flywheel at a constant (slow) rate. In theory, it can save the driveline from shock, were an inexperienced (or immature) driver to dump the clutch at high RPM. But in practice, all it does is prematurely wear out the clutch and turn experienced drivers into people who, despite 20 years of practice, cannot shift gears smoothly. During parallel parking maneuvers, the delay can be infuriating, causing constant clutch slippage. And during hard acceleration, the large amount of clutch slippage can greatly shorten the life of your clutch. During normal, sedate driving, the shift from first into second gear is often jerky, leading passengers to question your skill.
Ok so what do you need?
1) Set of decent spanners particularly 11mm x 1 and 17mm x 2
2) CDV Delete (Although not essential can be done without)
3) Mole Grip (Or G-Clamp if you cant find moleys)
4) Jack and stands
5) 2.5 hrs spare time
6) A light if your working in the dark like i was
7) Something to rest on as you will be under that car for a while
8) A catch pan and rag
Ok so you need to start by jacking up the car - i used a jacking point just behind the rear front wheel and a piece of 2 x 4 to spread the load. An issue i had was that i needed to raise the car first before the jack would go under, I used the standard car jack to achieve this. I also did the rear on the same side using the rear subframe as a jacking point.

NB - Be careful not to round off the 11mm union as it is a fairly soft material (Flared Spanners may be a better option). You may also need you catch pan and rag as a little fluid may still come out as you will se in the second picture. This also shows how very little flow the CDV allows through.
