Hi All
Does anyone have any advice on the cause of the following problem, I drove to work today and the effective point of the clutch slowly deteriorated to the point where I was unable to shift into any gear from neutral at the lights. Pumping the clutch in neutral seemed to restore function. I made it to a car park but haven't had a chance to inspect anything. Any suggestions about what to look for or the possible base cause of the problem is much appreciated.

Leaky slave cylinder? check fluid? clutch pedal adjustment? unfortunately process of elimination!

As above. Check fluid level firstly. Sounds like air in the system or a leak.

When bleeding the most effective way is to gently pressurise the reservoir to bleed.

Master or slave cylinder leaking internally so may or maynot leak to the outside. Check firewall under clutch master cylinder inside cabin and under slave cylinder if it has lost fluid from reservoir.

Apart from the advice already given.
How long since the fluid was changed?
Does it look black in the reservoir? If so it needs changing.
 
Google up 'hygroscopic'

Hi DPL,
+1 for Master Cylinder. I had similar symptoms recently.
Mechanic fitted overhaul kit & bled system. I am still not sure that it is perfect.
Maybe Slave Cylinder rubber is passing as well. Bleeding is apparently something of a challenge.

I find bleeding is easy if you use a suction pump, but you need to be sure you don't run the tiny reservoir dry. 

I bleed using a one man bleed kit & use a regulated low compressed air thru either of the rubber cap tops.  Works great on both clutch or brake bleeds, & takes about 5mins in total.

I had similar symptons before and it turned out to be a slave cylinder leaking internally

Yep - it was the slave cylinder for me, and what a bitch of a thing it was to replace too.  Pull the boot off with your fingers and see whether you have fluid spill out.  If so, then it's time to replace it.
