Master or Slave - Clutch pedal no pressure

[Jezmondo71]

Hi I am looking for some advice on next course of action:

Came out to move my van yesterday and dipped the clutch which promptly went to the floor!

No obvious leak at the back of the pedal and all assembly looks intact, slight whoosh sound when operating the pedal by hand but won't repressure.


No indication of leak on bulkhead


Fluid level in the reservoir is unchanged (level is at the seam, no fluid loss).


Looking underneath where engine meets gearbox no sign of fresh fluid leak.


Parked on gravel driveway so no visible pool of fluid underneath (additional question - should there be some kind of engine cover plate/tray under the engine?)


Am I right in thinking if the release bearing/slave had failed I would have lost fluid in the reservoir and or the underside of the gearbox and so this is pointing towards the master cylinder failing?

Van 2018 6 speed manual T30 Kombi and is on 107k mileage, don't have a lot of history with it except belt and water pump changed by the garage where I bought it 18 months ago, they said it was a business vehicle and was regularly serviced but I have no evidence of this to refer to.

Is it prudent to order and swap out the master cylinder as a first step?

Could be a either.
But - this happened on my T4.
The fluid leaked into the clutch assembly and the whole clutch assembly needed replacing along with the master cylinder.
It is possible, if it is the same problem, that it leaked near where you parked up before you stopped. Just have a check within a few metres for a small clutch fluid patch on the road.

Bad answer and can't delete post.

Good luck anyway.

So after some more reading and discovering the reservoir has three chambers and you can't really trust the level, I topped off the fluid and tried the pedal again.

This time I was able to get some pressure back into the pedal and I can now see a drop of fluid appearing at the underside of the gearbox and at the photographed hole which I am assuming is some kind of breather/drain?

So looks like the slave after all and an expensive trip to my local independent

Same thing happened to ours…
Unfortunately I tried the master first to no avail. Out with the box and full clutch DmF later were mobile again
