General Clutch Bleed

[Donnieducato]

Hello All,
I just bled the clutch on my 2013 JTD 2.3 Ducato 130 multijet and now the hydraulic pump wont prime, do I have to hook it up to a diagnostic tool for it to reset ?
Here's hoping

By "hydraulic pump" do you mean the clutch master cylinder and that the clutch pedal is soft /not disengaging the clutch properly?
If so I would first try using gravity, by opening the clutch slave cylinder bleeder wide, whilst keeping the brake master cylinder reservoir fully topped up with fluid, assuming that it is what fills the clutch master cylinder from a hose part way down the brake reservoir, do this until you can see no bubbles coming out and retighten the bleeder. Let it settle then gentle try the clutch pedal a few times. Do not pump vigorously when doing any bleeding as this just aerates the fluid making it harder to get air out of the system.
Hopefully this does the job. Failing that I would use a air pressure bleeder that fits on top of the reservoir following instructions carefully. Do not use a vacuum operated bleeder as if cylinder seals are weak this will make it worse by collapsing the cylinder seals allowing more air in.
All this is assuming the cylinders are in fair condition, not old and leaky.
I have just read your other thread about Comfort system, I thought from the original thread you had a conventional clutch and gearbox as you didn't mention Comfort.
Others here will be able to give you more relevant information regarding that setup.

Yea sorry about the lack of info there.

There have been several threads in the past with Comfort/semi auto issues, so you are not alone, which may be of helpful advice.
I tend to steer away from any form of auto gearboxes, the last time I had my head inside one was a Borg Warner 35 used in Jags, around 1970 at college if I recall.

I see you asked about the MES and Elm327

A relevant thread..

If you still need that info..

The MES homepage has

A LONG supported vehicle list

On your model of Ducato.. there should be ALL the modules it connects to AND key telling which cable for what

History tells me anything 'special like an Autobox..or Folding roof..

Needs a coloured adaptor

Update on this, it turned out the pump motor and relay were burnt out a relatively easy but not cheap fix

As I have become aware since this problem arose it is actually a manual gearbox with a Selespeed CFC 348 hydraulic clutch of which the motor and relay had both burnt out
