The fluid level in the clutch master cylinder is only about 10-20%. Any attempt to top it up a bit results in the added fluid being expelled via the vented cap. When checked again after a long drive, about 300km's, it is back to the 10-20% level again. The handbook states the DOT 4 fluid capacity as 0.05L = 50ml. 1,663. Points. 446. Location. Limerick.

Hi all, I have a 2004 Fiat Ducato Motorhome fitted with the 2.8 common rail Diesel engine, that seems to have developed a clutch problem/slip.
