this is what happened to mine
the clutch relise bareing just fell apart and did what yours did. clutch went to the floor and stayied there
i have a clutch here for a 110 HDI as i thought they were the same for mine as it is yours but there not

would you want it??
if you do it your self dont even atempt it!! the box weighs a ton! but if you do make sure you ahve lots of help to lift the box out
another piont when you put the new clutch in and the box back on you need to get a tool to put in and thou the little hole on the relise arm and give it a good yank to engage the relise bareing onto the presure plate
or if you cant get hold of a tool or anything alike i took out my starter motor and put a bar in onto the arm and gave it a tap like that
(if anyone has a picture of a 110 HDI clutch i would be very greatfull of it to just double check the clutch i have is for a 110 HDI)
cheers
