Just spoke to the garage looking at my Landy and after a lay down to recover........
They say it looks like the slave cylinder is leaking.
It will also need a clutch kit, Possibly a master cylinder if the seals have collapsed as a result of the slave cylinder leaking. They won't know until they try and bleed the system after replacing the slave cylinder. It might need a new flywheel something or other.
Worst scenario about £1350.
If I didn't need it for getting to and from work, I would do it myself over a week or so, but some of the hours I work there is no public transport and 20 miles each way is a long way to walk.
I suppose it is worth doing. Although it is a 2006 model, it has done less than 42k and did run well and has always been reliable.
