please could someone tell me where the clutch bleed nipple is, i read somewhere that you need to remove battery tray, to get to it, i have done this and can not find it

It should be at the end of the flexible hose going to the slave cylinder on top of the gearbox and should have a little rubber dust cap on top.

it maybe a slef bleeder in which case what you will need to do it remove the battery tray, locate the slave just under it (the one with the rubber push rod cover) pull the pin connecting the fluid pipe to the first notch and have some on pump the pedel down once down pop the pipe in and hold it tight, have your assistant lift the pedel and keep repeting this process until happy. this is how i did mine.
