    hey guys im having trouble with my AUS SPEC Sprinter (4AC) I have left the car unattented for a month or two and when I went to start it the clutch pedal felt like there was no resistance or pressure you couldn't make out the friction point at all pretty much there was nothing there, anyways when I went to engage it into first gear it wouldn't let me (let alone any of the other gears), as if the clutch wasn't releasing?!
    so then i turned off the car and attempted to put it into gear while holding down the clutch pedal to some how start in first gear but still it didnt work its as if the clutch pedal has no control over the clutch? I think its possibly the clutch release cylinder or the master cylinder but before i start ripping everything to try and find out the problem i was wondering if anyone has encountered this problem before or have any ideas on the issue? I really need this car to get to work as this was intended to be my daily driver thanks for your help

    Get under the car and loosen the bleeder nipple and keep added fluid till the nipple stops bubling.
    OR
    get some1 in the car to pump the pedal then hold it while you open the bleeder nipple tighten the nipple and tell him to pump it agian. do that till just fluid comes out no air (oh 1st top up the fluid level and just keep checking it)

    do what people above said, if the fork isnt moving simple its a master or slave cylinder,
    if the fork is moving but clutch isnt engaging thats more of a hassle, the clips could have popped off the throw out bearing and the fork is just swinging around in the bell housing,
    this happened to me once, replaced a clutch bolted it all back up, went to put my foot on the pedal and popped the clips off, had to do it all over again

    Just wondering as i'm not the most technically minded but a little rough diagram as to where all that is in the engine bay would be nice because i'll bleed the system but need a little direction as to where all that is thanks guys

    ok your slave cylinder and clutch fork will be under your extractors at the very back of the motor where it bolts to the gear box (best to look under the car)
    follow the line from the slave cylinder up the firewall to the brake booster and master cylinder with a cup on top.
    your problem will be one of the parts mentioned above,
    one other thing to do is get inside your car and look behind the clutch pedal and make sure its all connected properly there

    Ok me and my mate went to bleed the clutch system with no avail as it still wouldn't engage the gears because the lines still had 'air', the clutch fork I noticed was still moving but ever so slightly and I was told that if it doesn't move that means the clutch cylinder is gone but it appears to be working but i'm not sure as too how much 'movement' its supposed to have? So my other guess is the Master Cylinder maybe needs replacing? The other thing is when I rang repco to get the brake/clutch fluid they gave me DOT4 fluid but when I went to put it in the car it displayed that you should use DOT3 fluid but should this still have a negative effect to bleeding the air out of the system? Any Ideas?

    Dot 3 Dot 4 it wont hurt anything, so that is fine. Was there fliud in the resivior? If not then it has leaked out for some reason, You say the fork is moving a little, well it shopuld move over an inch I suppose. I would have to say that at a guess the Master has gone, mine had done the same when I bought it.

    look where the clutch pedal goes there should be a shaft going into the fire wall check if theres any fluid around there or from the line going from the resivior
