Golf mk5 slave cylinder

[Earlmac]

HELP!.
Watched a lot of YouTube videos regarding the slave cylinder and to change it . However my Golf Mk5 doesn't seem to match any of the videos . All say under the battery , onto of the gearbox. Which I see where it should be however its not.
Anyone have any idea where it is ?

Which slave cylinder? The clutch or the brake? On the 6 speed manual, the clutch slave cylinder is internal to the gearbox. You can see the connection to it on your picture, in front of the gear linkage

You cannot replace it without removing the gearbox from the car. Are you sure it's bad and it's not the master cylinder (on the pedal)?
