Loud hissing sound when pressing the clutch pedal

As other listers have already pointed out, I also think the TOB is on its way out.

Also BTDT on a VW QSW I bought with a bad TOB. When I got it, the TOB was on its last leg, making a very loud grinding noise in the bell housing area as well as a subtle vibration on the clutch pedal as soon as this was engaged.

When I separated the bell housing from the engine block, the TOB fell apart upon touch. I was lucky it did not do any damage to the fork, guide, input shaft or any other surrounding parts.

I imagine your vehicle also boasts a pilot bearing and, if so, should replace while everything is apart.
