Audi A4 B7 2.0tdi clutch replacement

[@wesleyreynolds3820]

Greetings
Thank you for your video, as there isn't much out there I can find I thank you.
I have a 05 A4 B7 2.0TDI 6 speed manual.
I need to replace the input shaft seal as its leaking.
I acknowledge all the outer bolts holding the bellhousing in place as per your video, however I've read I need to remove 3 or 6 bolts through a hole at the bottom of the bellhousing before it will split from the engine.
Not sure it applies to my Audi model?
Do you perhaps have any info on this or videos

Hello, if you remove the bolts as per the the diagram in the video, the gearbox will separate from the engine.
