Not another oil leak!

Hi guys,

I the process of taking my 200tdi out in order to change the clutch but whilst its out I figured I might as well see if i can sort this oil leak out too.
Has anyone had a leak like this before or could tell me the cause? Would be good to get whatever parts I need here before I pull it out so I can get the job done as quickly as possible.

Many thanks in advance.

remove flywheel housing and fit new gasket err1440 ,rear main bearing cap tends to leak

Does that mean i would be well served to replace the main rear bearing cap too? Or is this not something that is quite as straightforward as it sounds?

Mine leaks around that spot too, thinking it's the rear end seal. Have to pressure wash it so I can be sure where I see it's coming from.

Mine only leaks when I drove it around the block and parked it, leaked a bit and then stopped all three times.
