Unsure of the name for it
 

Sorry but I am unsure for the name of this seal.
It is where the driveshaft bolts into the gearbox with the multi-spline bolts
ATF is leaking from there, I have bought what I think is the right seal from audi to replace the leaking one.

I am just wondering how to replace the seal? As soon as I take the driveshaft out is the ATF just going to flow freely from the box?

Go here to the sticky for the Transmission Output Flange Seal.

:)

sorry its for the front drive shaft going to my drivers side front wheel
will it just be the same as a rear out flange seal.
i'll go take a picture of it just now! show you what i mean

You could try erwin, register (it's free) pay your 4 euros and input your shassis number and the whole process will be available to you.

My ELSAWin is plaing up again! Must get the latest version.

Isn't that the front driveshaft?

Yeah it is, will ATF pour out when I remove the driveshaft?

nope its gear oil in there not ATF

will it pour out? how do i go about changing the seal?

with the cv removed u should be able to remove the center bolt and pull the cup out, a bit of fluid will come out but not loads, then just prise the seal out and press the new one in, then near it there should be a 17mm internal hex fill point to top it back up at
