DUDE !!! You might have saved me !! I got a 96 A6Q 2.8 it blew gear oil out the transfer case which you start tearing apart around the 8min mark . I'm guessing it pushed out the blue breather cap ?! Although it doesn't seem like there was/is any lube in that section from the vid (looks super clean). Any Info would be great (currently 173k on the odo)

So, what problems did you see? 500,000 is a lot for a ZF4HP18 in an UrS.
