Haldex Coupling Oil Leak
Hi guys, Im new to the Audi World. I owned the 944 Porsche Tubro for about 17 years now, so I am new to these cars. We've purchased the car last month (Its an Audi TT Quadro Coup 225HP w/ a 6 speed manual). Like I said, I purchased the car last month, and I noticed there was a small dot of oil under the rear of the car. I jacked up the car and I noticed that the haldex unit (where it meets in the main prop shaft) was soaked in oil. It seems like the oil is coming from a seal where the shaft and the haldex unit meet, although I'm not sure. And if it is, does anybody knows the part number for that seal or bearing? I do not have the manual yet to get the parts number from it. I already ordered the haldex filter kit, but I do not want to change it until I fix this oil problem. Thank you in advance, and I know I will be probobly asking you guys more questions in the future about this car. Pictures are attatched.

Might be 7 years later... but look up the part here - select the correct part of the globe first:

There aren't too many of us that can tell where a leak like that is coming from without having the vehicle present, jacked up or on a hoist. But as a SWAG (Super Wild-*** Guess) I'll go with a loose filter on the Haldex clutch unit.. Or a seal on the electric motor pump. No chance of a cracked case, correct? I cannot see it due to the unfocused photos.

I am asking OP here, because his oil leak looks identical to mine.
So he, most likely, have the answer.
It's seems to me like people keeps the answer to themselves if the issue is fixed.
Thanks for taking the time to give me your SWAG's
It's very hard to see in this area, but i does look pretty dry around the pump and filter.

Ulrik, two years later, I'm having the exact same problem. I changed the o-rings on the pump and replaced tighten the filter, wondering where it's coming from.
Looks like I need to pull down the Haldex to get a good look.
What did you come up with?
