Hi All,

I have a very slow, small leak coming from the area right under the shifter. It's a light lubricant. Anyone have any idea what it could be? Is the center Torsen diff right there? I haven't jacked up the car to crawl under as yet.

TIA

Center diff seal from the output shaft I bet. Having mine replaced in a couple weeks. Seems to be a weak point. I think the seal is $38 bucks.

Thanks for the near confirmation of my suspicions.

Any idea yet what the labor cost or time is?

My shop is doing it for 1hr labor.

You have made my weekend! What an enormous relief. I was so worried it would cost thousands...

Dropped in to see if the RS6 get's much attention here...get my 1 post in per year: 11 total

Yes, it's the 'rear AT' seal; center diff.

Curious what the actual labor in terms of hours that was charged? The process is tedius and almost requires 2 people. It's crucial to correctly align the prop shaft. I seem to have to realign them whenever someone else has "been in there".

Published flat rate times are about 3 hrs, and it will take that amount of time. That doesn't include changing the gear lube, which absolutely should be done at the same time. FWIW, i use 85-140 Amsoil in my RS6 as it's tuned and is very torque rich (as any RS6 owner knows). I can recommend specifics for the entire car (ask or PM).

Hope to see the RS6 on topic more often. Check out 'Audi RS6' on FB also.

I was charged 1hr, but you're right it is a 3hr job.
