Does the B9 S4 have a Torsen, or does it use Audi's crown gear center differential?

Hey G Man, chill please. This pattern of harassing users must stop now. Thanks.

Torsen

The TCU+ Transmission tuner fixes that among other things. From you're describing, it sounds just like a standard S4 transmission.

Quattro generation VI

Audi debuted the 6th generation of quattro in the 2010 RS5. The key change in generation VI is the replacement of the Torsen Type "C" centre differential with an Audi-developed "Crown Gear" differential. With the new "Crown Gear" center differential, up to 70% of the torque can be applied to the front wheels while up to 85% can be applied to the rear wheels if necessary. The net result of this advance in quattro is the ability of the vehicle electronics to fully manage the vehicle dynamics in all traction situations, whether in cornering, acceleration, braking, snow or in any combination of these. This system was later adopted by the A7, latest generation of the A6 and A8.

As far as the clucking problem, it sounds like too much play in the propeller shaft or its related components.
