I am picking up a 2002 Audi Allroad 2.7T this week and I have a few questions regarding the drivetrain.

I did a bit of a search and didn't come up with much. I am wondering if anyone knows if the Allroad comes standard with a limited slip rear differential or if not whether there is one available for the car. Is it something I can get straight from Audi? I had one as standard on my AWD Volvo Wagon and it made the world of difference in the heavy snow we get here in Lake Tahoe.

I also don't know much about the AWD system on the newer Audis - is it a Viscous Coupling setup, electronic engagement, or something else? If someone has a diagram of the system that would be great!

Any information is much appreciated.

Thanks,
John
