Hi all -

I've towed a U-Haul 6x12 trailer many times with our allroad (2.7T, 
6-speed) on 200-mile trips with no problems. I do try to avoid backing 
up uphill, only because my backing skills aren't 100% ;) and that can 
stress the clutch a bit (at lest when I'm the one doing the backing;) .  
And yes, this *is* the same drivetrain as in the S4, *including* the 
6-speed. So I'd say the drivetrain shouldn't have any problems.

However, the allroad was designed to tow a trailer, and in fact we have 
the Audi-manufactured trailer hitch for it. The self-levelling 
suspension is great for towing as it compensates for varying tongue 
loads, and the factory hitch ties into the unibody in factory-approved 
locations. I personally would *not* put a hitch on our S4, especially as 
we have another vehicle which was designed with towing in mind.

My two cents,
- Bob T.
