I think its weak.
I guess its hit or miss and your driving habits
make the diffirence.
I believeits not worth the price you have to pay if it breaks and warranty does not cover it.
One thing is for sure where audi put the turbo's on top of the tranny its horrible cause when they get hot , tranny/close to front axles gets hot and thats a bad design.
I mean how the heck is it going to get ANY air near you knees and all that heat rising close to them :(
The xtended warranty till 2011 or 75,000 miles really helps and its transferable.
Pic above.
Also the Audi RS6 turbo is barely adequate
actually.
That is my engine and tranny being took out so they can replace turbo's and transmission a few weeks back.
Now @ 42,000 miles and also replacing front brakes/rotors and new PS2's all around I love it.
