I am hearing a rattling sound under the car over even small bumps since I installed the DTS. I reached under there and grabbed the bar and it seems to be firmly in place, although I haven't taken a detailed look at it. I completed the install using the instructions, however I didn't use a torque wrench for the 13mm bolts or the 6mm bolts. What could be wrong?

I'm liking the DTS so far. Besides the obvious tranny benefits, the car is feeling a little stiffer now in the turns.

for your S4, but you do have to at some point ask the question: "why did Audi build this vibration/engine dampening into the system?"

<flame suit on>

I found that when I had one installed, I did note more precise clutch/shift characteristics but I also could feel a *lot* more engine/drivetrain vibration in the steering wheel and through the floorboards on a constant basis. I ultimately decided that the feature I liked the most about my S4 was the smoothness of its overall feel on the road and yanked the DTS out.

I found the feeling of relief after I did so well worth it and sold my DTS without regret. The slop in the drivetrain is intentional on the part of Audi Engineering and is an integral part of the behind the wheel experience that Audi intended.

The functionality of the DTS mod is entirely a personal choice as to what you want out of your car, but is without a doubt a compromise of the original engineering intent.

Then again, I didn't notice that much of an improvement with shifting either. I guess to quote S4MadMan, "YMMV".

but heck , even that gets dirty. :-D

I really don't think those two words are remotely the same thing, so I doubt what you're describing is what he's observing.

Also, no vibrations here.

I'm just a lazy bastard and have no excuse, except my new toy is keeping me busy! :-D

Enjoy!!

Almost any minor flaw in the car can result in a rattle if excited by vibration in the frame.

I agree that I did not experience rattles myself, but could easily see it as a possibility given the extra vibrations that the DTS bar was transmitting to the car frame.

As I said in my original post, the utility vs cost of this mod is entirely a matter of personal choice about what you want out of your S4.

Correct?

I know people that have broken the stock motor mounts without a DTS or snub

Andy Hedin mentioned that he wanted to ****** up the one's I got. I pointed him your way!

it's easy to see *how* vibrations may be transferred into the cabin. There is now a tie from the tranny to the subframe, isolated by (essentially) a large rubber bushing. If installed properly, that should not rattle. Anything remotely described as a "rattle" is likely to be very different from the vibrations you experienced.
