KNOCKING NOISE FROM UNDER DRIVER SEAT?

I get a minor knocking noise/sensation when i first start and drive my R. Its as if there is something physically bumping the floor under my feet at the pedals. It only happens the first time i drive it for the day, and only in first gear. any ideas what this could be? <p>In another, perhaps related issue...i'm feeling the slightest "slippage" when clutching into first gear. i cannot tell if its a mechanical issue or has something to do with the cars ECU or suspension.<p>this does not only happen once, but perhaps a few times before it goes away for the day. the possibilities seem endless...<p>any feedback would be appreciated! <p>

you SURE its coming from under the driver seat?<p>if its happening right around 10mph, its your ABS performing a self-check. its completely normal.

now that you mention it, it was slightly more noticeable in the cold.<p>if you are concerned and don't think that this might be it, take it to the dealer to be sure.<p>

Did you do an aftermarket exhaust system?<p>You may want to check to see if your exhaust is hitting your driveshaft.<p>Park it on a downhill incline and let it idle. See if you hear/feel the same thing.

that wouldn't explain him only hearing it the once and the first time he drives the car.
