I've had my 08 Cayenne S for about a week now. Every time I'm at around 1000 RPM the floorboard feels like it has avery slight vibration. It's audible too. It sounds like your steering is low on fluid, kind of a "waaaauung" noise. It's not the steering because it does it when I'm not turning the wheel. Could it be a component of the exhaust touching the body of the car? Any other ideas?

Or is this normal and I need to get used to it?

Thanks.

 

If nobody knows what this is then it's not normal, right???
