More 996 dash noise... Help- Just joined the group and new owner of a 996 Cab I've read through numerous of post / threads regarding wind noise. I'm sure someone has solved my issue however I would like to describe what I'm hearing to see if anyone may understand. Top is up, no noise (noticably) until I reach +70mph. At first, I thought the noise was coming through the dash speakers however I can't prove it. Just bought new speakers and headunit thinking this might help. It seems like it comes from the upper dash. When I get behind a tractor trailer going this fast (blocking the wind) the noise stops, I pull around to pass the noise is back. I've opened Windows, moved mirrors, taped down the battery box and a few other things just trying to figure it out. As I'm new to this group and the Porsche world, I need all the help I can get. CP

It could be the "windshield rattle" issue. Check this thread . There's a TSB for it - simple fix if that is what's causing your dash noise.

So all that needs to be done is buy the foam cord and smush it in the seal?

The instructions for the TSB (linked on the above mentioned thread) are clear. You just smush it in Of course, that may not be the OP's problem - but with some detective work he can decide if it's worth getting the foam cord. My advice is to turn up the volume or lower the top/window!
