Something has happened my car. Up to 70kph everything is fine. Above that I am hearing wind noise behind the glove box. At 100 kph I get this flapping/banging noise which stops any 120 kph. All at the wheels/suspension seems fine. 2007 Range Rover Sport TDV8 HSE

Mmmm.... hard one to diagnose as it could be a lot of things, however one thing which always happens to me if I get the window screen changed is they never replace the plastic clips on the side window trim which they have to take off to replace the screen, which would allow air to get underneath it as it's not held tight.

May be worth a look... just light pressure with your finger tips where the trim meets the front screen, if you can lift it off the screen then that probs your issue.
