Rattling at speed

[Spooky]

Anyone else experienced a rattle/vibration behind/under the dash at speed?
It becomes noticeable worse at 70mph+, I can't figure out where exactly it is...I wonder if something is loose underneath.

Next step is to book it in to get checked (and the passenger seat creak at the same time)...

anyone else heard anything similar?

Have you checked the flaps in the scuttle panel? The offside (driver's side) one gives access to the brake fluid chamber, and the near side one is empty beneath it. Lift the bonnet and they are immediately below the windscreen. The clips that hold them closed don't appear to be very definitive in their latching. Just a thought.

Good call.
Will check it in the light tomorrow
Ta!
