One of my intermittent rattles comes from the left corner of the dash.
I assume you know what causes this!

I believe this one requires the new clips. The sound proofing kit alone costs in excess of a hundred pounds. Although thankfully most dealers modify the existing clips to decrease the amount of play in the dashboard. A word of advice about the dashboard is that it has some temperature related contracting and expanding elements in it so you may have a totally different part of the dashboard creaking in the summer. I paid to have my dash fixed in June and ever since we've held the cold spell my dashboard has started to make noises again. I will ring the dealer and get it booked in due course. Any work carried out by a dealer will have a one year warranty and will get you through both the seasons to test your dash. Not that I am recommending you take your car to a dealer, just a heads up so that you can discuss this with your technician.
