first - it's a thread I started to share the discovery of a simple solution for dashboard creaks. That was for my newest V6 Spider, which creaked worse than either of the older Spiders that I had.
Another success I have had is with silicone grease. This is sold in a tube and is usually food-grade lubricant for production equipment etc., so you will find it at an engineering supply store, rather than an automotive or hardware shop. Don't be tempted to substitute vegetable-base rubber grease (brake assembly lube), as I have found out the hard way about the embrittlement of ABS plastics.
With silicone grease on hand, try applying it under the plastic sill covers where they touch the clips, inside the car (these are the carpet holder trims), especially where they overlap the rear side trim. Also, apply some to the edge of the door trim at the corner where it might contact the outer plastic sill trim (the one with the bumped texture). They often rub at the corner.
Next I recommend taking the door trim off and removing the armrest pad - it comes off once you straighten its metal tabs. Clean all around where it goes on the door trim, and apply silicone grease liberally where it touches the trim. You wouldn't believe the difference getting rid of that creak will achieve.
Apply grease under any screwed-on fixing, particularly the pull handle and the door pocket. Apply grease right around the sides and bottom of the trim where it contacts the door, and even on the front surface where it may contact the dashboard. Then, of course, do it all again for the other door
The centre console is another area where large benefits are noticeable. Again, the screwed-on mountings are the main culprit, but also the surround for the gear lever gaiter and the covered box under the centre armrest (for phase-2 cars).
I'm delighted to report that after careful attention, my Gtv is creak-free, and it makes a huge difference to the refinement of the car.
