I have a four month old Peugeot 208 which has got an annoying rattle coming from the driver door area or front pillar. Because the car is new and is in warranty would I be in my rights to ask the dealership to try to find out what's causing this rattle and fix it?

I had a new Toyota Corolla which had a rattle behind the dashboard. Toyota dealer took it in for a day and fixed it, no quibble, so your dealer ought to do the same. Good luck!

Had a similar experience with the dashboard on my Golf.

The main dealer was only too pleased to claim the warranty work and eventually mounted the whole dashboard on rubber grommets . Net result far worse.,! Never was fixed !

I have noticed the lengths that Toyota go to to eliminate rattles through engineering them out in the first place ! And a sun visor that actually stays exactly where you want it !

Most certainly. We had a similar strange rattle, especially when going round corners. It turned out to be a stray seat belt bracket bolt rolling around in the depths of the floor/sill area, necessitating much removal and replacement of the interior trim! Carelessness or malice? I remember reading possibly apocryphal stories of disenchanted British Leyland workers leaving beer bottles in bodywork spaces.
