Annoying Rattle

[1NZYaris1]

For the last 3 months i have had this annoying rattle that sounded like it
was comming from inside the dash, Finally took it to Toyota Last week
and had them take alook at it while they where doing it's 30,000KM service.
Took them 5 hr's too sort the problem , but they won't tell me what they found
apart from one of the Rattles was a marble in the seat rail.
Sense then i have spoken too a couple of people at Toyota to see if they
could shead some light on the subject .
The result was they reacon it was the passenger air bag screws had fallen out
as this are not dune up tight ,so to allow airbag movement when it deploy's.
Any how it's all fixed now no more rattles and all covered by Warrenty
including the last of my free services
Thank you Toyota.
