Hello,
My 2003 s40 has a clacking sound (sounds like a loose plastic connector hitting something solid - maybe another plastic connector), coming from the interior front cowl/instrument panel. It only occurs when I'm driving on pebbly types of roads and not on smooth roads. It definitely is from the interior of the car. I have been going crazy trying to locate the exact location of the sound, but it is intermittent and I can't take my eyes off the road while driving. I only have 62000 miles on the car which I bought new in 2003. The rattle only started a few weeks ago. Can anyone help? Thanks.
