Hi - at long last i've had chance to have a go at finding an annoying noise in my car which is caused by a very specific bass-line of sound from my BOSE stereo system. It manifests itself 'inside the A-pillar trim, but only when the door (obvious place of vibration origin being the speaker in the door which even on its own with other turned off creates a lot of vibration) is closed, ie, pressed tight against the door frame so the vibration can be transmitted into the A-pillar. OK so far. Methinks, ahh will be something lose within the A-pillar panel. So managed to pull the trim off - bit awkward but easy when you know how! And found that all that is under there is some bundled wires and a curtain airbag - and upon close listening - not the cause of the rattle. So i'm now at a bit of a loss, without actually going to Audi to have it looked at. Know whats going to happen there. A they will tell me something daft like its actually the exhaust rattling and it is being trnasmitted through the car body. And (B) My car will in some way be damaged (even if its some tiny mark somewhere this WILL happen). Anyway i digress - i can't work out where else its coing from but it certainly is and loud as life - i can hear it over loud bass-heavy music. Seems to be coming from deeper, ie, inside the metal part of the A-pillar but then this seems to be filled with some sort of foam - anybody know if there is anything within the metal A-pillars that could rattle? Its definately not in the door, as when the door is open, its fine, its only when the door is closed properly and tightly against the door frame.
Jeezz i thought these were supposed to be 'well-built'!
Any ideas anyone?
