I purchased a 2009 BMW 318d M Sport about two weeks ago, and in the last couple of weeks I've been noticing a weird vibrating/rattling noise coming from the middle of the dashboard. I recorded a video of it happening this morning and have uploaded it to YouTube, the link is:
The noise only happens when the car is:
o Either stationary or moving slightly (at traffic lights or a roundabout)
o When I apply the brakes firmly it happens constantly (as you can hear in the video - but it does still happen when my foot is off the brake)
o Only happens when the car is in drive - seems to be fine when in reverse or park.
o I noticed today that it starts to happen within five minutes of any journey, so not an instant thing.
The car itself is driving absolutely fine, I purchased it from Stratstone and it was given a Service and MOT before given to me.
Any idea what it could be?
