Just purchased my 07 330i Touring M Sport 37k miles,
I love it though until a few days ago.
I took my friend out for a little spin
But now there is a definate rumbling/Judder/light knocking when around 2-2500 rpm or about 30-40 mph.The sound/noise dissappears once above the revs/mph.
Its deffo a new noise from a usually silent car.
The car did come with warrenty.
Any help reply appreciated
