Guys,

I seem to remember a thread on this a few months back, but buggered if I can find it...

As I accelerated from a standing start today to merge with traffic - I heard an almighty crack or bang noise from the rear of the car.
It sounded like a small explosion.
I thought I must have hit something but I can see no damage...

Does anyone remember anyone else hearing such a nasty noise on acceleration - and if it was a problem that needed to be fixed?
