Happened about 3 months ago, as I accelerated away from a roundabout I heard a loud bang like something had snapped. Now I can put the car in any gear release the clutch and the car won’t move there’s a small rattling noise coming from the back of the engine/clutch area which you can only hear when the car is in gear and clutch released. Wondering if anyone has an idea what is wrong with the car so I can get an idea of how much this is going to cost me.
