Hi guys and gals. I was driving my car on Saturday, parked it up, then went to drive it again a few hours later and this very worrying rattling / banging started to happen. It sounds awful, almost unsafe. It's coming from the read of the car, sounds like it's coming from the boot, but it's on the outside of the motor. It's more obvious when I go over bumps. I've had it up on ramps and have and checked the underneath, given the exhaust a shake and a prod and it's not that. It's not the jack in the boot either. I can't see anything loose and I can't replicate the sound unless the car is moving. https://soundcloud.com/ccannon1210/whats-this-noise It's a mk2 FL Cupra.
