So after a stupidly large speed bump, the rear diffuser part of the undertray is rattling loose. It is pitch black and wet out there, so does anyone know of a link to a diagram of the fixing points and what is it that fixes them? Bolts, screws or Allen bolts?
legend! It is the offside corner of the diffuser that has a 'twang' to it, possibly rattling against the other part of the flat floor under the engine.
