BMW Genuine M Performance Rear Diffuser Carbon Replacement Fits F40 51192467258 Removed from my f40 m135i damaged (see images) a crack to the right side of the diffuser, it has not gone all the way through, this can be hidden well with a smart resin repair and polish back to gloss. Mostly hidden under the edge. Other than this is in excellent condition. You must check compatibility with the BMW part number and fit for your vehicle before purchasing.
