Bought one from dealer k, though not sure how damage on mine occurred, but top was split (wife denies hitting anything)
Part Number: V5G0 807 287 H9 B9 - S/O Bracket
Bought the fixing rivets too as its easy to lose the center pins as pop them through to release the tension on the rivet - VN 038 549 4 - Rivet (pack)
£24.20 inc VAT
If not seeking to replace like for like, then be careful as the holder is secured by the rivets directly to the bumper IE: Drilled holes.
Its a 10 min job but could be an hour if attempting to retrieve the rivet centers as they do pop right through into the engine tray - pay for new pack of rivets so much easier.
