Generation and Equipment Verification
Fitment guidance for 8T8 807 521F. Review the application in the parts catalogue and then measure or photograph the removed panel. A facelift boundary or market-specific trim grade may require a different cover. That comparison gives the workshop a clearer basis for a pre-paint decision.
The rear location on 2013 AUDI A5 (sport version) should be reviewed as follows: Check the side retainer areas, upper fixing line and lower mounting pattern.

Handling the bumper-aero component Before Installation
Receiving note for carton AD02003-031. Allow the panel to rest in a supported position after unpacking, especially when transport packaging has constrained its shape. Compare the relaxed outline with the original before making a fit judgement. This evidence belongs in the same approval file as the vehicle photographs.
Pre-finish check for 2013 AUDI A5 (sport version). Trial fit with undamaged vehicle-side hardware and avoid forcing clips into position. Excessive pressure can hide an incorrect reference or create permanent deformation. This sequence keeps catalogue selection separate from cosmetic preparation.
Export Purchasing Notes
A quotation for 8T8 807 521F should reflect this guidance: Request packing dimensions and gross-volume estimates before finalising freight. bumper spoilers and air deflectors can be lightweight but consume substantial shipment space. A dated photo record makes the decision easier to review if questions arise later.
The 3 square images attached to AD02003-031 support visual review. Confirm whether samples require workshop trial fitting before bulk release. A documented approval stage is valuable when supplying several regional vehicle variants. The completed check supports a traceable discussion between buyer and supplier.
