Product details

8W0 807 521M RU6 anchors the quotation process to the OE code, installation position and stated vehicle. For 2020 AUDI A4, AutoParts tracks the requested rear bumper air deflector as AD02003-013.

Panel Geometry Confirmation

Fitment guidance for 8W0 807 521M RU6. Record any non-standard accessories or styling packages. Add-on trims and sport equipment can affect the outer profile and the openings required in the supplied part. A dated photo record makes the decision easier to review if questions arise later.

The rear location on 2020 AUDI A4 should be reviewed as follows: Before surface preparation, position the unpainted cover on the vehicle and examine the gaps at lamps, grille, fenders and tailgate or bonnet boundaries.

Panel Integration Around Lamps and Grilles

Functional context for 8W0 807 521M RU6. The component is a finish-critical exterior item, so packing, storage and workshop handling can influence the result as much as catalogue selection. The same information helps receiving staff identify the correct carton and panel.

Its suitability still depends on the specific vehicle and equipment configuration. The purchase team can use the recorded result when confirming the order line.

Body-Shop Preparation Notes

Receiving note for carton AD02003-013. Inspect the back surface as carefully as the visible face. Mounting tabs, clip seats and bracket interfaces determine whether the bumper-aero component can be installed without stress. This review is especially useful near model-year or equipment transitions.

Pre-finish check for 2020 AUDI A4. After unpacking, compare left and right symmetry and inspect the corner returns. These checks help identify handling distortion before the panel reaches the paint booth. That comparison gives the workshop a clearer basis for a pre-paint decision.

Commercial Approval Before Bulk Supply

A quotation for 8W0 807 521M RU6 should reflect this guidance: Quote the item code on every revision of the enquiry. Traceable references reduce confusion when several front, rear, upper or lower covers are reviewed together. That comparison gives the workshop a clearer basis for a pre-paint decision.

The 2 square images attached to AD02003-013 support visual review. When purchasing for distribution, list the target model years and sales markets. That context helps identify catalogue transitions that deserve additional verification. The purchase team can use the recorded result when confirming the order line.
