8W0 945 104 Rear Bumper Light for AUDI A4 2020 Right
Primary OE reference: 8W0 945 104
Product type: Rear Bumper Light
Applicable vehicle: AUDI A4 2020
Installation position: Rear bumper / reflector opening
Side / orientation: Right
Brand: AUDI
Model: A4
Vehicle year: 2020
Shape and clips: Use the product photograph to compare the exposed face and the concealed bracket layout as one assembly.
Rear visibility role: Rear-bumper lighting improves low-mounted vehicle visibility; reflector-only versions return light without an electrical connection.
Powered-version check: Do not add wiring to a reflector-only application; use the photographs to distinguish illuminated and passive versions.
Workshop guidance: After fitting, inspect flushness from several angles and test the lamp where an electrical function is present.
Selection context: Bumper designs can change during a model cycle, so verify the lens face and hidden support points together.
Post-fit check: For reflector types, confirm correct orientation; for powered types, test the circuit before closing access panels.
Quotation details: For repeat orders, quote the vehicle application and side together so the correct bumper variant is selected.
Packing reference: Side-specific labels reduce picking mistakes during consolidation of mixed bumper-light orders.
8W0 945 104 Rear Bumper Light Overview
This product is listed for AUDI A4 2020 at the right rear-bumper position. Function and fit are linked: the correct optical face must also align with the bumper surface and surrounding trim.
Compare both the visible surface and the rear attachment geometry to avoid selecting a cosmetic look-alike.
When reviewing the 2020 vehicle, align each locating tab with the matching slot before applying hand pressure before any modification is made to the bumper or replacement part.
Model, Year and Side Confirmation
Check the bumper recess, outer contour and clip orientation; similar reflectors can use different hidden mounts.
A correct vehicle name is only the starting point; market trim and facelift details can change the reflector opening.
For the AUDI A4 application, check whether the original component uses a separate retainer or an integral locking tab before deciding whether original hardware is suitable for reuse.
For this A4 body configuration, verify the fastener direction and the shape of the concealed support frame because facelift bumpers can retain the same vehicle name with different apertures.
Reflector Housing and Wiring Details
Do not add wiring to a reflector-only application; use the photographs to distinguish illuminated and passive versions.
Check the lens for scratches, cracks and distortion, then compare its moulded edge with the original component.
Before approving the A4 part for packing, protect the visible surface until the full perimeter gap has been accepted so left- and right-hand stock cannot be mixed during consolidation.
Before fitting the right unit, review the reflector texture and lens colour in neutral workshop light so the approved product can be picked consistently in a mixed wholesale order.
Installation Preparation
After fitting, inspect flushness from several angles and test the lamp where an electrical function is present.
After installation, confirm the lens is level with nearby trim and that no retaining tab has backed out.
While the AUDI bumper opening is accessible, record the approved side and vehicle application for repeat-order identification so hidden brackets are not loaded or bent during installation.
During comparison of the AUDI rear component, confirm that the cable exit, where fitted, clears the bumper reinforcement to preserve access for a final electrical test where a lamp circuit is present.

Wholesale Supply and Protective Packing
Mixed orders should list left and right quantities separately and identify reflector-only and illuminated versions.
Projecting tabs should be supported with shaped material instead of carrying the weight of other products.
For a repeat order of the right version, confirm that any connector seal remains square when the housing is fully seated to reduce clip damage during a no-force trial installation.
On the 2020 A4 bumper layout, use the opposite-side component only as an alignment reference, not as an interchange part to prevent a visually similar version from sitting proud of the bumper.
Frequently Asked Questions
How is a passive reflector checked?
Confirm the lens orientation, reflective face and flush fit without adding wiring that was not present originally.
Can the opposite side use the same part?
Do not assume interchangeability; lens angle, contour, clips and bumper recess are normally side-specific.
How should the visible lens be packed?
Keep it isolated from carton pressure, loose hardware and neighbouring products with separate support for tabs.
Why can the same model year use another version?
Regional equipment, facelift changes and bumper trim packages can alter the opening or electrical configuration.
Can appearance alone confirm compatibility?
No. A similar colour and outline can hide different clips, housing depth, wiring or side orientation.
