Selection context: Compare both the visible surface and the rear attachment geometry to avoid selecting a cosmetic look-alike.
Post-fit check: Check the opposite side as a reference for height, angle and edge gap before completing the repair.
Quotation details: For a wholesale quotation, provide vehicle details, required side, quantity, destination and a photograph of the removed part.

4K0 945 104 Rear Bumper Light Overview
This product is listed for AUDI A6 2019 at the right rear-bumper position. Some versions are passive reflectors, while others contain a lamp or wiring. The photographed configuration defines the supplied type.
Bumper designs can change during a model cycle, so verify the lens face and hidden support points together.
For this A6 body configuration, check whether the original component uses a separate retainer or an integral locking tab so the approved product can be picked consistently in a mixed wholesale order.
Application and Rear-Bumper Position
Use the product photograph to compare the exposed face and the concealed bracket layout as one assembly.
Production date and regional bumper specification should be reviewed when several near-identical versions are available.
Before approving the A6 part for packing, verify the fastener direction and the shape of the concealed support frame so hidden brackets are not loaded or bent during installation.
Before fitting the right unit, protect the visible surface until the full perimeter gap has been accepted to preserve access for a final electrical test where a lamp circuit is present.
Optical Face and Connector Review
Where a cable is fitted, inspect the seal and connector keying so the replacement does not introduce moisture or terminal stress.
Protect the exposed face from tools and fasteners while the bumper liner is open for access.
While the AUDI bumper opening is accessible, review the reflector texture and lens colour in neutral workshop light to reduce clip damage during a no-force trial installation.
During comparison of the AUDI rear component, record the approved side and vehicle application for repeat-order identification to prevent a visually similar version from sitting proud of the bumper.
Workshop Fitting Sequence
Check the mounting direction and side before installation; left and right components are not automatically interchangeable.
Complete a visual alignment check from the rear and side, then test illumination when wiring is present.
For a repeat order of the right version, confirm that the cable exit, where fitted, clears the bumper reinforcement before the packaging and carton marking are finalized.
On the 2019 A6 bumper layout, confirm that any connector seal remains square when the housing is fully seated before inner liners make the rear attachment points difficult to inspect.

Wholesale Supply and Protective Packing
Trade enquiries should include the vehicle year, model, bumper position and destination market for accurate picking.
Projecting tabs should be supported with shaped material instead of carrying the weight of other products.
At the workshop selection stage for A6, use the opposite-side component only as an alignment reference, not as an interchange part so the visible gap remains even after every retaining point is engaged.
At the right rear-bumper position, compare the outer lens edge with the moulded bumper recess so the lens and housing are supported without distortion.
Frequently Asked Questions
What details help with a wholesale quote?
Provide vehicle, year, side, quantity, destination and clear photographs of the removed component.
Is this component illuminated or reflector-only?
Use the product photographs to confirm whether the rear body carries a connector, bulb holder or LED wiring.
What should be tested after fitting?
Check panel alignment and, for powered versions, verify the intended rear-lighting function before closing access panels.
Can appearance alone confirm compatibility?
No. A similar colour and outline can hide different clips, housing depth, wiring or side orientation.
Why can the same model year use another version?
Regional equipment, facelift changes and bumper trim packages can alter the opening or electrical configuration.
