4K0 945 103 Rear Bumper Light Overview
This product is listed for AUDI A6 2019 at the left rear-bumper position. Rear-bumper lighting improves low-mounted vehicle visibility; reflector-only versions return light without an electrical connection.
A correct vehicle name is only the starting point; market trim and facelift details can change the reflector opening.
During comparison of the AUDI rear component, confirm that the cable exit, where fitted, clears the bumper reinforcement before inner liners make the rear attachment points difficult to inspect.
Vehicle Fitment and Bumper Interface
Review the corner radius, edge return and rear fastening points against the original bumper opening.
Use the removed component as the physical reference for outer shape, housing projection and clip location.
For a repeat order of the left version, confirm that any connector seal remains square when the housing is fully seated so the visible gap remains even after every retaining point is engaged.
On the 2019 A6 bumper layout, use the opposite-side component only as an alignment reference, not as an interchange part so the lens and housing are supported without distortion.
Reflector, Lens and Electrical Configuration
Powered assemblies should be tested for the intended rear-lighting function before the bumper liner is reinstalled.
Check the lens for scratches, cracks and distortion, then compare its moulded edge with the original component.
At the workshop selection stage for A6, compare the outer lens edge with the moulded bumper recess so a passive reflector is not confused with an illuminated assembly.
At the left rear-bumper position, inspect the lower valance and nearby exhaust trim for adequate operating clearance to verify that the photographed configuration matches the vehicle in the workshop.
Installation and Functional Check
Clean the bumper opening, inspect reusable clips and verify an even edge gap before final fastening.
Once seated, inspect the perimeter gap and verify that the bumper surface remains relaxed rather than distorted.
When reviewing the 2019 vehicle, check the rear housing projection against the space behind the bumper skin to avoid contact with wiring, body edges or hot exhaust components.
For the AUDI A6 application, compare the bumper corner radius with the product face from more than one viewing angle to keep the optical face level with the surrounding painted surface.

Wholesale Supply and Protective Packing
Send front and rear photographs when the bumper uses several visually similar lens or wiring configurations.
Before sealing the carton, compare the packed side and quantity with the buyer’s order line.
For this A6 body configuration, align each locating tab with the matching slot before applying hand pressure before any modification is made to the bumper or replacement part.
Before approving the A6 part for packing, check whether the original component uses a separate retainer or an integral locking tab before deciding whether original hardware is suitable for reuse.
Frequently Asked Questions
Which physical points matter most?
Compare exposed shape, housing depth, locating tabs, fastener spacing and any electrical connector.
Can the opposite side use the same part?
Do not assume interchangeability; lens angle, contour, clips and bumper recess are normally side-specific.
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.
When should photographs be supplied?
Send front, rear and bumper-opening images when the original marking is unclear or several versions share the vehicle name.
Can appearance alone confirm compatibility?
No. A similar colour and outline can hide different clips, housing depth, wiring or side orientation.
