8W0 945 105A Rear Bumper Light for AUDI A4 2016 Left

8W0 945 105A Rear Bumper Light Overview

This product is listed for AUDI A4 2016 at the left rear-bumper position. Powered variants work with the vehicle harness; non-powered variants depend on the correct reflective lens and mounting angle.

Production date and regional bumper specification should be reviewed when several near-identical versions are available.

For a repeat order of the left version, 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.

Physical Fitment Evidence

Review the corner radius, edge return and rear fastening points against the original bumper opening.

Check whether the bumper carries a plain reflector or an illuminated unit before approving the replacement.

On the 2016 A4 bumper layout, compare the outer lens edge with the moulded bumper recess so the lens and housing are supported without distortion.

At the workshop selection stage for A4, inspect the lower valance and nearby exhaust trim for adequate operating clearance so a passive reflector is not confused with an illuminated assembly.

Surface, Seal and Electrical Interface

For lamp versions, the connector must lock without force and the harness should route clear of the exhaust and sharp edges.

Protect the exposed face from tools and fasteners while the bumper liner is open for access.

At the left rear-bumper position, check the rear housing projection against the space behind the bumper skin to verify that the photographed configuration matches the vehicle in the workshop.

When reviewing the 2016 vehicle, compare the bumper corner radius with the product face from more than one viewing angle to avoid contact with wiring, body edges or hot exhaust components.

Bumper Assembly Check

Clean the bumper opening, inspect reusable clips and verify an even edge gap before final fastening.

Reinstall the liner only after the housing is secure and the cable, if fitted, has adequate clearance.

For the AUDI A4 application, align each locating tab with the matching slot before applying hand pressure to keep the optical face level with the surrounding painted surface.

For this A4 body configuration, check whether the original component uses a separate retainer or an integral locking tab before any modification is made to the bumper or replacement part.

Wholesale Supply and Protective Packing

For a wholesale quotation, provide vehicle details, required side, quantity, destination and a photograph of the removed part.

Powered versions benefit from a clean connector cover, while reflector versions need firm support around the rear frame.

Before approving the A4 part for packing, verify the fastener direction and the shape of the concealed support frame before deciding whether original hardware is suitable for reuse.

Before fitting the left unit, protect the visible surface until the full perimeter gap has been accepted because facelift bumpers can retain the same vehicle name with different apertures.

Frequently Asked Questions

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.

What if the bumper opening differs?

Stop the installation and compare market version, trim level and hidden mounting geometry before modifying any part.

How should the visible lens be packed?

Keep it isolated from carton pressure, loose hardware and neighbouring products with separate support for tabs.

What details help with a wholesale quote?

Provide vehicle, year, side, quantity, destination and clear photographs of the removed component.

Request a Product-Specific Quote

Where the application is uncertain, send bumper-opening and rear-housing photographs for comparison first.

Fitment evidence: Confirm that the body sits flush in the bumper aperture and that every guide tab faces the correct direction.

Optical configuration: This component completes the rear bumper lighting area and must match the correct side, lens type and vehicle trim.

Selection context: A correct vehicle name is only the starting point; market trim and facelift details can change the reflector opening.

Post-fit check: Complete a visual alignment check from the rear and side, then test illumination when wiring is present.

Bulk supply: Confirm the required quantity and packaging method; exposed lens faces and projecting tabs need separate protection.

Packing reference: The visible face should remain separated from tape, staples and loose hardware throughout transport.
