OVERVIEW
Genuine VW/Audi tail lamp mounting grommet
8K9-805-673-C is the individual grommet for the assigned tail-lamp mounting point. It provides the receiving interface for the matching lamp attachment at the original vehicle location.
This listing supplies one grommet. The tail-lamp assembly, bulb holder, electrical connector, lamp seal and other fasteners are separate components. Identify the damaged mounting point before selecting the repair parts.
Technical details and supplied quantity
- Manufacturer part number: 8K9-805-673-C; compact reference 8K9805673C.
- Brand: Genuine VW/Audi.
- Component: tail-lamp mounting grommet.
- Cataloged replacement for 8K9-805-673-B at the assigned application.
- Quantity: one individual grommet per purchase.
The same vehicle can have different body-mounted and liftgate-mounted lamp components. Match the original mounting profile and lamp position in the vehicle-specific diagram; a general model match does not establish that every lamp attachment uses this grommet.
Common reasons to replace
- The receiving grommet is missing after lamp removal.
- The original grommet is split or distorted.
- A damaged retaining section no longer holds the matching lamp attachment correctly.
- The grommet is damaged during repair of the surrounding lamp mount.
Inspect the lamp-side attachment and body receiving area as well. A broken lamp mount or distorted opening needs its own repair. Water entry or an electrical lighting fault requires diagnosis of the actual seal, housing or circuit; replacing a mounting grommet does not repair those separate faults.

Installation and service guidance
Follow the factory procedure for removing the affected lamp. Support the assembly while its fasteners and electrical connection are released, and record the original grommet position. Remove damaged remnants without distorting the receiving opening.
Inspect the opening and mating lamp attachment, then seat the matching grommet in its prescribed orientation. Align the lamp with the mounting point before applying the specified installation force. Do not use the mounting hardware to pull a misaligned or damaged lamp into place.
Reinstall the separate fasteners and seals according to the applicable repair instructions. Confirm that the lamp sits correctly, its mounting points hold securely and the affected lighting functions operate after reassembly.
