Product and source-stated application
This tutorial concerns replacement illuminated front dashboard air vents. The archived draft calls them “front air intakes”; the product shown is an interior air vent, not an engine intake.
The written source describes application to 2013–2019 GLA156 vehicles, replacement installation, retention of the original vehicle circuit and matching the factory ambient-lighting function. These are source statements, not verified compatibility or circuit-preservation guarantees for every model year, head unit or kit revision. Confirm the actual vehicle equipment and matching kit before using the electrical instructions.
English installation video
The video below is the exact existing recording linked to this article. It already contains English captions and a CKCP watermark. Its original source and current local copy remain unchanged.
Use these checked viewing points to find the relevant work. They are sample locations, not complete chapter boundaries or an approved installation procedure:
- 00:40 — front-right door trim: a trim tool is used around the upper triangular trim/tweeter area.
- 02:20 — dashboard side trim: the demonstrator handles the side panel near the glovebox.
- 05:15 — front-right door wiring: a close-up shows the door control module and a connector. A visible connector and module label do not establish a verified terminal map.
- 06:30 — front air vents: the view shows the center dashboard vents in the removal section. The English caption describes the removal methods as similar; the complete release points and tool engagement still need review.
- 09:16 — vent installation: the demonstrator holds the center vent and shows its rear light-holder area. In this context, the video's “card space” wording refers to a retaining slot, not a card reader.
- 10:55 — controller connection: the demonstrator points to the module socket while holding a connector; the caption calls it a “5P head.” This is a connector description, not five independently verified pin assignments.
- 11:55 — door-panel refitting: the view shows the rear of the panel and the handle-cable/retaining area.
- 13:58 — lighting demonstration: the center display shows ambient-light color selection, with the vents illuminated green. The Chinese vehicle interface is still visible. This sample does not establish every color, brightness setting or retained factory function.
The video sidebar follows front-right door removal, front-right door wiring, vent removal, vent wiring, vent installation, door refitting and functions. The full sequence should be reviewed in that order.
Controller identity and missing technical details
A source-bound saved frame shows a controller label with “W117,” “5.0” and ports “C,” “B” and “A.” The role and applicability of this labeled controller to the GLA156 kit need confirmation. This does not justify changing the article's vehicle/video binding or applying a different vehicle's instructions. Port letters are not a wiring diagram or a pinout.
The archived article supplies no product still images or wiring diagram, and its effect-display and troubleshooting headings have no detailed text. It does not provide approved power/CAN connections, connector orientation and terminal functions, head-unit/coding requirements, fastener information or a fault tree. These must be completed from the matching kit and vehicle procedure.
Review still required
Continuous caption, audio and action review remains open. The old speech-recognition draft contains repeated text and segments beyond the video duration, so it cannot supply missing instructions. Vent release and light-holder alignment, cable routing and weather-seal treatment, controller compatibility, electrical isolation, refitting and final lighting/airflow/vehicle-function checks still require technical review. The existing recording remains available as a source reference while these gaps are resolved.
